FLAGS - The use of -> instead of = signifies that the indicated register or register

The use of -> instead of = signifies that the indicated register or register
pair contains a pointer to the specified item, rather than the item itself.
Register pairs (such as AX:BX) indicate that the item is split across the
registers, with the high-order half in the first register.

One or more letters may follow the interrupt number; they have the following
meanings:  U - undocumented function, u - partially documented function,
P - available only in protected mode, R - available only in real or V86 mode,
C - callout or callback (usually hooked rather than called),
O - obsolete (no longer present in current versions)

00 - INT 00 C - CPU-generated - DIVIDE ERROR

INT 00 C - CPU-generated - DIVIDE ERROR
Desc:	generated if the divisor of a DIV or IDIV instruction is zero or the
	  quotient overflows the result register; DX and AX will be unchanged.
Notes:	on an 8086/8088, the return address points to the following instruction
	on an 80286+, the return address points to the divide instruction
	an 8086/8088 will generate this interrupt if the result of a division
	  is 80h (byte) or 8000h (word)
SeeAlso: INT 04,OPCODE "AAD"

00 - INT 00 - Zenith - ROM DEBUGGER

INT 00 - Zenith - ROM DEBUGGER
Desc:	invokes the ROM Debugger when at the BIOS level; equivalent to
	  pressing Ctrl-Alt-Ins on booting.
Note:	since DOS revectors INT 00, it is necessary to restore this vector to
	  its original ROM BIOS value in order to invoke the debugger once DOS
	  loads
SeeAlso: INT 03"Columbia"

Top

01 - INT 01 C - CPU-generated - SINGLE STEP

INT 01 C - CPU-generated - SINGLE STEP
Desc:	generated after each instruction if TF (trap flag) is set; TF is
	  cleared on invoking the single-step interrupt handler
Notes:	interrupts are prioritized such that external interrupts are invoked
	  after the INT 01 pushes CS:IP/FLAGS and clears TF, but before the
	  first instruction of the handler executes
	used by debuggers for single-instruction execution tracing, such as
	  MS-DOS DEBUG's T command

01 - INT 01 C - CPU-generated (80386+) - DEBUGGING EXCEPTIONS

INT 01 C - CPU-generated (80386+) - DEBUGGING EXCEPTIONS
Desc:	generated by the CPU on various occurrences which may be of interest
	  to a debugger program
Note:	events which may trigger the interrupt:
	  Instruction address breakpoint fault - will return to execute inst
	  Data address breakpoint trap - will return to following instruction
	  General detect fault, debug registers in use
	  Task-switch breakpoint trap
	  undocumented 386/486 opcode F1h - will return to following instruc

02 - INT 02 C - external hardware - NON-MASKABLE INTERRUPT

INT 02 C - external hardware - NON-MASKABLE INTERRUPT
Desc:	generated by the CPU when the input to the NMI pin is asserted
Notes:	return address points to start of interrupted instruction on 80286+
	on the 80286+, further NMIs are disabled until the next IRET
	  instruction, but one additional NMI is remembered by the hardware
	  and will be serviced after the IRET instruction reenables NMIs
	maskable interrupts may interrupt the NMI handler if interrupts are
	  enabled
	although the Intel documentation states that this interrupt is
	  typically used for power-failure procedures, it has many other uses
	  on IBM-compatible machines:
		Memory parity error: all except Jr, CONV, and some machines
				  without memory parity
		Breakout switch on hardware debuggers
		Coprocessor interrupt: all except Jr and CONV
		Keyboard interrupt: Jr, CONV
		I/O channel check: CONV, PS50+
		Disk-controller power-on request: CONV
		System suspend: CONV
		Real-time clock: CONV
		System watch-dog timer, time-out interrupt: PS50+
		DMA timer time-out interrupt: PS50+
		Low battery: HP 95LX
		Module pulled: HP 95LX

03 - INT 03 C - CPU-generated - BREAKPOINT

INT 03 C - CPU-generated - BREAKPOINT
Desc:	generated by the one-byte breakpoint instruction (opcode CCh)
Notes:	used by debuggers to implement breakpoints, such as MS-DOS DEBUG's G
	  command
	also used by Turbo Pascal versions 1,2,3 when {$U+} specified
	return address points to byte following the breakpoint instruction
	called by Novell DOS 7 EMM386 after displaying an exception error
	  message (GPF, illegal opcodes, etc.) and before waiting for user
	  input
	called by QEMM-386 if the user presses 'I' (undocumented) when prompted
	  after an exception error message

03 - INT 03 - Columbia PCs (desktop,VP portables) - ROM DEBUGGER

INT 03 - Columbia PCs (desktop,VP portables) - ROM DEBUGGER
Desc:	invokes the ROM Debugger if INT 03 has not been revectored; equivalent
	  to pressing Esc on booting.
SeeAlso: INT 00"Zenith",INT 03"Realia"

Top

03 - INT 03 - Realia COBOL - DEBUGGER SUPPORT

INT 03 - Realia COBOL - DEBUGGER SUPPORT
Note:	Realia COBOL checks for a signature eight bytes prior to the interrupt
	  handler when it starts up
BUG:	if the offset of the INT 03 vector is less than 8, the compiler and
	  all executables generated by it will crash the system

03 - INT 03 U - Watcom WVIDEO, Watcom WD - OUTPUT DEBUGGING MESSAGE

INT 03 U - Watcom WVIDEO, Watcom WD - OUTPUT DEBUGGING MESSAGE
	STACK:	DWORD	selector
		DWORD	offset of ASCIZ message to display
Notes:	the INT 03h instruction which invokes the debugger must be followed by
	  a JMP SHORT and the signature string "WVIDEO"
	to check whether this interface is available, define a public byte
	  variable named ___WD_Present, which the debugger will set to 01h
	  before running the program

03 - INT 03 - DTown Utilities - POP UP

INT 03 - DTown Utilities - POP UP
Program: DTown Software Development's DTown Utilities contains various tools
	  which are useful to programmers, such as a memory viewer and
	  disassembler
Note:	DTU pops up on INT 03 (if not hooked by a debugger) to allow the
	  user to inspect memory or code when the machine crashes; various
	  memory managers will invoke INT 03 when displaying a CPU exception
	  error message (either automatically or when the user presses a
	  particular key)

	byte at 0050h:0000h contains status used by default handler
	  00h not active
	  01h PrtSc in progress
	  FFh last PrtSc encountered error
	default handler is at F000h:FF54h in IBM PC and 100%-compatible BIOSes
	since the BOUND instruction also calls INT 05h, but returns control
	  to the BOUND instruction, a failed BOUND check will cause an infinite

06 - INT 06 C - CPU-generated (80186+) - INVALID OPCODE

INT 06 C - CPU-generated (80186+) - INVALID OPCODE
Desc:	this interrupt is generated when the CPU attempts to execute an
	  invalid opcode (most protected-mode instructions are considered
	  invalid in real mode) or a BOUND, LDS, LES, or LIDT instruction
	  which specifies a register rather than a memory address
Notes:	return address points to beginning of invalid instruction
	with proper programming, this interrupt may be used to emulate
	  instructions which do not exist; many 386 BIOSes emulate the 80286
	  undocumented LOADALL instruction which was removed from the 80386+
	generated by the 80386+ when the LOCK prefix is used with instructions
	  other than BTS, BTR, BTC, XCHG, XADD (486), CMPXCHG (486), INC, DEC,

08 - INT 08 C - IRQ0 - SYSTEM TIMER

INT 08 C - IRQ0 - SYSTEM TIMER
Desc:	generated 18.2 times per second by channel 0 of the 8254 system timer,
	  this interrupt is used to keep the time-of-day clock updated
Notes:	programs which need to be invoked regularly should use INT 1C unless
	  they need to reprogram the timer while still keeping the time-of-day
	  clock running at the proper rate
	default handler is at F000h:FEA5h in IBM PC and 100%-compatible BIOSes

08 - INT 08 C - CPU-generated (80286+) - DOUBLE EXCEPTION DETECTED

INT 08 C - CPU-generated (80286+) - DOUBLE EXCEPTION DETECTED
Desc:	called when multiple exceptions occur on one instruction, or an
	  exception occurs in an exception handler
Notes:	called in protected mode if an interrupt above the defined limit of
	  the interrupt vector table occurs
	return address points at beginning of instruction with errors or the
	  beginning of the instruction which was about to execute when the
	  external interrupt caused the exception
	if an exception occurs in the double fault handler, the CPU goes into
	  SHUTDOWN mode (which circuitry in the PC/AT converts to a reset);
	  this "triple fault" is a faster way of returning to real mode on
	  many 80286 machines than the standard keyboard controller reset

09 - INT 09 C - IRQ1 - KEYBOARD DATA READY

INT 09 C - IRQ1 - KEYBOARD DATA READY
Desc:	this interrupt is generated when data is received from the keyboard.
	  This is normally a scan code (from either a keypress *or* a key
	  release), but may also be an ACK or NAK of a command on AT-class
	  keyboards.
Notes:	this IRQ may be masked by setting bit 1 on I/O port 21h
	if the BIOS supports an enhanced (101/102-key) keyboard, it calls
	  INT 15/AH=4Fh after reading the scan code (see #00006) from the
	  keyboard and before further processing; all further processing uses
	  the scan code returned from INT 15/AH=4Fh
	the default interrupt handler is at F000h:E987h in 100%-compatible
	  BIOSes
	the interrupt handler performs the following actions for certain
	  special keystrokes:
	    Ctrl-Break	 clear keyboard buffer, place word 0000h in buffer,
			 invoke INT 1B, and set flag at 0040h:0071h
	    SysReq	 invoke INT 15/AH=85h (SysReq is often labeled SysRq)
	    Ctrl-Numlock place system in a tight wait loop until next INT 09
	    Ctrl-Alt-Del jump to BIOS startup code (either F000h:FFF0h or the
			   destination of the jump at that address)
	    Shift-PrtSc	 invoke INT 05
	    Ctrl-Alt-Plus (HP Vectra) enable keyclick
	    Ctrl-Alt-Plus (many clones) set clock speed to high
	    Ctrl-Alt-Minus (HP Vectra) reduce keyclick volume
	    Ctrl-Alt-Minus (many clones) set clock speed to low
	    Ctrl-Alt-SysReq (HP Vectra) generate hard reset
	    Ctrl-Alt-S	(many clones) run BIOS setup program
	    Ctrl-Alt-Esc (many clones) run BIOS setup program
	    Ctrl-Alt-Ins (many clones) run BIOS setup program
	    Ctrl-Alt-LeftShift-GrayMinus (some clones) turn off system cache
	    Ctrl-Alt-LeftShift-GrayPlus (some clones) turn on system cache
	DR DOS hooks this interrupt to control the cursor shape (underscore/
	  half block) for overwrite/insert mode
	DR Multiuser DOS hooks this interrupt for cursor shape control and to
	  control whether Ctrl-Alt-Del reboots the current session or the
	  entire system

Notes:	scan codes 56h-E1h are only available on the extended (101/102-key)
	  keyboard and Host Connected (122-key) keyboard; scan codes 5Bh-5Dh
	  are only available on the 122-key keyboard and the Microsoft Natural
	  Keyboard; scan codes 5Eh-76h are only available on the 122-key
	  keyboard
	in the default configuration, break codes are the make scan codes with
	  the high bit set; make codes 60h,61h,70h, etc. are not available
	  because the corresponding break codes conflict with prefix codes
	  (code 2Ah is available because the self-test result code AAh is only
	  sent on keyboard initialization).  An alternate keyboard
	  configuration can be enabled on AT and later systems with enhanced
	  keyboards, in which break codes are the same as make codes, but
	  prefixed with an F0h scan code
	prefix code E0h indicates that the following make/break code is for a
	  "gray" duplicate to a key which existed on the original PC keyboard;
	  prefix code E1h indicates that the following make code has no
	  corresponding break code (currently only the Pause key generates no
	  break code)
	the Microsoft Natural Keyboard sends make codes 5Bh, 5Ch, and 5Dh
	  (all with an E0h prefix) for the Left Windows, Right Windows, and
	  Menu keys on the bottom row
	the European "Cherry G81-3000 SAx/04" keyboard contains contacts for
	  four additional keys, which can be made available by a user
	  modification; the three new keys located directly below the cursor
	  pad's Delete, End, and PgDn keys send make codes 66h-68h (F19-F21);
	  the fourth new key, named <delta>, sends make code 73h
	the SysReq key is often labeled SysRq
	the "Accord" ergonomic keyboard with optional touchpad (no other
	  identification visible on keyboard or in owner's booklet) has an
	  additional key above the Grey- key marked with a left-pointing
	  triangle and labeled "Fn" in the owner's booklet which returns
	  scan codes E0h 68h on make and E0h E8h on break
	the "Preh Commander AT" keyboard with additional F11-F22 keys treats
	  F11-F20 as Shift-F1..Shift-F10 and F21/F22 as Ctrl-F1/Ctrl-F2; the
	  Eagle PC-2 keyboard with F11-F24 keys treated those additional keys
	  in the same way
	[Note1] the "Cherry G80-0777" keyboard has additional F11-F15 keys
	  which generate make codes 55h-59h; some other extended keyboards
	  generate codes 55h and 56h for F11 and F12, which cannot be managed
	  by standard DOS keyboard drivers
	[Note2] the Schneider/Amstrad PC1512 PC keyboards contain extra keys,
	  a mouse, and a digital joystick, which are handled like extra keys.
	  The joystick's motion scancodes are converted into standard arrow
	  keys by the BIOS, and the joystick and mouse button scan codes are
	  converted to FFFFh codes in the BIOS keyboard buffer
	  (see CMOS 15h"AMSTRAD").
	  In addition to the keys listed in the table above, there are
	    Del-> (delete forward)	70h
	    Enter			74h

09 - INT 09 C - CPU-generated (80286,80386) - PROCESSOR EXTENSION PROTECTION ERROR

INT 09 C - CPU-generated (80286,80386) - PROCESSOR EXTENSION PROTECTION ERROR
Desc:	called if the coprocessor attempts to access memory outside a segment
	  boundary; it may occur at an arbitrary time after the coprocessor
	  instruction was issued
Notes:	until the condition is cleared or the coprocessor is reset, the only
	  coprocessor instruction which may be used is FNINIT; WAIT or other
	  coprocessor instructions will cause a deadlock because the
	  coprocessor is still busy waiting for data
	for the 486+, a coprocessor protection error generates an INT 0D

0A - INT 0A C - IRQ2 - LPT2 (PC), VERTICAL RETRACE INTERRUPT (EGA,VGA)

INT 0A C - IRQ2 - LPT2 (PC), VERTICAL RETRACE INTERRUPT (EGA,VGA)
Notes:	the TOPS and PCnet adapters use this interrupt request line by default
	DOS 3.2 revectors IRQ2 to a stack-switching routine; DOS 3.3+ does so
	  unless STACKS=0 has been set in CONFIG.SYS.  MS/PC-DOS 3.3+ use the
	  IBM Interrupt Sharing Protocol (see #02568) when hooking this IRQ
	on ATs and above, the physical data line for IRQ2 is labeled IRQ9 and
	  connects to the slave 8259.  The BIOS redirects the interrupt for
	  IRQ9 back here.
	under DESQview, only the INT 15h vector and BASIC segment address (the
	  word at 0000h:0510h) may be assumed to be valid for the handler's
	  process
	many VGA boards do not implement the vertical retrace interrupt,
	  including the IBM VGA Adapter where the traces are either cut or
	  removed

0A - INT 0A C - IRQ2 - Tandy 1000-series HARD DISK

INT 0A C - IRQ2 - Tandy 1000-series HARD DISK
Notes:	this interrupt may be masked by setting bit 2 on I/O port 21h
	the Tandy 1000, 1000A, and 1000HD use IRQ2 for the hard disk; the
	  1000EX, HX, RLX, RLX-HD, RLX-B, RLX-HD-B use IRQ5 instead; the
	  1000RL, RL-HD, SL, SL/2, TL, TL/2, and TL/3 are jumper-selectable
	  for either IRQ2 or IRQ5 (default IRQ5); the 1000SX and TX are
	  DIP-switch selectable for IRQ2 or IRQ5 (default IRQ2); the RSX and
	  RSX-HD use IRQ14.  Tandy systems which use IRQ2 for the hard disk
	  interrupt use IRQ5 for vertical retrace.

Notes:	called in real mode when
	    an instruction accesses a memory operand extending beyond offset
	      FFFFh (i.e. WORD at FFFFh or DWORD at FFFDh or higher) in segment
	      CS, DS, ES, FG, or GS
	    a PUSH MEM or POP MEM instruction contains an invalid bit encoding
	      in the second byte
	    an instruction exceeds the maximum length allowed (10 bytes for
	      80286, 15 bytes for 80386/80486)
	    an instruction wraps from offset FFFFh to offset 0000h
	called in protected mode on protection violations not covered by INT 06
	  through INT 0C, including
	    segment limit violations
	    write to read-only segments
	    accesses using null DS or ES selectors

Notes:
[1] interlaced only
[2] for ATI EGA Wonder, mode 08h is only valid if SMS.COM is loaded resident.
      SMS maps mode 08h to mode 27h if the byte at location 0040:0063 is 0B4h,
      otherwise to mode 23h, thus selecting the appropriate (monochrome or
      color) 132x25 character mode.
    for ATI VGA Wonder, mode 08h is the same, and only valid if VCONFIG loaded
      resident
[3] early XGA boards support 132-column text but do not have this BIOS mode
[4] DESQview intercepts calls to change into these two modes (21h is page 0,
      22h is page 1) even if there is no Hercules graphics board installed
[5] ATI BIOS v4-1.00 has a text-scrolling bug in this mode
[6] for AT&T VDC overlay modes, BL contains the DEB mode, which may be 06h,
      40h, or 44h
[7] BIOS text support is broken in this undocumented mode; scrolling moves
      only about 1/3 of the screen (and does even that portion incorrectly),
      while screen clears only clear about 3/4.
[8] The Oak OTI-037/067/077 modes are present in the Oak VGA BIOS, which OEMs
      may choose to use only partially or not at all; thus, not all Oak boards
      support all "Oak" modes listed here
[9] this card uses the full 128K A000h-BFFFh range for the video buffer,
      precluding the use of a monochrome adapter in the same system
[10] mode 17h supported by Tseng ET4000 BIOS 8.01X dated 1990/09/14, but not
      v8.01X dated 1992/02/28; mode 21h supported by 1992/02/28 version but not
      1990/09/14 version
[11] HERKULES simulates a 90x45 text mode in Hercules graphics mode; the
      installation check for HERKULES.COM is the signature "Herkules" two
      bytes beyond the INT 10 handler
[12] The Realtek RTVGA BIOS v3.C10 crashes when attempting to switch into
      modes 21h or 27h; this version of the BIOS also sets the BIOS data area
      incorrectly for extended text modes, resulting in scrolling after only
      24 lines (the VMODE.EXE	utility does set the data area correctly)
[13] The Tandy 1000SL/TL BIOS does not actually support this mode
[14] HERCULES.COM is a graphics-mode BIOS extension for Hercules-compatible
      graphics cards by Soft Warehouse, Inc.  Its installation check is to
      test whether the word preceding the INT 10 handler is 4137h.
[15] The Hercules-graphics video modes for HERCBIOS (shareware by Dave
      Tutelman) may be changed by a command-line switch; the 90x43
      character-cell mode's number is always one higher than the 90x29 mode
      (whose default is mode 08h)
[16] Stealth64 Video 2001-series BIOS v1.03 reports 76 lines for mode 7Ch,
      resulting in incorrect scrolling for TTY output (scrolling occurs only
      after the end of the 76th line, which is not displayed)
[17] For 43-line text on EGA or 43/50-line text on VGA, you must load an 8x8
      font using AX=1102h after switching to mode 3; VGA may also require
      using INT 10/AH=12h/BL=30h

Notes:	the list of supported video modes is stored in the reserved portion of

	  thus be necessary to either copy the mode list or use a different
	  buffer for all subsequent VESA calls
	not all of the video modes in the list of mode numbers may be
	  supported, e.g. if they require more memory than currently installed
	  or are not supported by the attached monitor.	 Check any mode you
	  intend to use through AX=4F01h first.
	the 1.1 VESA document specifies 242 reserved bytes at the end, so the
	  buffer should be 262 bytes to ensure that it is not overrun; for
	  v2.0, the buffer should be 512 bytes
	the S3 specific video modes will most likely follow the FFFFh
	  terminator at the end of the standard modes.	A search must then
	  be made to find them, FFFFh will also terminate this second list
	in some cases, only a "stub" VBE may be present, supporting only
	  AX=4F00h; this case may be assumed if the list of supported video
	  modes is empty (consisting of a single word of FFFFh)

Notes:	the special mode 81FFh preserves the contents of the video memory and
	  gives access to all of the memory; VESA recommends that the special
	  mode be a packed-pixel mode.	For VBE 2.0+, it is required that the
	  VBE implement the mode, but not place it in the list of available
	  modes (mode information for this mode can be queried directly,
	  however).
	as of VBE 2.0, VESA will no longer define video mode numbers

Notes:	Some implementations of Remote (Initial) Program Loader (RPL/RIPL)
	  don't set bit 0 to indicate a "virtual" floppy drive, although the
	  RPL requires access to its memory image through a faked drive A:.
	  This may have caused problems with releases of DOS 3.3x and earlier,
	  which assumed A: and B: to be invalid drives then and would discard
	  any attempts to access these drives.	Implementations of RPL should
	  set bit 0 to indicate a "virtual" floppy.
	The IBM PC DOS 3.3x-2000 IBMBIO.COM contains two occurences of code
	  sequences like:
	    INT 11h
	    JMP SHORT skip
	    DB 52h,50h,53h; "RPS"
	    skip: OR AX,1
	    TEST AX,1
	  While at the first glance this seems to be a bug since it just
	  wastes memory and the condition is always true, this could well be
	  a signature for an applyable patch to stop it from forcing AX bit 0
	  to be always on. MS-DOS IO.SYS does not contain these signatures,
	  however.
BUGs:	Some old BIOSes didn't properly report the count of floppy drives
	  installed to the system.  In newer systems INT 13h/AH=15h can be
	  used to retrieve the number of floppy drives installed.
	Award BIOS v4.50G and v4.51PG erroneously set bit 0 even if there are
	  no floppy drives installed; use two calls to INT 13/AH=15h to
	  determine whether any floppies are actually installed

1302 - INT 13 - DISK - READ SECTOR(S) INTO MEMORY

INT 13 - DISK - READ SECTOR(S) INTO MEMORY
	AH = 02h
	AL = number of sectors to read (must be nonzero)
	CH = low eight bits of cylinder number
	CL = sector number 1-63 (bits 0-5)
	     high two bits of cylinder (bits 6-7, hard disk only)
	DH = head number
	DL = drive number (bit 7 set for hard disk)
	ES:BX -> data buffer
Return: CF set on error
	    if AH = 11h (corrected ECC error), AL = burst length
	CF clear if successful
	AH = status (see #00234)
	AL = number of sectors transferred (only valid if CF set for some
	      BIOSes)
Notes:	errors on a floppy may be due to the motor failing to spin up quickly
	  enough; the read should be retried at least three times, resetting
	  the disk with AH=00h between attempts
	most BIOSes support "multitrack" reads, where the value in AL
	  exceeds the number of sectors remaining on the track, in which
	  case any additional sectors are read beginning at sector 1 on
	  the following head in the same cylinder; the MSDOS CONFIG.SYS command
	  MULTITRACK (or the Novell DOS DEBLOCK=) can be used to force DOS to
	  split disk accesses which would wrap across a track boundary into two
	  separate calls
	the IBM AT BIOS and many other BIOSes use only the low four bits of
	  DH (head number) since the WD-1003 controller which is the standard
	  AT controller (and the controller that IDE emulates) only supports
	  16 heads
	AWARD AT BIOS and AMI 386sx BIOS have been extended to handle more
	  than 1024 cylinders by placing bits 10 and 11 of the cylinder number
	  into bits 6 and 7 of DH
	under Windows95, a volume must be locked (see INT 21/AX=440Dh/CX=084Bh)
	  in order to perform direct accesses such as INT 13h reads and writes
	all versions of MS-DOS (including MS-DOS 7 [Windows 95]) have a bug
	  which prevents booting on hard disks with 256 heads (FFh), so many
	  modern BIOSes provide mappings with at most 255 (FEh) heads
	some cache drivers flush their buffers when detecting that DOS is
	  bypassed by directly issuing INT 13h from applications.  A dummy
	  read can be used as one of several methods to force cache
	  flushing for unknown caches (e.g. before rebooting).
BUGS:	When reading from floppies, some AMI BIOSes (around 1990-1991) trash
	  the byte following the data buffer, if it is not arranged to an even
	  memory boundary.  A workaround is to either make the buffer word
	  aligned (which may also help to speed up things), or to add a dummy
	  byte after the buffer.
	MS-DOS may leave interrupts disabled on return from this function.
	Apparently some BIOSes or intercepting resident software have bugs
	  that may destroy DX on return or not properly set the Carry flag.
	  At least some Microsoft software frames calls to this function with
	  PUSH DX, STC, INT 13h, STI, POP DX.
	on the original IBM AT BIOS (1984/01/10) this function does not disable
	  interrupts for harddisks (DL >= 80h).	 On these machines the MS-DOS/
	  PC DOS IO.SYS/IBMBIO.COM installs a special filter to bypass the
	  buggy code in the ROM (see CALL F000h:211Eh)

	CH = track number
	DH = head number
	DL = drive number
	ES:BX -> boot sector of future 2M diskette
Return: CF set on error
	CF clear if successful
	AH = status (see #00234)
Program: 2M is a TSR developed by Ciriaco Garc¡a de Celis to support
	  non standard diskettes with 820-902/1476-1558K (5.25 DD/HD)
	  and 984-1066/1804-1886K/3608-3772K (3.5 DD/HD/ED)
InstallCheck: must search for a "CiriSOFT:2M:1.3" or "CiriSOFT:2MX:3.0" or
	  similar (recomended ":2M:", ":2MX:", or ":2MB:" substrings) in the
	  CiriSOFT TSR interface
Notes:	it is not necessary to call AH=17h or AH=18h first (will be ignored)
	the diskette format must always begin on cylinder 0 head 0
	the boot sector can be obtained from an already-formatted 2M diskette
	  (by calling AH=02h with head number 00h in 2M v1.x and with head
	  number 80h for 2M v2+)
	since 2M v2.0, the BOOT sector is emulated using the first physical
	  sector of FAT2; the second-sixth physical sectors of FAT2 in HD or ED
	  diskettes store the SuperBOOT code. To skip the FAT2 emulation (using
	  FAT1) of 2M, in order to read the SuperBOOT code, head number must be
	  80h-81h instead 0-1 (bit 7 active) in standard read/write functions.
	  This lets diskcopy programs format 2M target diskettes copying
	  SuperBOOT code. If the target diskette is already 2MF formatted
	  (containing boot code) this trick it is not necessary.
	when using STV technology (offset 65 of boot sector equal to 1) it is
	  necessary to write the full track before formatting (except track 0
	  side 0) to complete the format and skip future CRC errors on read; in
	  track 0 side 1 the head used must be 81h instead 1. Diskcopy programs
	  may do a format-write-verify sequential phases to improve performance

		 high two bits of maximum cylinder number (bits 7-6)

	    ES:DI -> drive parameter table (floppies only)
Notes:	may return successful even though specified drive is greater than the
	  number of attached drives of that type (floppy/hard); check DL to
	  ensure validity
	for systems predating the IBM AT, this call is only valid for hard
	  disks, as it is implemented by the hard disk BIOS rather than the
	  ROM BIOS
	the IBM ROM-BIOS returns the total number of hard disks attached
	  to the system regardless of whether DL >= 80h on entry.
	Toshiba laptops with HardRAM return DL=02h when called with DL=80h,
	  but fail on DL=81h.  The BIOS data at 40h:75h correctly reports 01h.
	may indicate only two drives present even if more are attached; to
	  ensure a correct count, one can use AH=15h to scan through possible
	  drives
	Reportedly some Compaq BIOSes with more than one hard disk controller
	  return only the number of drives DL attached to the corresponding
	  controller as specified by the DL value on entry.  However, on
	  Compaq machines with "COMPAQ" signature at F000h:FFEAh,
	  MS-DOS/PC DOS IO.SYS/IBMBIO.COM call INT 15/AX=E400h and 
	  INT 15/AX=E480h to enable Compaq "mode 2" before retrieving the count
	  of hard disks installed in the system (DL) from this function.
	the maximum cylinder number reported in CX is usually two less than
	  the total cylinder count reported in the fixed disk parameter table
	  (see INT 41h,INT 46h) because early hard disks used the last cylinder
	  for testing purposes; however, on some Zenith machines, the maximum
	  cylinder number reportedly is three less than the count in the fixed
	  disk parameter table.
	for BIOSes which reserve the last cylinder for testing purposes, the
	  cylinder count is automatically decremented
	on PS/1s with IBM ROM DOS 4, nonexistent drives return CF clear,
	  BX=CX=0000h, and ES:DI = 0000h:0000h
	machines with lost CMOS memory may return invalid data for floppy
	  drives. In this situation CF is cleared, but AX,BX,CX,DX,DH,DI,
	  and ES contain only 0.  At least under some circumstances, MS-DOS/
	  PC DOS IO.SYS/IBMBIO.COM just assumes a 360 KB floppy if it sees
	  CH to be zero for a floppy.
	the PC-Tools PCFORMAT program requires that AL=00h before it will
	  proceed with the formatting
	if this function fails, an alternative way to retrieve the number
	  of floppy drives installed in the system is to call INT 11h.
	In fact, the MS-DOS/PC-DOS IO.SYS/IBMBIO.COM attempts to get the
	  number of floppy drives installed from INT 13/AH=08h, when INT 11h
	  AX bit 0 indicates there are no floppy drives installed. In addition
	  to testing the CF flag, it only trusts the result when the number of
	  sectors (CL preset to zero) is non-zero after the call.
BUGS:	several different Compaq BIOSes incorrectly report high-numbered
	  drives (such as 90h, B0h, D0h, and F0h) as present, giving them the
	  same geometry as drive 80h; as a workaround, scan through disk
	  numbers, stopping as soon as the number of valid drives encountered
	  equals the value in 0040h:0075h
	a bug in Leading Edge 8088 BIOS 3.10 causes the DI,SI,BP,DS, and ES
	  registers to be destroyed
	some Toshiba BIOSes (at least before 1995, maybe some laptops???
	  with 1.44 MB floppies) have a bug where they do not set the ES:DI
	  vector even for floppy drives. Hence these registers should be
	  preset with zero before the call and checked to be non-zero on
	  return before using them.  Also it seems these BIOSes can return
	  wrong info in BL and CX, as S/DOS 1.0 can be configured to preset
	  these registers as for an 1.44 MB floppy.
	the PS/2 Model 30 fails to reset the bus after INT 13/AH=08h and
	  INT 13/AH=15h. A workaround is to monitor for these functions
	  and perform a transparent INT 13/AH=01h status read afterwards.
	  This will reset the bus. The MS-DOS 6.0 IO.SYS takes care of
	  this by installing a special INT 13h interceptor for this purpose.
	AD-DOS may leave interrupts disabled on return from this function.
	Some Microsoft software explicitly sets STI after return.

	  this by installing a special INT 13h interceptor for this purpose.
	Some releases of SpeedStor have a bug where it reports AX=0003h instead
	  of correctly reporting AH=03h for hard disks. A possible workaround
	  when testing for hard disks is to check for AH=03h and AX=0003h.
	  In this case this function should be invoked with a bogus fixed
	  value in AL, e.g. AL=FFh.

	AH = 16h
	DL = drive number (00h-7Fh)
	SI = 0000h (to avoid crash on AT&T 6300)
Return: CF clear if change line inactive
	    AH = 00h (disk not changed)
	CF set if change line active
	    AH = status
		01h invalid command (SyQuest)
		06h change line active or not supported
		80h drive not ready or not present
Notes:	call AH=15h first to determine whether the drive supports a change
	  line
	this call also clears the media-change status, so that a disk change
	  is only reported once
BUGS:	some versions of Award 386 Modular BIOS and AMI BIOS fail to clear
	  the media-change status
	AT&T 6300 WGS systems crash if SI <> 0 on entry.
	some pre 1986/08/04 Compaq ROM BIOS have a serious bug where this
	  function may re-configure a hard disk depending on what is located
	  at ES:[BX] and data indexed to by it. MS-DOS/PC DOS IO.SYS/IBMBIO.COM
	  install a special filter when they detect Compaq ROM BIOSes with
	  earlier dates.
	some Compaq 286 systems have a bug in all INT 13h functions >= 16h,
	  which causes the byte at DS:0074h to be destroyed when called for
	  hard disks (DL >= 80h). MS-DOS/PC DOS IO.SYS/IBMBIO.COM performs a
	  test on this bug using this sub-function, and if found installs a
	  special filter which points DS into ROM, so that it cannot cause
	  any harm.
	some drives (or controllers???) forget the change line status
	  if another drive is accessed afterwards. The DOS BIOS takes care
	  of this by not relying on the reported change line status when
	  the change line is not active and a different drive is accessed,
	  instead it reports "don't know" to the DOS kernel.

Return: AH = error code (0 = no error, -1 = error)
Notes:	The embedded PC can send messages at any time. The managing PC may
	  force the embedded PC to receive messages only after causing a reset
	  on the remote embedded PC.
    !!!from Matthias Paul:
    Description of the high-level control packets:
	After the reset the embedded PC will send a 4-byte packet "LOAD"
	  to the managing PC to indicate it is now able to receive commands.
	The managing PC can send commands using 6-byte sized packets starting
	  with "COMM" followed by a 2-byte command code:
	    "01" demand setup information
	    "02" demand sending of diagnostic information
	If diagnostic information is requested, the embedded PC will send back
	  a header packet starting with 4-byte "DIAG" followed by 2 bytes
	  indicating the count of diagnostic data packets following. Each
	  diagnostic data packet is sized 134 bytes, starting with the 4-byte
	  "DIAG", a 2-byte number packet, followed by 128 bytes of data.
	If setup information is requested, the embedded PC will send back
	  8 bytes length packets starting with "SETP" and 2 byte of setup
	  information of the LOADER and BIOS. The contents varies.
	If the embedded PC requests the managing PC to send a BIOS it will
	  send a 4 byte packet "BIOS".
	The managing PC will then send back a 6-byte sized BIOS header packet
	  starting with "BIOS" and a 2-byte indicator of the BIOS image size
	  in packets.
	The embedded PC will answer by sending a 6 byte packet starting with
	  "BIOS" followed by the running number of the demanded packet.
	The managing PC will then send the requested part of the BIOS image
	  in a 134 byte sized packet, starting with "BIOS", the 2 byte running
	  number of the packet and 128 bytes of the actual BIOS info.
	The embedded PC acknowledges that it received the BIOS with a 6-byte
	  packet "BIOS", followed by 2-bytes of 0.
	If the embedded PCs requests the managing PC to send the operating
	  system, it will follow the same proceduce as for requesting the
	  BIOS. The only difference is that instead of "BIOS", the string
	  "PTOS" will be used in the communication.
	Debug information packets have a length of 32 bytes starting with
	  the 4-byte "DEBU" signature, and followed by the contents of the
	  PCU registers in the following order: SP, SS, ES, DS, BP, DI, SI,
	  DX, CX, BX, AX, IP, CS, Flags. Debug information is send after
	  reaching the corresponding breakpoint.
     Description of the low-level packet protocol:
	Before sending a packet the sending side sends a byte 52h and for a
	  certain time (ca. 1 second for the embedded PC) waits for
	  confirmation (41h) from the receiving side. If no acknowledge is
	  received this	procedure is repeated 4 more times before an error is
	  returned.
	If acknowledge was received the following information is sent:
	 2 BYTEs  synchronization (50h, 50h)
	   BYTE	  data packet size - 1
	 2 BYTEs  CRC of the data
	 var.	  data
	 2 BYTEs  synchronization (F0h, F0h)
	The receiving side must acknowledge this by sending back two bytes
	  59h, 59h. If the sender does not receive the confirmation, it
	  tries 4 more times before returning an error.

	  from this call; thus, the caller should allow interrupts on return
	interrupt handlers may not retain control if the BIOS allows

	AX = 67C3h
	CX = 1Bh
	CS|DS???:SI -> buffer
Return: ES:DI -> ???
	AX = ???
Program: The SK_HGC.COM TSR is used to support operation of ARABIC.COM/
	  HEBREW.COM with the Hercules Graphic Card series of video adapters.
	  It is provided for compatibility with ADOS 3.30/HDOS 3.30 only.
	  This file must be loaded immediately after ARABIC.COM/HEBREW.COM
	  to insure correct operation with these devices.
Notes:	This call is made by the SK_HGC.COM TSR for HGC and HGC/RAMFont
	  graphics adapters when it has successfully detected an Arabic/Hebrew
	  issue of MS-DOS via INT15h/6700h/BX=FFFFh to ensure it runs on the
	  correct version of Arabic or Hebrew MS-DOS.
	At some unknown offset in the buffer it contains a flag indicating
	  if a HGC or HGC/RAMFont adapter is present or not.
	ARABIC/HEBREW does not operate with Monochrome Display Adapters (MDA)
	  and the Hercules Graphic Card Plus (HGC+). ARABIC/HEBREW does operate
	  with Hercules Graphic Card (HGC) with a burnt-in ROM/EPROM font (many
	  HGC cards, even the highly integrated ones, allow for this kind of
	  user customization), though this is not officially supported.
	In some pre-1987 IBM XT/AT and compatibles, the Hercules Graphic
	  Card Plus operates like a MDA card. This hardware limitation
	  prevents ARABIC/HEBREW from running on this combination of hardware.

		80h invalid command (PC,PCjr)
		86h unsupported function (XT,PS30)
Notes:	TSRs which wish to allocate extended memory to themselves often hook
	  this call, and return a reduced memory size.	They are then free to
	  use the memory between the new and old sizes at will.
	the standard BIOS only returns memory between 1MB and 16MB; use AH=C7h
	  for memory beyond 16MB
	not all BIOSes correctly return the carry flag, making this call
	  unreliable unless one first checks whether it is supported through
	  a mechanism other than calling the function and testing CF
	Due to applications not dealing with more than 24-bit descriptors
	  (286), Windows 3.0 has problems when this function reports more
	  than 15 MB. Some releases of HIMEM.SYS are therefore limited to use
	  only 15 MB, even when this function reports more.

	AH = 90h
	AL = device type (see #00507)
	ES:BX -> request block for type codes 80h through BFh
	CF clear
Return: CF set if wait time satisfied
	CF clear if driver must perform wait
	    AH = 00h
Notes:	type codes are allocated as follows:
	  00-7F non-reentrant devices; OS must arbitrate access
	  80-BF reentrant devices; ES:BX points to a unique control block
	  C0-FF wait-only calls, no complementary INT 15/AH=91h call
	floppy and hard disk BIOS code uses this call to implement a timeout;
	  for device types 00h and 01h, a return of CF set means that the
	  timeout expired before the disk responded.
	this function should be hooked by a multitasker to allow other tasks
	  to execute while the BIOS is waiting for I/O completion; the default
	  handler merely returns with AH=00h and CF clear

Return: CF set if BIOS doesn't support call
	CF clear on success
	    ES:BX -> ROM table (see #00509)
	AH = status
	    00h successful
		The PC XT (since 1986/01/10), PC AT (since 1985/06/10), the
		  PC XT Model 286, the PC Convertible and most PS/2 machines
		  will clear the CF flag and return the table in ES:BX.
	    80h unsupported function
		The PC and PCjr return AH=80h/CF set
	    86h unsupported function
		The PC XT (1982/11/08), PC Portable, PC AT (1984/01/10),
		or PS/2 prior to Model 30 return AH=86h/CF set
Notes:	the 1986/1/10 XT BIOS returns an incorrect value for the feature byte
	the configuration table is at F000h:E6F5h in 100% compatible BIOSes
	Dell machines contain the signature "DELL" or "Dell" at absolute FE076h
	  and a model byte at absolute address FE845h (see #00516)
	Hewlett-Packard machines contain the signature "HP" at F000h:00F8h and
	  a product identifier at F000h:00FAh (see #00519)
	Compaq machines can be identified by the signature string "COMPAQ" at
	  F000h:FFEAh, and is preceded by additional information (see #00517)
	Tandy 1000 machines contain 21h in the byte at F000h:C000h and FFh in
	  the byte at FFFFh:000Eh; Tandy 1000SL/TL machines only provide the
	  first three data bytes (model/submodel/revision) in the returned
	  table
	the ID at F000h:C000h is used by some Microsoft software before
	  trusting the floppy flags bits 1 and 0 at 0040h:00B5h.
	the Wang PC contains the signature "WANG" at FC00h:0000h. This is used
	  by Peter Reilley's portable binary editor and viewer BEAV to detect
	  a Wang PC.
	Toshiba laptops contain the signature "TOSHIBA" at FE010h as part of
	  a laptop information record at F000h:E000h (see #00520)
	some AST machines contain the string "COPYRIGHT AST RESEARCH" one byte
	  past the end of the configuration table
	the Phoenix 386 BIOS contains a second version and date string
	  (presumably the last modification for that OEM version) beginning at
	  F000h:FFD8h, with each byte doubled (so that both ROM chips contain
	  the complete information)

INT 15 - DESQview v2.26+ - "PROCESSMEM" - GET TASK MEMORY STATUS
	AX = DE22h
	DX = segment of task handle
Return: DX = total amount of memory in paragraphs
	BX = amount of system memory in paragraphs
	CX = largest block of system memory available in paragraphs
	AX = memory flags (see #00552)
Notes:	if the task handle is a child task, the returned values will be for the
	  process containing the task, rather than the task itself
	if the process's system memory is swapped out, BX,CX,DX remain
	  unchanged, because the memory usage cannot be determined
SeeAlso: AX=DE04h,AX=DE05h,AX=DE06h

Bitfields for DESQview process memory flags:
Bit(s)	Description	(Table 00552)
 0	system memory resides in shared memory

Notes:	originally introduced with the Phoenix BIOS v4.0, this function is

	a maximum of 20 bytes will be transferred at one time, even if ECX is

	  value of ECX on entry, and always copy 20 bytes
	some BIOSes expect the high word of EAX to be clear on entry, i.e.
	  EAX=0000E820h
	if this function is not supported, an application should fall back
	  to AX=E802h, AX=E801h, and then AH=88h
	the BIOS is permitted to return a nonzero continuation value in EBX
	  and indicate that the end of the list has already been reached by
	  returning with CF set on the next iteration
	this function will return base memory and ISA/PCI memory contiguous
	  with base memory as normal memory ranges; it will indicate
	  chipset-defined address holes which are not in use and motherboard
	  memory-mapped devices, and all occurrences of the system BIOS as
	  reserved; standard PC address ranges will not be reported

INT 18 - DISKLESS BOOT HOOK (START CASSETTE BASIC)
Desc:	called when there is no bootable disk available to the system
Notes:	very few PCs other than those produced by IBM contain BASIC in ROM, so
	  the action is unpredictable on compatibles; this interrupt often
	  reboots the system, and often has no effect at all
	some PC and XT clones had an optional IBM CASSETTE BASIC stored
	  in the ROM, too.
	most BIOSes will display an error message similar to "NO BASIC", and
	  either reboot or return to the caller.
	PS/2 machines usually pop up a graphical box to the effect that
	  the user should enter a floppy and press F1.
	Some clones display the message "No boot device available,
	  strike F1 to retry, F2 for setup utility"
	network cards with their own BIOS can hook this interrupt to allow
	  a diskless boot off the network (even when a hard disk is present
	  if none of the partitions is marked as the boot partition)

19 - INT 19 - SYSTEM - BOOTSTRAP LOADER

INT 19 - SYSTEM - BOOTSTRAP LOADER
Desc:	This interrupt reboots the system without clearing memory or restoring
	  interrupt vectors.  Because interrupt vectors are preserved, this
	  interrupt usually causes a system hang if any TSRs have hooked
	  vectors from 00h through 1Ch, particularly INT 08.
Notes:	Usually, the BIOS will try to read sector 1, head 0, track 0 from drive
	  A: to 0000h:7C00h.  If this fails, and a hard disk is installed, the
	  BIOS will read sector 1, head 0, track 0 of the first hard disk.
	  This sector should contain a master bootstrap loader and a partition
	  table (see #00650).  After loading the master boot sector at
	  0000h:7C00h, the master bootstrap loader is given control
	  (see #00653).	It will scan the partition table for an active
	  partition, and will then load the operating system's bootstrap
	  loader (contained in the first sector of the active partition) and
	  give it control.
	true IBM PCs and most clones issue an INT 18 if neither floppy nor hard
	  disk have a valid boot sector
	to accomplish a warm boot equivalent to Ctrl-Alt-Del, store 1234h in
	  0040h:0072h and jump to FFFFh:0000h.	For a cold boot equivalent to
	  a reset, store 0000h at 0040h:0072h before jumping.
	VDISK.SYS hooks this interrupt to allow applications to find out how
	  much extended memory has been used by VDISKs (see #00649).  DOS 3.3+
	  PRINT hooks INT 19 but does not set up a correct VDISK header block
	  at the beginning of its INT 19 handler segment, thus causing some
	  programs to overwrite extended memory which is already in use.
	the default handler is at F000h:E6F2h for 100% compatible BIOSes
	MS-DOS 3.2+ hangs on booting (even from floppy) if the hard disk
	  contains extended partitions which point at each other in a loop,
	  since it will never find the end of the linked list of extended
	  partitions
	under Windows Real and Enhanced modes, calling INT 19 will hang the
	  system in the same was as under bare DOS; under Windows Standard
	  mode, INT 19 will successfully perform a cold reboot as it appears
	  to have been redirected to a MOV AL,0FEh/OUT 64h,AL sequence
BUG:	when loading the remainder of the DOS system files fails, various
	  versions of IBMBIO.COM/IO.SYS incorrectly restore INT 1E before
	  calling INT 19, assuming that the boot sector had stored the
	  contents of INT 1E at DS:SI instead of on the stack as it actually
	  does

1A00 - INT 1A - TIME - GET SYSTEM TIME

INT 1A - TIME - GET SYSTEM TIME
	AH = 00h
Return: CX:DX = number of clock ticks since midnight
	AL = midnight flag, nonzero if midnight passed since time last read
Notes:	there are approximately 18.2 clock ticks per second, 1800B0h per 24 hrs
	  (except on Tandy 2000, where the clock runs at 20 ticks per second)
	IBM and many clone BIOSes set the flag for AL rather than incrementing
	  it, leading to loss of a day if two consecutive midnights pass
	  without a request for the time (e.g. if the system is on but idle)
	since the midnight flag is cleared, if an application calls this
	  function after midnight before DOS does, DOS will not receive the
	  midnight flag and will fail to advance the date
	Modern releases of MS-DOS/PC DOS (5.0+???) assume that AL is a day
	  rollover counter rather than a flag, as expected by older releases.
	  DOS 5 - 7.10 (Windows 98 SE) provide an undocumented CONFIG.SYS
	  SWITCHES=/T option to force the old behaviour of the day advancing
	  code, that is using a flag instead of a counter.
	DR DOS 3.31 - DR-DOS 7.03 handle AL as a flag.

	    CL = year (BCD)

	CF set on error
Notes:	DR-DOS 7.02 (after 1998-06-06) and 7.03 hook this function and correct
	  the century to 20xx if the reported year is 1900..1980 to auto-fix
	  ROM-BIOSes which are not Year 2000 compliant. On a running system,
	  it would also correct the rollover bug from 1999/12/31 to 2000/01/01.
	  The latter can be turned off using the new CONFIG.SYS YEAR2000=ON|OFF
	  command, as hooking INT 1Ah can sometimes cause compatibility
	  problems with 3rd party software, e.g. NCR/Symbios/LSI Logic-based
	  SDMS PCI SCSI drivers (including all OEM drivers like from Asus,
	  Noma, etc.), some Flash-BIOS software like Asus PFLASH, Quarterdeck's
	  QEMM Stealth and Quick-Boot features.
	Using EXCLUDESTEALTHINT=1A, though, will allow QEMM's Stealth features
	  to coexist with the DR-DOS Year 2000 rollover support.
	Actually, the Y2K-fix is provided since OpenDOS 7.02 BETA 2+
	  (1997-08-13), but although these older releases corrected the
	  ROM-BIOS, they didn't pass all Y2K-test suites and had some obscure
	  and inexplicable PCI problems due to the fact that the original
	  INT 1Ah was called via indirect means.  Newer releases, however, use
	  a dynamically fixed-up direct jump to avoid these problems.
	PC DOS 7 plus Y2K fixes and PC DOS 2000 provide similar, though not
	  identical means, which cannot be switched off.
	MS-DOS and older issues of PC DOS do not provide any such means, and
	  thus requires extra Y2K-TSRs to be loaded when run on buggy BIOSes.
BUG:	some BIOSes, such as the 1998/07/25 system ROM in the Compaq Deskpro
	  EP/SB, leave CF unchanged if successful, so CF should be cleared
	  before calling this function

Notes:	the default parameter table (see #01263) is located at F000h:F0A4h for

1E - INT 1E - SYSTEM DATA - DISKETTE PARAMETERS

INT 1E - SYSTEM DATA - DISKETTE PARAMETERS
Notes:	the default parameter table (see #01264) is located at F000h:EFC7h for
	  100% compatible BIOSes
	if the table is changed, INT 13/AH=00h should be called to ensure that
	  the floppy-disk controller is appropriately reprogrammed
	before rebooting the machine, this pointer should be restored to point
	  to the original position of the floppy parameters in the ROM BIOS.
	  The DOS boot sector takes care of this and in the case of a bootstrap
	  error, resets the vector. It also passes the original pointer to the
	  IO.SYS/IBMDOS.COM file for possible later restoration.
	under PhysTechSoft's PTS ROM-DOS this table is fictitious.
	the DR-DOS multi-OS LOADER (at least 1.04 up to including DR-DOS 7.03)
	  does not alter the INT 1Eh vector when launching IBMBIO.COM files
	  via its boot methods "S" or "D".  Although this allows booting
	  (uncompressed) IBMBIO.COM files bigger than 29 KB, it may
	  occasionally cause the floppy parameters to get trashed due to a 
	  bug in the DR-DOS 7.03 IBMBIO.COM startup code.
BUG:	The 2nd level decompressor of the DR-DOS 7.03 IBMBIO.COM (1998/08/11 to
	  1999/07) start-up code erroneously assumes that the floppy parameters
	  reside at 0000h:7C00h (normally set up there by the boot sector)
	  instead of relying on the INT 1Eh vector to point at their location.
	  Since the "assumed" floppy parameters get moved around and INT 1Eh
	  gets updated to point to their new location, this may cause the
	  contents of the floppy params to get trashed, if they weren't
	  actually copied to 0000h:7C00h by the bootstrap loader (that is the
	  boot sector or the LOADER utility).
SeeAlso: INT 13/AH=0Fh,INT 41"HARD DISK 0",INT 4D/AH=0Ah

Format of diskette parameter table:
Offset	Size	Description	(Table 01264)
 00h	BYTE	first specify byte
		bits 7-4: step rate (Fh=2ms,Eh=4ms,Dh=6ms,etc.)
		bits 3-0: head unload time (0Fh = 240 ms)
 01h	BYTE	second specify byte
		bits 7-1: head load time (01h = 4 ms)
		bit    0: non-DMA mode (always 0)
		Note:	The DOS boot sector sets the head load time to 15ms,
			  however, one should retry the operation on failure
 02h	BYTE	delay until motor turned off (in clock ticks)
 03h	BYTE	bytes per sector (00h = 128, 01h = 256, 02h = 512, 03h = 1024)
 04h	BYTE	sectors per track (maximum if different for different tracks)
 05h	BYTE	length of gap between sectors (2Ah for 5.25", 1Bh for 3.5")
 06h	BYTE	data length (ignored if bytes-per-sector field nonzero)
 07h	BYTE	gap length when formatting (50h for 5.25", 6Ch for 3.5")
 08h	BYTE	format filler byte (default F6h)

Notes:	DOS 1.25+ deletes everything in the current directory (including

	  never used) instead of E5h if called on an extended FCB with
	  filename '???????????' and bits 0-4 of the attribute set (bits 1 and
	  2 for DOS 1.x).  This may have originally been an optimization to
	  minimize directory searching after a mass deletion (DOS 1.25+ stop
	  the directory search upon encountering a never-used entry), but can
	  corrupt the filesystem under DOS 2+ because subdirectories are
	  removed without deleting the files they contain.
	currently-open files should not be deleted
	MS-DOS allows deletion of read-only files with an extended FCB, whereas
	  Novell NetWare, DR DOS 6, and Novell DOS 7/OpenDOS 7.01 do not
	this function generates a trap "D" under OS/2 v4.x (Warp4) when called

INT 21 - DOS 1+ - SET INTERRUPT VECTOR
	AH = 25h
	AL = interrupt number
	DS:DX -> new interrupt handler
Notes:	this function is preferred over direct modification of the interrupt
	  vector table
	some DOS extenders place an API on this function, as it is not
	  directly meaningful in protected mode
	under DR DOS 5.0-6.0, this function does not use any of the
	  DOS-internal stacks and may thus be called at any time; however,
	  under Novell DOS 7.0 - DR-DOS 7.02, this function was not reentrant.
	  Since 1998/05/29, DR-DOS 7.03 no longer uses any internal stacks and
	  tests for this function much earlier, to allow a minimal stack usage
	  of just two words in addition to the IRET frame, allowing it to be
	  called from INT 21h functions, specificially device drivers.  This
	  fixes the MCS SMB client
	Novell NetWare (except the new DOS Requester) monitors the offset of
	  any INT 24 set, and if equal to the value at startup, substitutes
	  its own handler to allow handling of network errors; this introduces
	  the potential bug that any program whose INT 24 handler offset
	  happens to be the same as COMMAND.COM's will not have its INT 24
	  handler installed

2126 - INT 21 - DOS 1+ - CREATE NEW PROGRAM SEGMENT PREFIX

INT 21 - DOS 1+ - CREATE NEW PROGRAM SEGMENT PREFIX
	AH = 26h
	DX = segment at which to create PSP (see #01378)
Return: AL destroyed
Notes:	new PSP is updated with memory size information; INTs 22h, 23h, 24h
	  taken from interrupt vector table; the parent PSP field is set to 0
	(DOS 2+) DOS assumes that the caller's CS is the segment of the PSP to
	  copy
BUG:	DR DOS 6.0 original releases 05/1991 & 08/1991 had a problem where the
	  segment from which the PSP was copied was incorrect so that the PSP
	  was not filled correctly and did not contain the command tail.  The
	  DR DOS 6.0 BDOS patch "PAT312" English (1992/01/07, XDIR /C: A0C6h)
	  and later "full" rebuilds fix this problem (see INT 21/AX=4452h).

 7Ch  4 BYTEs	unused
 80h 128 BYTEs	commandline / default DTA
		command tail is BYTE for length of tail, N BYTEs for the tail,
		  followed by a BYTE containing 0Dh
Notes:	in DOS v3+, the limit on simultaneously open files may be increased by
	  allocating memory for a new open file table, filling it with FFh,
	  copying the first 20 bytes from the default table, and adjusting the
	  pointer and count at 34h and 32h.  However, DOS will only copy the
	  first 20 file handles into a child PSP (including the one created on
	  EXEC).
	in an OS/2 DOS box, values of D0h-FEh in the open file table indicate
	  device drivers
	network redirectors based on the original MS-Net implementation use
	  values of 80h-FEh in the open file table to indicate remote files;
	  Novell NetWare also uses values from FEh down to 80h or one more than
	  FILES= (whichever is greater) to indicate remote files (except on
	  OS/2, where is uses CFh down to 80h)
	MS-DOS 5.00 incorrectly fills the FCB fields when loading a program
	  high; the first FCB is empty and the second contains the first
	  parameter
	some DOS extenders place protected-mode values in various PSP fields
	  such as the "parent" field, which can confuse PSP walkers.  Always
	  check either for the CDh 20h signature or that the suspected PSP is
	  at the beginning of a memory block which owns itself (the preceding
	  paragraph should be a valid MCB with "owner" the same as the
	  suspected PSP).
	Novell NetWare updates the fields at offsets 3Eh and 3Fh without
	  checking that a legal PSP segment is current; see AH=50h for further
	  discussion
	for 4DOS and Windows95, the command tail may be more than 126
	  characters; in that case, the length byte will be set to 7Fh (with
	  an 0Dh in the	 127th position at offset FFh), and the first 126
	  characters will be stored in the PSP, with the entire command line
	  in the environment variable CMDLINE; under at least some versions
	  of 4DOS, the byte at offset FFh is *not* set to 0Dh, so there is no
	  terminating carriage return in the PSP's command tail.
BUG:	When shelling out from the Borland Pascal 7.00 IDE, overly-long
	  command lines will not be delimited by a 0Dh character, and the
	  length byte is set to 80h!  A workaround is to always patch in a
	  0Dh at the last position of the command line buffer before scanning
	  the command line.

Format of environment block:
Offset	Size	Description	(Table 01379)
 00h  N BYTEs	first environment variable, ASCIZ string of form "var=value"
      N BYTEs	second environment variable, ASCIZ string
	...
      N BYTEs	last environment variable, ASCIZ string of form "var=value"
	BYTE	00h
---DOS 3.0+ ---
	WORD	number of strings following environment (normally 1)
      N BYTEs	ASCIZ full pathname of program owning this environment
		other strings may follow

INT 21 - DOS 2+ - GET DOS VERSION
	AH = 30h
---DOS 5+ ---
	AL = what to return in BH
	    00h OEM number (see #01394)
	    01h version flag
Return: AL = major version number (00h if DOS 1.x)
	AH = minor version number
	BL:CX = 24-bit user serial number (most versions do not use this)
---if DOS <5 or AL=00h---
	BH = MS-DOS OEM number (see #01394)
---if DOS 5+ and AL=01h---
	BH = version flag
	    bit 3: DOS is in ROM
	    other: reserved (0)
Notes:	the OS/2 v1.x Compatibility Box returns major version 0Ah (10)
	the OS/2 v2.x Compatibility Box returns major version 14h (20)
	OS/2 Warp 3.0 Virtual DOS Machines report v20.30; Warp 4 VDMs report
	  v20.40.
	the Windows NT DOS box returns version 5.00, subject to SETVER
	DOS 4.01 and 4.02 identify themselves as version 4.00; use
	  INT 21/AH=87h to distinguish between the original European MS-DOS 4.0
	  and the later PC-DOS 4.0x and MS-DOS 4.0x
	IBM DOS 6.1 reports its version as 6.00; use the OEM number to
	  distinguish between MS-DOS 6.00 and IBM DOS 6.1 (there was never an
	  IBM DOS 6.0)
	IBM's PC DOS 7 and Y2K updates report themselves as IBM 7.0 to be
	  distinguished from the MS-DOS 7.0 portion of Windows 95.
	MS-DOS 6.21 reports its version as 6.20; version 6.22 returns the
	  correct value
	Windows95 returns version 7.00 (the underlying MS-DOS), as did the
	  "Chicago" beta (reported in _Microsoft_Systems_Journal_,August 1994);
	  Windows95 OSR2 and OSR2.5 (OPK3) return MS version 7.10
	DR DOS 5.0 and 6.0 report version 3.31; Novell DOS 7 reports IBM v6.00,
	  which some software displays as IBM DOS v6.10 (because of the version
	  mismatch in true IBM DOS, as mentioned above).  The Novell DOS 7
	  SETVER.EXE has an undocumented option /G x.y which sets the "global"
	  DOS version returned by this function for all executables not given
	  a specific version number in SETVER to major version x and minor
	  version y.
	Heiko Goeman's Advanced WinDOS 2.10/2.11/2.21 returns "IBM" DOS 5.00
	  (subject to SETVER) and serial number 0.
	All versions of CCI Multiuser DOS up to "CCI Multiuser DOS 7.22 Gold"
	  as of 1997-02-10 report DOS 3.31.
	DR DOS 3.31, 3.32, 3.33, 3.34, 3.35, 3.40, 3.41, 5.0, 6.0 and
	  DR PalmDOS/NetWare PalmDOS 1.0 report version 3.31;
	  DR DOS "Panther" BETA 1 and "StarTrek" report as 5.0.
	  Novell DOS 7, OpenDOS 7.01, DR-OpenDOS 7.02, DR-DOS 7.02, DR-DOS 7.03
	  all report themselves as IBM 6.00, which some software displays as
	  IBM DOS 6.10 (because of the version mismatch in true IBM DOS,
	  as mentioned above). Use INT 21/AX=4452h to distinguish the DR-DOS
	  family from PC DOS.
	The Novell DOS 7 and OpenDOS 7.01 SETVER.EXE has an undocumented
	  option /G x.y which sets the "global" DOS version returned by this
	  function for all executables not given a specific version number in
	  SETVER to major version x >= 5 and minor version y = 0..254,
	  y = 255 is used to disable the BDOS version check at INT 21/AX=4452h.
	A slightly modified option has been documented for DR-OpenDOS 7.02+:
	  in /X mode it now allows for x >= 1, while y >= 100 requires /X mode,
	  and y >= 128 is used to control advanced version control means now
	  (see below).
	DR-DOS 7.02+ IBMDOS.COM (since 1998-01-10) now recognizes optional
	  paths to filenames stored in the SETVER list. Previously such entries
	  were never found. This allows for a three staged model for SETVERed
	  versions:
	  highest priority = entry with path is matching.
	  middle priority = entry without path is matching.
	  lowest priority = use global version (SETVER /G).
	The DR-DOS 7.02+ SETVER 1.01+ (1998-01-12) has also been enhanced to
	  allow DOS *and* BDOS version faking (see INT 21/AX=4452h): In /X mode,
	  setting a sub-version of y = 128..255 will be reported as 0..127 DOS
	  sub-version, sub-versions of y = 100..127 will instead be used to
	  report this value as BDOS version (64h..7Fh) via INT 21/AX=4452h, and
	  the DOS revision stored in PCM_HEADER in the IBMDOS.COM file will
	  be used to report the DOS sub-version (usually this holds 0, but it
	  can be patched to other values, see INT 21/AX=4452h !!!).
	  Note, that DR-DOS SHARE 2.05+ (1998-01-05) has relaxed version
	  checking, and will install on any DOS revision 0..127, as long as
	  run on a DR-DOS 72h+ kernel (formerly it was bound to a revision
	  byte of 0 only).
	Under Novell DOS 7+, the SETVERing also affects the version number
	  WORD stored at offset +40h in each program's PSP (see #01378).
	  This holds true even for special sub-versions of 100..255
	  (see INT 21/AX=4452h).
	generic MS-DOS 3.30, Compaq MS-DOS 3.31, and others identify themselves
	  as PC-DOS by returning OEM number 00h
	the version returned under DOS 4.0x may be modified by entries in
	  the special program list (see #01662 at AH=52h); the version returned
	  under DOS 5+ may be modified by SETVER--use AX=3306h to get the true
	  version number

	  all return IBM 6.00, which some software displays as IBM DOS 6.10
	  (because of the version mismatch in true IBM DOS mentioned for
	  INT 21/AH=30h); versions through Novell DOS 7 Update 15.2 (01/1996)
	  all return revision code 00h. The DOS revision is stored in bits 7-0
	  of the "patch_version" field in the PCM_HEADER structure in the
	  IBMDOS.COM file (see also INT 21/AX=4452h !!!). The version
	  flags (DH) are stored in bits 15-8 of "patch_version", but is updated
	  at runtime to reflect the actual status. "patch_version" is also
	  reported as DX in INT 21/AX=4452h.
	Unlike MS-DOS, under Novell DOS 7+ IBMDOS.COM will also allow to
	  SETVER the returned "true" DOS version same as with INT 21/AX=3000h
	  and INT 21/AX=3001h.
	DR-DOS 7.02+ IBMDOS.COM (since 1998-01-10) now recognizes optional
	  paths to filenames stored in the SETVER list. Previously such
	  entries were never found. This enables a three staged model of
	  SETVERed versions:
	  highest priority = entry with path is matching.
	  middle priority = entry without path is matching.
	  lowest priority = use global version (SETVER /G).
	The DR-DOS 7.02+ SETVER 1.01+ (1998-01-12) has also been enhanced to
	  allow BDOS and DOS version faking (see INT 21/AX=4452h). In /X mode,
	  a set sub-version of y = 128..255 will be reported as 0..127 DOS
	  sub-version, sub-versions of y = 100..127 will be used to report this
	  value as BDOS version (64h..7Fh) with INT 21/AX=4452h instead while
	  bits 6-0 of the DOS revision stored in PCM_HEADER in the IBMDOS.COM
	  file will be used to report the BH DOS sub-version 0..127 (usually
	  this holds 0, but it can be patched to other values).
	DR-DOS SHARE 2.05 (1998-01-05) has relaxed version checking now, and
	  will install on any DOS revision 0..127 (formerly it was bound to
	  DOS revision 0 only), as long as run on a DR-DOS 72h or 73h BDOS
	  kernel.  Hence, if there will be changes in the SHARE implementation
	  without changing the BDOS version, DR-DOS SHARE 2.05 can still be
	  stopped from installing by changing the DOS revision in PCM_HEADER
	  to something in the range 128..255.
	Under Novell DOS 7+, the version SETVERing also affects the version
	  number WORD stored at offset +40h in each program's PSP (see
	  Table xxxx at INT 21/AH=26h). This holds true even for special
	  sub-versions of 100..255 (see INT 21/AX=4452h).
	S/DOS 1.0 (1995) returns a DOS revision of 9, while its own PTS OEM
	  revision still defaults to 0 (see also INT 21/AH=20h"S/DOS").
BUG:	DR DOS 5.0 and 6.0 return CF set/AX=0001h for INT 21/AH=33h
	  subfunctions other than 00h-02h and 05h, while MS-DOS returns AL=FFh
	  for invalid subfunctions

2134 - INT 21 - DOS 2+ - GET ADDRESS OF INDOS FLAG

INT 21 - DOS 2+ - GET ADDRESS OF INDOS FLAG
	AH = 34h
Return: ES:BX -> one-byte InDOS flag
Notes:	this function executes on the DOS stack, and thus cannot be called
	  while another DOS function is already executing; you should use
	  this function once at the beginning of the program and store the
	  returned pointer rather than calling it when requiring DOS access
	the value of InDOS is incremented whenever an INT 21 function begins
	  and decremented whenever one completes
	during an INT 28 call, it is safe to call some INT 21 functions even
	  though InDOS may be 01h instead of zero
	InDOS alone is not sufficient for determining when it is safe to
	  enter DOS, as the critical error handling decrements InDOS and
	  increments the critical error flag for the duration of the critical
	  error.  Thus, it is possible for InDOS to be zero even if DOS is
	  busy.
	SMARTDRV 4.0 sets the InDOS flag while flushing its buffers to disk,
	  then zeros it on completion
	the critical error flag is the byte immediately following InDOS in
	  DOS 2.x, and the byte BEFORE the InDOS flag in DOS 3.0+ and
	  DR DOS 3.41+ (except COMPAQ DOS 3.0, where the critical error flag
	  is located 1AAh bytes BEFORE the critical section flag)
	for DOS 3.1+, an undocumented call exists to get the address of the
	  critical error flag (see AX=5D06h)
	this function was undocumented prior to the release of DOS 5.0.

Notes:	if CX is zero, no data is written, and the file is truncated or
	  extended to the current position
	data is written beginning at the current file position, and the file
	  position is updated after a successful write
	for FAT32 drives, the file must have been opened with AX=6C00h with

	  otherwise the write will fail with error code 0005h (access denied)
	the usual cause for AX < CX on return is a full disk
BUG:	a write of zero bytes will appear to succeed when it actually failed
	  if the write is extending the file and there is not enough disk
	  space for the expanded file (DOS 5.0-6.0); one should therefore check
	  whether the file was in fact extended by seeking to 0 bytes from
	  the end of the file (INT 21/AX=4202h/CX=0000h/DX=0000h)

Notes:	if less than the entire data is read or written, the next read/write
	  continues where the previous one ended; IOCTL calls AX=4402h and
	  AX=4403h both reset the location at which the next operation starts
	  to zero
	the data pointer is also reset to zero if the previous read or write
	  reached or exceeded the end of the data, when the current function
	  is read and the previous was write, or vice versa
	v2.1+ uses a new configuration method, but allows the installation
	  of IPCUST.SYS for backward compatibility with other software which
	  must read the PC/TCP configuration

Notes:	(DOS 3.1+) wildcards are allowed if invoked via AX=5D00h, in which case
	  the filespec must be canonical (as returned by AH=60h), and only
	  files matching the attribute mask in CL are deleted
	DR DOS 5.0-6.0 returns error code 03h if invoked via AX=5D00h; DR DOS
	  3.41 crashes if called via AX=5D00h with wildcards
	DOS does not erase the file's data; it merely becomes inaccessible
	  because the FAT chain for the file is cleared
	deleting a file which is currently open may lead to filesystem
	  corruption.  Unless SHARE is loaded, DOS does not close the handles
	  referencing the deleted file, thus allowing writes to a nonexistant
	  file.
	under DR DOS and DR Multiuser DOS, this function will fail if the file
	  is currently open

Notes:	for origins 01h and 02h, the pointer may be positioned before the
	  start of the file; no error is returned in that case (except under
	  Windows NT), but subsequent attempts at I/O will produce errors
	if the new position is beyond the current end of file, the file will
	  be extended by the next write (see AH=40h); for FAT32 drives, the
	  file must have been opened with AX=6C00h with the "extended size"
	  flag in order to expand the file beyond 2GB
BUG:	using this method to grow a file from zero bytes to a very large size

Notes:	the variant of the call requesting five bytes is an UNDOCUMENTED
	  extension supported by Adaptec's ASPI2DOS.SYS, ASPI4DOS.SYS, and
	  ASPI7DOS.SYS; if made of a host manager which does not support the
	  variant, only four bytes will be returned.  If the variant is
	  supported, Adaptec's WINASPI.DLL assumes that the host manager is
	  an "advanced" one which operates in either real or protected mode
	  (and thus does not require a DPMI INT 31/AX=0301h call to be invoked
	  from protected mode).	 Support of the five-byte variant also appears
	  to imply that an advanced ASPI host manager uses no temporary
	  storage space except the SRB (see #01454) and the stack, and that it
	  is fully reentrant.
	if called with a standard request for four bytes, even Adaptec's
	  advanced drivers return only the requested four bytes containing the
	  ASPI entry point address
	the function address is called with the address of a SCSI Request
	  Block (see #01454) on the stack and the caller must clean up the
	  stack

	AX = 4402h
	BX = file handle for device "386MAX$$"

	    AX = error code (01h,05h,06h,0Dh) (see #01680 at AH=59h/BX=0000h)
Notes:	if the value given in CX is less than the size of the state record
	  (5Ah for v6.01, 66h for v7.00), only a partial state record will be
	  returned
	the state is 40h bytes for 386MAX (actually ASTEMM) v2.20 ("386MAX$$"
	  did not exist yet, use "QMMXXXX0" and then "EMMXXXX0" instead) and
	  56h bytes for v5.11.
	to invoke 386MAX API functions, push DX onto the stack, load DX with
	  the word at offset 25h in the returned state, load all other
	  registers as needed for the desired function, and execute an
	  OUT DX,AL or OUT DX,AX; DX will be set to the pushed value on return
	  if it is not otherwise modified by the API function.	For safety,
	  in case a function is not supported or 386MAX is not present, SP
	  should be saved and restored around the API call.
	Windows 3.1 Standard mode, LAN Manager, and Windows for Workgroups all
	  use the 386MAX API; LAN Manager and Windows for Workgroups reportedly

	  'NRMTx' (NO rewind on close) where x can go from 0 to 3.  There may
	  also be the following names 'MTx' and 'NMTx' which default to 1024
	  byte blocks.	The names may also have a '$' appended to try and make
	  them unique from file names of 'RMT0' etc.
	once opend these devices must be put into RAW mode

	  values
	in DR DOS 3.41-6.0, DX=AX on return; for Novell DOS 7, DH=AH but DL=00h
	  (reportedly, DH=00h when booting NWDOS7 from installation disks)
	Novell DOS 7 returns error code 0001h if SETVER x.255 is in effect for
	  the calling program, or SETVER /G x.255 is in effect
	although based on DR DOS, CCI Multiuser DOS 7.xx,
	  IMS Multiuser DOS 7.x, and IMS REAL/32 7.50+ do not support this call
	With OpenDOS 7.02 BETA 2 and DR-OpenDOS 7.02+, the install check
	  in most tools has been changed to run with both, AH=10h and AH=14h
	  to support possible future "client side" multiuser releases of
	  DR-DOS which may return 14h instead of 10h. Tools should also strip
	  off the CP/Net bit before checking the kernel version.
	  Often used version checks like >= 1070h are invalid, therefore,
	  hence the AH and AL must be checked seperately.
	In DR DOS 3.31-6.0, and DR PalmDOS, DX=AX on return.
	For Novell DOS 7 - DR DOS 7.03 the DX value returned by this function
	  is the same as the DX value returned by INT 21/AX=3306h, and
	  represents the DOS revision (bits 7-0, currently always DL=00h) and
	  the version flags (bits 15-8, with bit 12 = DOS in HMA, bit 11 = DOS
	  in ROM) of the "patch_version" field in the PCM_HEADER structure in
	  the IBMDOS.COM file. The version flags, however, are updated at
	  runtime to reflect the actual system status, resulting, for example,
	  in DH=10h for DOS in HMA, and DH=0 when booting Novell DOS 7 from
	  installation disks.
	The operating system version ID represents the BDOS (Basic Disk
	  Operating System) kernel version (of the DRBDOS.SYS aka IBMDOS.COM
	  file), and the two nibbles can actually be read as CP/M version
	  and sub-version, that is DR-DOS 7.03 (version code 1073h) is
	  actually CP/M-86 version 7.3.
	Due to lost original patch sources from the backups, Caldera OpenDOS
	  7.01 merely represented Novell DOS 7 Update 10 with minor changes.
	For Caldera DR-OpenDOS 7.02, all the Novell DOS 7 patches up to
	  including Update 15.2 have been re-incorporated into the system
	  from other sources, while the missing patches for IBMBIO.COM were
	  independently re-implemented by Matthias Paul in 07/1997-10/1997.
	Novell DOS 7 (since 1993-11-08), OpenDOS 7.01 and OpenDOS 7.02 BETA
	  IBMDOS.COM return error code 0001h if SETVER x.255 is in effect
	  for the calling program, or SETVER /G x.255 is in effect.
	Since Caldera DR-OpenDOS 7.02 the SHARE 2.05+ (1998-01-05) driver
	  uses INT 21/AX=65A2h as an *additional* BDOS version check: If the
	  "FUCASE char" function is functional on a DR-DOS BDOS kernel 72h+,
	  SHARE assumes it is running on an OpenDOS 7.02 BETA 1 (73h) kernel
	  (or later) even if the BDOS version returned by INT 21/AX=4452h would
	  indicate an earlier issue of the kernel. Some 3rd party drivers
	  (like HPFS_DOS.EXE) were hardwired to detect Novell DOS 7 only,
	  and so the kernel version had to be patched back on such systems
	  to allow such drivers to work properly. The BDOS version and DOS
	  revision are stored in PCM_HEADER of the IBMDOS.COM file, see
	  table XXXX below.
	However, this is no longer necessary with the introduction of the
	  DR-DOS 7.02+ IBMDOS.COM (since 1998-01-10) and SETVER 1.01+
	  (since 1998-01-12) because they allow to fake BDOS versions as well
	  as faking DOS versions. In /X mode, a set sub-version of y = 100..127
	  will be used as BDOS version instead (64h..7Fh), while the DOS
	  revision will be used to report the DOS sub-version instead. For
	  example, given a DOS revision of 0, SETVER 6.114 would be the proper
	  value to fake Novell DOS 7 (114=72h) on a DR-DOS 7.02+ system,
	  reporting a DOS version of "IBM" 6.00. Sub-versions 128..255 will
	  completely disable this BDOS version check, and report a DOS sub-
	  version of 0..127. This is to work around problems with possibly
	  hostile programs, that try to detect DR-DOS to not run on this OS.
	Additional version check for 1072h kernels: At API level, there
	  is no known way to distinguish Novell DOS 7 from OpenDOS 7.01,
	  however, an IBMBIO.COM/IBMDOS.COM file date since 1997 and the
	  existance of an environment variable %OS%=OPENDOS usually indicates
	  an OpenDOS system (but not the other way around; some OpenDOS
	  BETAs still used %OS%=NWDOS!).
	Additional version checks for 1073h kernels: A functional test of
	  INT 21/AX=65A2h (see above for SHARE) can be used to distinguish
	  OpenDOS 7.02 BETA 1 from the later (OpenDOS 7.02 BETA 2+ and)
	  DR-OpenDOS 7.02 and DR-DOS 7.02 releases, which are both the
	  same, except for the name change and minor bug fixes. Testing
	  for the INT 21/AX=6601h/BX=0000h bug can be used to differentiate the
	  original release of DR-DOS 7.02 from later 7.02 updates and
	  DR-DOS 7.03.
	The DR DOS version is stored in the environment variable VER.

	  fix for "\\" in cmdline by Quick Basic 4.5/MS PDS 7.1 on Lantastic 4.0
	- DR DOS 6.0 BDOS patch "PAT303" English (1991-12-03, XDIR /C: 66B0h)
	  This patch makes INT 21/AH=4Eh (Search First) compatible with MS-DOS
	  when the Volume Label attribute is set. Previously under DR DOS the
	  volume label was only searched for if bit 3 was the only bit set in
	  the attribute whereas MS-DOS searches for the volume label if bit 3
	  is set, irrespective of any other bits in the attribute.
	- DR DOS 6.0 BDOS patch "PAT306" English (1991-12-11, XDIR /C: 8DE5h)
	  This patch fixes a problem with OPTASM which would give error 8
	  if there were not enough handles available. This patch forces the
	  system to check for available handles before it opens a file.
	- DR DOS 6.0 BDOS patch "PAT312" English (1992-01-07, XDIR /C: A0C6h)
	  This patch fixes a problem with INT 21/AH=26h (create PSP) the
	  segment from which the PSP was copied was incorrect so the the PSP
	  was not filled correctly and did not contain the command tail.
	- DR DOS 6.0 BDOS patch "PAT314" English (1992-01-10, XDIR /C: C964h)

	  after the device driver RCD.SYS v7.x and DOSOAD.SYS v1.x
	- DR DOS 6.0 BDOS patch "PAT317" English (1992-01-27, XDIR /C: B701h)
	  This patch fixes a problem where attempting to close a changed file
	  on a write protected disk seems to work after the first retry.
	  This was caused because when the retry is attempted the file has been
	  marked as not changed, so the attempt to write to disk is not made.
	- DR DOS 6.0 BDOS patch "PAT321" English (1992-02-19, XDIR /C: 947Bh)
	  This patch fixes a problem where the error codes returned from

	  errors were incorrect.
	- DR DOS 6.0 BDOS patch "PAT323" English (1992-02-20, XDIR /C: E1B0h)
	  This patch fixes a problem where, if the first command entered after

	  inform the device driver that a new file handle has been opened.
	  This patch is current and up to date as of 1992-11-10.
	- DR DOS 6.0 update (07/1992)
	- DR DOS 6.0 BDOS patch "PAT301" English (1992-10-28, XDIR /C: 959Bh)
	  This patch fixes a problem with apps that opens a file, with Share
	  loaded, but then cannot delete the file until the file is closed.
	  This causes "Money Manager" to fail.
	- DR DOS 6.0 update (11/1992)
	Note: There is no known method to distinguish these different kernels

	  DR-OpenDOS 7.02+ (now taking a possible multi-user version into
	  account): Most utilities now test for AH being either 10h or 14h,
	  and a BDOS version >=xxh to allow them to properly run on possible
	  future multi-user releases of DR-DOS. Before doing this test, some
	  of them strip off the CP/Net bit.

2148 - INT 21 - DOS 2+ - ALLOCATE MEMORY

INT 21 - DOS 2+ - ALLOCATE MEMORY
	AH = 48h

Return: CF clear if successful
	    AX = segment of allocated block
	CF set on error
	    AX = error code (07h,08h) (see #01680 at AH=59h/BX=0000h)
	    BX = size of largest available block
Notes:	DOS 2.1-6.0 coalesces free blocks while scanning for a block to
	  allocate
	.COM programs are initially allocated the largest available memory
	  block, and should free some memory with AH=49h before attempting any
	  allocations
	under the FlashTek X-32 DOS extender, EBX contains a protected-mode
	  near pointer to the allocated block on a successful return

	    AX = error code (07h,09h) (see #01680 at AH=59h/BX=0000h)
Notes:	apparently never returns an error 07h, despite official docs; DOS 2.1+
	  code contains only an error 09h exit
	DOS 2.1-6.0 does not coalesce adjacent free blocks when a block is
	  freed, only when a block is allocated or resized

	    BX = maximum paragraphs available for specified memory block
Notes:	under DOS 2.1-6.0, if there is insufficient memory to expand the block

214B - INT 21 - DOS 2+ - "EXEC" - LOAD AND/OR EXECUTE PROGRAM

INT 21 - DOS 2+ - "EXEC" - LOAD AND/OR EXECUTE PROGRAM
	AH = 4Bh

		"Exec & Go" (see also AH=80h)
	DS:DX -> ASCIZ program name (must include extension)
	ES:BX -> parameter block (see #01590,#01591,#01592)
	CX = mode (subfunction 04h only)
		0000h child placed in zombie mode after termination
		0001h child's return code discarded on termination
Return: CF clear if successful
	    BX,DX destroyed
	    if subfunction 01h, process ID set to new program's PSP; get with
		INT 21/AH=62h
	CF set on error
	    AX = error code (01h,02h,05h,08h,0Ah,0Bh) (see #01680 at AH=59h)
Notes:	DOS 2.x destroys all registers, including SS:SP
	under ROM-based DOS, if no disk path characters (colons or slashes)
	  are included in the program name, the name is searched for in the
	  ROM module headers (see #01595) before searching on disk
	for functions 00h and 01h, the calling process must ensure that there
	  is enough unallocated memory available; if necessary, by releasing
	  memory with AH=49h or AH=4Ah
	for function 01h, the AX value to be passed to the child program is put
	  on top of the child's stack
	for function 03h, DOS assumes that the overlay is being loaded into
	  memory allocated by the caller
	function 01h was undocumented prior to the release of DOS 5.0
	some versions (such as DR DOS 6.0) check the parameters and parameter
	  block and return an error if an invalid value (such as an offset of
	  FFFFh) is found
	background programs under European MS-DOS 4.0 must use the new
	  executable format
	this function ignores the filename extension, instead checking the
	  first two bytes of the file to determine whether there is a valid
	  .EXE header (see #01594); if not, the file is assumed to be in .COM
	  format.  If present, the file may be in any of several formats which
	  are extensions of the original .EXE format (see #01593)
	.COM-format executables begin running with the following register
	  values:
		AL = 00h if first FCB has valid drive letter, FFh if not
		AH = 00h if second FCB has valid drive letter, FFh if not
		CS,DS,ES,SS = PSP segment
		SP = offset of last word available in first 64K segment
		(note: AX is always 0000h under DESQview)
	old-format executables begin running with the following register
	  values:
		AL = 00h if first FCB has valid drive letter, FFh if not
		AH = 00h if second FCB has valid drive letter, FFh if not
		DS,ES = PSP segment
		SS:SP as defined in .EXE header
		(note: AX is always 0000h under DESQview)
	new executables begin running with the following register values
		AX = environment segment
		BX = offset of command tail in environment segment
		CX = size of automatic data segment (0000h = 64K)
		ES,BP = 0000h
		DS = automatic data segment
		SS:SP = initial stack
	  the command tail corresponds to an old executable's PSP:0081h and
	  following, except that the 0Dh is turned into a NUL (00h); new
	  format executables have no PSP
	under the FlashTek X-32 DOS extender, only function 00h is supported
	  and the pointers are passed in DS:EDX and ES:EBX
	DR DOS 6 always loads .EXE-format programs with no fixups and
	  .COM-format programs starting with 9Ch 55h (PUSHF/PUSH BP) above the
	  64K mark to avoid the EXEPACK bug, by extending the memory block
	  containing the program's environment; this code is disabled if the
	  name of the parent program as stored in the MCB is 'WIN'.
	DR DOS 3.41 and 5.0 check for a valid filename before testing the
	  subfunction number, so the otherwise invalid subfunction 02h will
	  only return error code 01h if the given filename actually exists;
	  otherwise, errors 02h, 03h, or 05h are returned
BUGS:	DOS 2.00 assumes that DS points at the current program's PSP
	Load Overlay (subfunction 03h) loads up to 512 bytes too many if the
	  file contains additional data after the actual overlay
	Load but Do Not Execute (subfunction 01h) is reported to corrupt the
	  top word of the caller's stack if the loaded module terminates with
	  INT 21/AH=4Ch in some versions of MS-DOS, including v5.00.

	  the maximum allocation, however)
	the maximum allocation is set to FFFFh by default

Notes:	for search attributes other than 08h, all files with at MOST the

	  will be returned.  Under DOS 2.x, searching for attribute 08h
	  (volume label) will also return normal files, while under DOS 3.0+
	  only the volume label (if any) will be returned.
	this call also returns successfully if given the name of a character
	  device without wildcards.  DOS 2.x returns attribute 00h, size 0,
	  and the current date and time.  DOS 3.0+ returns attribute 40h and
	  the current date and time.
	immediately after an INT 2F/AX=B711h (APPEND return found name), the
	  name at DS:DX will be overwritten; if AL=00h on entry, the actual
	  found pathname will be stored, otherwise, the actual found path
	  will be prepended to the original filespec without a path.
	under LANtastic, this call may be used to obtain a list of a server's
	  shared resources by searching for "\\SERVER\*.*"; a list of printer
	  resources may be obtained by searching for "\\SERVER\@*.*"
	under the FlashTek X-32 DOS extender, the filespec pointer is in DS:EDX
BUGS:	under DOS 3.x and 4.x, the second and subsequent calls to this function
	  with a character device name (no wildcards) and search attributes
	  which include the volume-label bit (08h) will fail unless there is
	  an intervening DOS call which implicitly or explicity performs a

	some Microsoft applications such as Quick C 2.51 use segments of 0000h
	  and FFFFh and direct access to the SDA (see #01687 at AX=5D06h) to

	on return, ES points at the DOS data segment (see also INT 2F/AX=1203h)
	Quarterdeck's suggested check for the use of its DOSDATA.SYS or
	  DOS-UP.SYS is to test whether the list-of-lists segment is greater
	  than the segment of the first memory block; a better check for
	  DOS-UP.SYS is INT 21/AX=2B01h/CX=444Dh
	because not all DOS workalikes support all fields in the List of Lists,
	  applications should ensure that pointers are neither 0000h:0000h
	  nor FFFFh:FFFFh before using them
	Windows for Workgroups 3.11 network and Windows95 set the path to
	  the local drive and directory even for network drives; in that
	  case the UNC form \\SERVER\SHARE can be obtained with

Return: AL destroyed
Notes:	creates a "child" PSP rather than making an exact copy of the current

	  reference count for each inherited file is incremented
	(DOS 2.0+) sets current PSP to DX
	(DOS 3.0+) marks "no inherit" file handles as closed in child PSP
	this function is implemented using the same code as AH=26h, so unlike

Notes:	allows move between directories on same logical volume
	this function does not set the archive attribute
	  (see #01420 at AX=4301h), which results in incremental backups not
	  backing up the file under its new name
	open files should not be renamed
	(DOS 2.x only) this function renames file by creating a new directory
	  entry with the new name, then marking the old entry deleted
	(DOS 3.0+) allows renaming of directories
	(DOS 3.1+) wildcards are allowed if invoked via AX=5D00h, in which case
	  error 12h (no more files) is returned on success, and both source and
	  destination specs must be canonical (as returned by AH=60h).
	  Wildcards in the destination are replaced by the corresponding char
	  of each source file being renamed.  Under DOS 3.x, the call will fail
	  if the destination wildcard is *.* or equivalent; under DR DOS 5.0,
	  the call will fail with error code 03h if any wildcards are used.
	  When invoked via AX=5D00h, only those files matching the attribute
	  mask in CL are renamed.
	under the FlashTek X-32 DOS extender, the old-name pointer is in DS:EDX
	  and the new-name pointer is in ES:EDI (DS must equal ES)
BUG:	(DR DOS 3.41) when invoked via AX=5D00h, this function will generate
	  a new directory entry with the new name (including any wildcards)
	  which can only be removed with a sector editor

	AH = 5Ah
	CX = file attribute (see #01420 at AX=4301h)
	DS:DX -> ASCIZ path ending with a '\' + 13 zero bytes to receive the
		generated filename
Return: CF clear if successful
	    AX = file handle opened for read/write in compatibility mode
	    DS:DX pathname extended with generated name for temporary file
	CF set on error
	    AX = error code (03h,04h,05h) (see #01680)
Desc:	creates a file with a unique name which must be explicitly deleted
Notes:	under the FlashTek X-32 DOS extender, the path pointer is in DS:EDX
	MS-DOS 3.0-4.0 and DR DOS 3.4-5.0 generate the filename as a sequence
	  of hex digits based on the current date and time; MS-DOS 6+,
	  DR DOS 6, and Novell DOS 7 use letters A-P in place of hex digits
	MS-DOS 5.0 and DR DOS 3.41/5.0 will insert a missing trailing backslash
	  before appending the generated filename, but due to this, an empty
	  string results in a file in the root directory
BUGS:	COMPAQ DOS 3.31 hangs if the pathname is at XXXXh:0000h; it apparently
	  wraps around to the end of the segment
	MS-DOS 5.00 revisions A and B and PC-DOS 5.00 revision A reportedly
	  hang the system if the specified path is the root directory and the
	  root directory is full (no free directory entries)
	Mark Incley <mincley@krisalis.demon.co.uk> reports that this function
	  hangs in MS-DOS 6.2x if the name includes two consecutive path
	  separators (e.g. C:\\ )

	CF set on error
	    AX = error code (03h,04h,05h,50h) (see #01680)
Notes:	unlike AH=3Ch, this function will fail if the specified file exists
	  rather than truncating it; this permits its use in creating semaphore
	  files because it is an atomic "test and set" operation
	under the FlashTek X-32 DOS extender, the filename pointer is in DS:EDX

Return: CF clear if successful

	    AX = error code (01h,06h,21h,24h) (see #01680)
Notes:	error returned unless SHARE or network installed
	an unlock call must specify the same region as some prior lock call
	locked regions become entirely inaccessible to other processes
	duplicate handles created with AH=45h or AH=46h inherit locks, but
	  handles inherited by child processes (see AH=4Bh) do not
	under DR DOS 3.41 and 5.0, if a process opens a file without the no-
	  inherit flag and then starts a child, any locks set by the parent
	  are ignored, and the child will only get an error if it tries to
	  lock an area previously locked by the parent process.	 Under Novell
	  DOS 7, this function is fully supported as in MS-DOS.

Return: as appropriate for function being called
Notes:	does not check AH.  Out of range values will crash the system
	executes using specified computer ID and process ID
	sharing delay loops skipped
	a special sharing mode is enabled to handle FCBs opened across network
	wildcards are enabled for DELETE (AH=41h) and RENAME (AH=56h) under
	  MS-DOS; under DR DOS 3.41, wildcards corrupt the filesystem; and
	  under DR DOS 5.0-6.0, the call returns error code 03h due to improper
	  support for the server function call (refer to BUGS: section below)
	an extra file attribute parameter is enabled for OPEN (AH=3Dh),
	  DELETE (AH=41h), and RENAME (AH=56h)
	functions which take filenames require canonical names (as returned
	  by AH=60h); this is apparently to prevent multi-hop file forwarding
BUGS:	the OS/2 2.0 DOS Boot Session incorrectly maps DOS drive letters,
	  seemingly ignoring HPFS drives
	DR DOS 5.0-6.0 merely recursively call INT 21 after loading the

INT 21 U - DOS 3.0+ internal - GET ADDRESS OF DOS SWAPPABLE DATA AREA
	AX = 5D06h
Return: CF set on error
	   AX = error code (see #01680)
	CF clear if successful
	    DS:SI -> nonreentrant data area (includes all three DOS stacks)
		(critical error flag is first byte) (see #01687)
	    CX = size in bytes of area which must be swapped while in DOS
	    DX = size in bytes of area which must always be swapped
Notes:	the Critical Error flag is used in conjunction with the InDOS flag
	  (see AH=34h) to determine when it is safe to enter DOS from a TSR
	setting CritErr flag allows use of functions 50h/51h from INT 28h under
	  DOS 2.x by forcing use of correct stack
	swapping the data area allows reentering DOS unless DOS is in a
	  critical section delimited by INT 2A/AH=80h and INT 2A/AH=81h,82h
	under DOS 4.0, AX=5D0Bh should be used instead of this function
	SHARE and other DOS utilities consult the byte at offset 04h in the
	  DOS data segment (see INT 2F/AX=1203h) to determine the SDA format
	  in use: 00h = DOS 3.x, 01h = DOS 4.0-6.0, other = error.
	DR DOS 3.41+ supports this function, but the SDA format beyond the
	  first 18h bytes is completely different from MS-DOS
BUG:	calling this function with certain values in DX crashes Novell DOS 7.0
	  prior to Update 14

INT 21 - DOS 3.1+ - SET EXTENDED ERROR INFORMATION
	AX = 5D0Ah
	DS:DX -> 11-word DOS parameter list (see #01686)
Return: nothing.  next call to AH=59h will return values from fields AX,BX,CX,
	  DX,DI, and ES in corresponding registers
Notes:	documented for DOS 5+, but undocumented in earlier versions
	the MS-DOS Programmer's Reference incorrectly states that this call was
	  introduced in DOS 4, and fails to mention that the ERROR structure
	  passed to this function is a DOS parameter list.
BUGS:	DR DOS 3.41 and 5.0 read the value for ES from the DS field of the
	  DPL; fortunately, MS-DOS ignores the DS field, allowing a generic
	  routine which sets both DS and ES fields to the same value
	Novell DOS 7 (through at least Update 4) does not save the pointer,
	  which is always reported as 0000h:0000h by AH=59h; Update 15 fully

Notes:	the input path need not actually exist

	  3.41 and 5.0 do not expand asterisks)
	'.' and '..' in the path are resolved
	filespecs on local drives always start with "d:", those on network
	  drives always start with "\\"
	if path string is on a JOINed drive, the returned name is the one that
	  would be needed if the drive were not JOINed; similarly for a
	  SUBSTed, ASSIGNed, or network drive letter.	Because of this, it is
	  possible to get a qualified name that is not legal under the current
	  combination of SUBSTs, ASSIGNs, JOINs, and network redirections
	under DOS 3.3 through 6.00, a device name is translated differently if
	  the device name does not have an explicit directory or the directory
	  is \DEV (relative directory DEV from the root directory works
	  correctly).  In these cases, the returned string consists of the
	  unchanged device name and extension appended to the string X:/
	  (forward slash instead of backward slash as in all other cases) where
	  X is the default or explicit drive letter.
	under MS-DOS 7.0, this call returns the short name for any
	  long-filename portions of the provided pathname or filename
	functions which take pathnames require canonical paths if invoked via
	  INT 21/AX=5D00h
	supported by OS/2 v1.1 compatibility box
	NetWare 2.1x does not support characters with the high bit set; early
	  versions of NetWare 386 support such characters except in this call.
	  In addition, NetWare returns error code 3 for the path "X:\"; one
	  should use "X:\." instead.
	Novell DOS 7 reportedly has difficulty with non-MS-DOS filenames on
	  network drives, and can return "D:" instead of "SERVER/VOLUME"
	for DOS 3.3-6.0, the input and output buffers may be the same, as the
	  canonicalized name is built in an internal buffer and copied to the
	  specified output buffer as the very last step
	for DR DOS 6.0, this function is not automatically called when on a
	  network.  Device drivers reportedly cannot make this call from their
	  INIT function.  Using the same pointer for both input and output
	  buffers is not supported in the April 1992 and earlier versions of
	  DR DOS
	Windows for Workgroups 3.11, Windows95 and even MS-DOS 7.00 only
	  return the local drive path; to obtain network paths use
	  INT 21/AX=5F02h or INT 21/AX=5F46h instead
	Corel's CORELCDX and MSCDEX without the /S switch return canonical
	  names of the form "\\D.\A.\path", where "D" is the CD-ROM drive
	  letter and "A" appears to indicate the first physical CD-ROM drive;
	  MSCDEX with the /S switch returns a canonical name with embedded
	  blanks.  Novell DOS 7 NWCDEX as of the 11/16/94 update returns the
	  same canonical path as MSCDEX; earlier revisions returned
	  "Cdex.   D:\path", where "D" is the CD-ROM drive letter
	the Windows95 MSCDEX-replacement VxD returns "D:\path", even though the
	  MS-DOS 7.00 MSCDEX behaves identically to older versions (above)
BUG:	Windows95 incorrectly treats filenames where the first two characters
	  after the drive letter and colon are both slashes (either forward
	  or backward) as a UNC (network name) and requires several seconds
	  to attempt to resolve the name before returning an unchanged
	  string

Notes:	not all code pages are available in all versions of DOS or
	  DOS-compatibles, and many (particularly EBCDIC) have not been
	  implemented for *any* DOS to date
	CECP = 'Country Extended CodePage' by IBM.
	Unicode (UCS-2) is a 16-bit character codeset, covering all commonly
	  used characters from almost any language. Not all definitions are
	  fixed at the time of this writing. Unicode will be the future of
	  character coding for the foreseeable future, but is only the
	  "basic multilingual plane" (BMP) subset of 32-bit ISO 10646 codes
	  (UCS-4), a single character set standard covering requirements for
	  all countries and languages, which is still under construction.
	The MS Windows 'ANSI' codepage 1252 (based on the MS Windows 3.0+
	  implementation) appears to be 100% compatible with the code sets
	  used by Amiga OS and Acorn Archimedes RISC-OS and is also a linear
	  subset of the 16bit UniCode code set (UCS-2); the actual ANSI
	  codepage is defined by ISO 8859-1 (Latin 1).
	At least applications for OS/2 Warp 3 Presentation Manager can use
	  EBCDIC codepages, but the codepage ID assignments for EBCDIC
	  codepages are not known for OS/2. OS/2 SAA codepages are not
	  supported in CONFIG.SYS.  Codepage 65400 "Glyphs" is not actually a
	  codepage, but a way to directly access the first 256 of the 383
	  glyphs from the current font set.
	Novell DOS 7/DR DOS 6/Caldera OpenDOS undocumented codepage 853
	  does not necessarily match with MS-DOS' undocumented codepage 853.
	Undocumented codepages 667 and 668 can be found in Russian's PTS/DOS
	  6.51 and S/DOS 1.x DISPLAY.CPI and contain some Eastern European
	  characters.
	Novell NetWare 3.xx clients support UniCode and codepages 437, 850,
	  860, 863, 865, 897, 932, and 1252 (possibly more). NetWare 4.xx
	  clients also support 1250, 1251, 1256. Personal NetWare 1.0 (PNW),
	  as it was distributed in Europe, supports UniCode and codepages 437,
	  850 and 1252.	 Novell's Client32 for DOS/Windows supports 874, 932,
	  936, 949, 950, 1250 - 1257. For codesets not yet available, Novell
	  offers a reduced ASCII 7-bit support through a codepage 0 used as a
	  translation table to UniCode, that supports characters 32-127 except
	  92 ('\').

Desc:	adjust the size of the per-process open file table, thus raising or
	  lowering the limit on the number of files the caller can open
	  simultaneously
Notes:	if BX <= 20, no action is taken if the handle limit has not yet been
	  increased, and the table is copied back into the PSP if the limit
	  is currently > 20 handles
	for file handle tables of > 20 handles, DOS 3.30 never reuses the
	  same memory block, even if the limit is being reduced; this can lead
	  to memory fragmentation as a new block is allocated and the existing
	  one freed
	only the first 20 handles are copied to child processes in DOS 3.3-6.0
	increasing the file handles here will not, in general, increase the
	  number of files that can be opened using the runtime library of a
	  high-level language such as C
	Novell DOS 7 reportedly terminates the calling program if the JFT is
	  being reduced in size and there are any open file handles beyond
	  the portion of the JFT being retained
BUGS:	the original release of DOS 3.30 allocates a full 64K for the handle
	  table on requests for an even number of handles
	DR DOS 3.41 and 5.0 will lose track of any open file handles beyond
	  the portion of the JFT retained after the call; MS-DOS will indicate
	  error 04h if any of the JFT entries to be removed are open

BUG:	this function has bugs (at least in DOS 5.0 and 6.2) when used with
	  drives handled via the network redirector (INT 2F/AX=112Eh):
	    - CX (attribute) is not passed to the redirector if DL=11h,

	Caldera's DPMS-enabled LONGNAME.EXE BETA 1 extension for DR-DOS 7
	  supports the following sub-set of LFN functions: 39h, 3Ah, 3Bh, 41h,
	  43h (BL = 0, 1 only), 47h, 4Eh, 4Fh, 56h, 60h (CL = 0, 1, 2), 6Ch,
	  A0h, A1h, A8h. BETA 2 fixes LFN directory entry checksums, which
	  were causing wrong LFNs to be attached to a file. The 8.3 short
	  names for filenames with exactly 8 chars are no longer abbreviated
	  (e.g. LONGNAME.TXT -> LONGNAME.TXT, not LONGNA~1.TXT). BETA 3 has
	  A7h (BL=0, 1) functions added, and 4Eh/4Fh can return file times
	  in both DOS and 64 bit formats, BETA 4 has support added for
	  Caldera's DRFAT32 redirector extension (see INT 2F/AX=15xxh).
	Caldera's DR-OpenDOS 7.02+ COMMAND.COM utilizes the LFN API as soon
	  as it detects it (mind, that LONGNAME.EXE can be dynamically loaded
	  and unloaded at runtime). This COMMAND.COM shell also works under
	  MS-DOS/PC DOS and in DOS boxes of Windows9x, NT, 2000, and OS/2.
	For 4DOS 6.02+ to work with 3rd party LFN providers, the Win95LFN=Yes
	  directive should be inserted into the 4DOS.INI file.
	Mike Podanoffsky's RxDOS 7.2 provides most of this API natively,
	  including functions 39h, 3Ah, 3Bh, 41h, 43h (BL = ???), 47h, 4Bh,
	  4Eh, 4Fh, 56h, 60h (CL = 0, 1, 2, no CH), 6Ch, A0h, A1h and A7h.
	  However, not all sub-functions seem to be supported yet.

Notes:	on DOS versions which do not support the FAT32 calls, this function
	  returns CF clear/AL=00h (which is the DOS v1+ method for reporting

	under DOS 7.x (i.e. "MSDOS Mode" under Windows95), the ASCIZ string

BUG:	this function returns a maximum of 2GB free space even on an FAT32
	  partition larger than 2GB under some versions of Win95 and Win98,

Desc:	this vector specifies the address of the routine which is to be given

	normally points at the instruction immediately following INT 21/AH=4Bh

	    DOS will abort program with errorlevel 0
	else (RETF/RETF 2 with CF clear or IRET with CF ignored)
	    interrupted DOS call is restarted
Notes:	this interrupt is invoked whenever DOS detects a ^C or ^Break; it
	  should never be called directly
	MS-DOS 1.25 also invokes INT 23 on a divide overflow (INT 00)
	MS-DOS remembers the stack pointer before calling INT 23, and if it is
	  not the same on return, pops and discards the top word; this is what
	  permits a return with RETF as well as IRET or RETF 2
	MS-DOS 2.1+ ignores the returned CF if SP is the same on return as it
	  was when DOS called INT 23, so RETF 2 will not terminate the program
	Novell DOS 7 always pops a word if CF is set on return, so one should
	  not return with RETF 2 and CF set or IRET with the stored flags' CF
	  set
	any DOS call may safely be made within the INT 23 handler, although
	  the handler must check for a recursive invocation if it does
	  call DOS

24 - INT 24 C - DOS 1+ - CRITICAL ERROR HANDLER

INT 24 C - DOS 1+ - CRITICAL ERROR HANDLER
Notes:	invoked when a critical (usually hardware) error is encountered by DOS
	  (see #02543); should never be called directly
	when DOS terminates a program, it copies the previous value of the
	  INT 24 vector out of the PSP (see #01378) and into the interrupt
	  vector table
SeeAlso: INT 21/AH=95h,INT 21/AH=59h/BX=0000h,INT 21/AH=92h"PTS-DOS"

(Table 02543)
Values critical error handler is called with:
	AH = type and processing flags (see #02544)
	AL = drive number if AH bit 7 clear
	BP:SI -> device driver header (see #01646 at INT 21/AH=52h)
		(BP:[SI+4] bit 15 set if character device)
	DI low byte contains error code if AH bit 7 set (see #02545)
	STACK:	DWORD	return address for INT 24 call
		WORD	flags pushed by INT 24
		WORD	original AX on entry to INT 21
		WORD	BX
		WORD	CX
		WORD	DX
		WORD	SI
		WORD	DI
		WORD	BP
		WORD	DS
		WORD	ES
		DWORD	return address for INT 21 call
		WORD	flags pushed by INT 21
Return: AL = action code (see #02546)
	SS,SP,DS,ES,BX,CX,DX preserved
Notes:	the only DOS calls the handler may make are INT 21/AH=01h-0Ch,30h,59h
	if the handler returns to the application by popping the stack, DOS
	  will be in an unstable state until the first call with AH > 0Ch
	for DOS 3.1+, IGNORE (AL=00h) is turned into FAIL (AL=03h) on network
	  critical errors
	if IGNORE specified but not allowed, it is turned into FAIL
	if RETRY specified but not allowed, it is turned into FAIL
	if FAIL specified but not allowed, it is turned into ABORT
	(DOS 3.0+) if a critical error occurs inside the critical error
	  handler, the DOS call is automatically failed (AL set to 03h and
	  the INT 24 call skipped)
	The initial critical error handler is located in the kernel and
	  always results in FAIL. However, by default it is replaced by
	  the critical error handler in the command interpreter when it
	  loads. This can be suppressed (e.g. for BBS systems) by loading
	  the primary DOS 3.00+ COMMAND.COM shell with the undocumented
	  option /F 'Fail'. This syntax is also supported with PTS/DOS 6.51+,
	  S/DOS 1.0+, and DR-OpenDOS 7.02+ (1997-11-13) COMMAND.COM, as well
	  as 4DOS.COM/NDOS.COM.	 OpenDOS 7.01+ COMMAND.COM (1997-03-21)
	  introduced this under /N, which is still supported by newer releases
	  (although it has a slightly different meaning now).
BUG:	DR DOS COMMAND.COM before 1998-05-07 caused incorrect error messages
	  to occur if the error code had a non-zero MSB (e.g. NWCDEX's
	  "IO error reading from device" instead of the correct
	  "not ready error").  This was fixed with the DR-OpenDOS 7.03
	  COMMAND.COM now passing the full error code to any critical error
	  handlers.

Bitfields for critical error type and processing flags:
Bit(s)	Description	(Table 02544)
 7	class
	=0  disk I/O error
	=1  -- if block device, bad FAT image in memory
	    -- if char device, error code in DI
 6	unused
 5	Ignore allowed (DOS 3.0+)
 4	Retry allowed (DOS 3.0+)
 3	Fail allowed (DOS 3.0+)
 2-1	disk area of error
	00 = DOS area	01 = FAT
	10 = root dir	11 = data area
 0	set if write, clear if read
Note:	Abort is always allowed
SeeAlso: #02545,#02546

(Table 02545)
Values for critical error code:
 00h   (0)  write-protection violation attempted
 01h   (1)  unknown unit for driver
 02h   (2)  drive not ready
 03h   (3)  unknown command given to driver
 04h   (4)  data error (bad CRC)
 05h   (5)  bad device driver request structure length
 06h   (6)  seek error
 07h   (7)  unknown media type (non-DOS disk)
 08h   (8)  sector not found
 09h   (9)  printer out of paper
 0Ah  (10)  write fault
 0Bh  (11)  read fault
 0Ch  (12)  general failure
 0Dh  (13)  (DOS 3.0+, "multitasking" DOS, PTS-DOS & S/DOS) sharing violation
 0Eh  (14)  (DOS 3.0+) lock violation
 0Fh  (15)  invalid disk change / wrong disk
 10h  (16)  (DOS 3.0+) FCB unavailable
 10h  (16)  uncertain media
 11h  (17)  (DOS 3.0+) sharing buffer overflow
 11h  (17)  character call interrupted
 12h  (18)  (DOS 4.0+) code page mismatch
 13h  (19)  (DOS 4.0+) out of input
 14h  (20)  (DOS 4.0+) insufficient disk space
Note:	Critical error codes 00h..0Ch are the traditional codes reported
	  through INT 24.  These code assignments are mapped to error codes
	  13h..1Fh reported by INT21/AH=59h (see #01680).  Similarly, the
	  DOS 3.x critical error codes 0Dh..11h are mapped to INT21/AH=59h
	  error codes 20h..24h, however, the DOS 4.0+ critical error codes are
	  not mapped.
BUG:	Paragon Technology Systems' S/DOS 1.0 sources (a stripped down issue
	  of PTS-DOS 6.51 with sources on CD) erroneously list DOS INT 24
	  error	codes 12h..14h as 11h..13h, however, since the sources do not
	  make use of these defines, this seems to be only a documentation
	  error.

25 - INT 25 - DOS 1+ - ABSOLUTE DISK READ (except partitions > 32M)

INT 25 - DOS 1+ - ABSOLUTE DISK READ (except partitions > 32M)
	AL = drive number (00h = A:, 01h = B:, etc)
	CX = number of sectors to read (not FFFFh)
	DX = starting logical sector number (0000h - highest sector on drive)

	    AH = status (see #02547)
	    AL = error code (same as passed to INT 24 in DI)
	    AX = 0207h if more than 64K sectors on drive -- use new-style call
	may destroy all other registers except segment registers
Notes:	original flags are left on stack, and must be popped by caller
	this call bypasses the DOS filesystem
	examination of CPWIN386.CPL indicates that if this call fails with
	  error 0408h on an old-style (<32M) call, one should retry the
	  call with the high bit of the drive number in AL set
	Novell DOS 7 decides whether the old-style or new-style (>32M) version
	  of INT 25 must be used solely on the basis of the partition's size,
	  thus forcing use of the new-style call even for data in the first
	  32M of the partition
	PC Tools MIRROR as shipped with MS-DOS 5.0+ checks several signatures
	  at the beginning of INT 25h and INT 26h before it starts to patch
	  these vectors. The signatures it looks for are 83h, F9h, FFh, 74h
	  (CMP CX,-01; JZ ????) at offset +1 from the INT 25h/26h entry points
	  and 2Eh, FFh, 2Eh (JMP DWORD PTR CS:[????]) at the location pointed
	  to by the JZ ????. If it finds these signatures it will use the
	  target address of the far jump for its sub-sequent checks, otherwise
	  it will just take the previous interrupt entry points when scanning
	  for FAh, 2Eh, 8Ch, 16h (CLI; MOV CS:????,SS) or FAh, 2Eh, 89h, 26h
	  (CLI; MOV CS:????,SP) right at the beginning. Hence, it seems the
	  first two checks are to trace through a specific INT 25h/26h
	  filter. However, the purpose of the whole patch is unknown.
	A method to detect the actual assignments of logical drive numbers
	 to physical BIOS drive units (for example to detect the boot drive),
	 is to temporarily mount an INT 13h handler recording the used DL
	 drive unit for any INT 13/AH=02h read operations and discarding any
	 attempts to access actual floppy drives.  Then call INT 25h for
	 all the appropriate DOS drives and watch the results recorded by
	 the INT 13h interceptor.
	Although all registers except segment registers may be destroyed
	 some software depends on some of the registers being preserved.
	 For example some Flash disk drivers requires that DX is not trashed.
	 DR-DOS 7.03 takes care of this.
BUGS:	DOS 3.1 through 3.3 set the word at ES:[BP+1Eh] to FFFFh if AL is an
	  invalid drive number
	DR DOS 3.41 will return with a jump instead of RETF, leaving the
	  wrong number of bytes on the stack; use the huge-partition version
	  (INT 25/CX=FFFFh) for all partition sizes under DR DOS 3.41
	DR DOS 6.0 original issues 05/1991 & 08/1991 reported wrong error
	  codes for "drive not ready" and "write protect". This was fixed
	  with the DR DOS BDOS patch "PAT321" (1992/02/19, XDIR /C: 947Bh),
	  and later "full" rebuilds (see INT 21/AX=4452h for details).

	 DR-DOS 7.03 takes care of this.
BUGS:	DOS 3.1 through 3.3 set the word at ES:[BP+1Eh] to FFFFh if AL is an
	  invalid drive number
	DR DOS 3.41 will return with a jump instead of RETF, leaving the
	  wrong number of bytes on the stack; use the huge-partition version
	  (INT 26/CX=FFFFh) for all partition sizes under DR DOS 3.41
	DR DOS 6.0 original releases 05/1991 & 08/1991 reported wrong error
	  codes for "drive not ready" and "write protect". This was fixed
	  with the DR DOS BDOS patch "PAT321" (1992/02/19, XDIR /C: 947Bh)
	  and later "full" rebuilds (see INT21/AX=4452h for details).

	    AL = error code (same as passed to INT 24 in DI)
	may destroy all other registers except segment registers
Notes:	partition is potentially >32M (and requires this form of the call) if
	  bit 1 of the device attribute word in the device driver is set
	original flags are left on stack, and must be removed by caller
	this call bypasses the DOS filesystem, though DOS 5+ invalidates any
	  disk buffers referencing sectors which are written with this call
	for FAT32 drives (which may be up to 2TB in size), use INT 21/AX=7305h
	Windows98 will display an error message and deliberately hang the

28 - INT 28 C - DOS 2+ - DOS IDLE INTERRUPT

INT 28 C - DOS 2+ - DOS IDLE INTERRUPT
	SS:SP = top of MS-DOS stack for I/O functions
Return: all registers preserved
Desc:	This interrupt is invoked each time one of the DOS character input
	  functions loops while waiting for input.  Since a DOS call is in
	  progress even though DOS is actually idle during such input waits,
	  hooking this function is necessary to allow a TSR to perform DOS
	  calls while the foreground program is waiting for user input.	 The
	  INT 28h handler may invoke any INT 21h function except functions
	  00h through 0Ch.
Notes:	under DOS 2.x, the critical error flag (the byte immediately after the
	  InDOS flag) must be set in order to call DOS functions 50h/51h from
	  the INT 28h handler without destroying the DOS stacks.
	calls to INT 21/AH=3Fh,40h from within an INT 28 handler may not use a
	  handle which refers to CON
	at the time of the call, the InDOS flag (see INT 21/AH=34h) is normally
	  set to 01h; if larger, DOS is truly busy and should not be reentered
	the default handler is an IRET instruction
	supported in OS/2 compatibility box
	the _MS-DOS_Programmer's_Reference_ for DOS 5.0 incorrectly documents
	  this interrupt as superseded
	the performance of NetWare Lite servers (and probably other peer-to-
	  peer networks) can be dramatically improved by calling INT 28
	  frequently from an application's idle loop

		(00h if call not available)
	    BX = CS of PCXDUMP's INT 28 handler (undocumented)
	    ES = segment of PCXDUMP's memory block (v9.30, undocumented)
Program: PCXDUMP is a shareware screen grabber saving in PCX format
Notes:	if DL<>00h a dump can be requested by calling INT DL as shown
	  below (the user can choose the interrupt number at installation
	  time); if DL=00h the dump function can be called only by hotkeys
	  (this is the default)

(Table 02553)
Call PCXDUMP screen-dump function with:
	INT xx
	AX = 1234h
	BX = dump type
	    0000h Color dump

Notes:	if BX=0001h, 0003h, 0007h or 0008h the whole screen will be
	  dumped; the other valid values will draw a selection frame
	  on the screen except in text modes (text modes allow only
	  full screen dumps)
	this function doesn't perform the dump, it only requests it;
	  the dump will be performed after a few milliseconds if it's

2C - INT 2C R - Cloaking - CALL PROTECTED-MODE PASSALONG CHAIN

INT 2C R - Cloaking - CALL PROTECTED-MODE PASSALONG CHAIN
Notes:	when this interrupt is invoked in V86 mode, RM386 will invoke the first
	  in a chain of protected-mode handlers, and will only pass execution
	  to the V86-mode INT 2C handler if none of the handlers in the
	  passalong chain handle the call instead.  This is the method by which
	  the real-mode stub of a cloaked application communicates with the
	  protected-mode portion.
	the cloaking host calls the passalong chain with EAX=58494E33h ('WIN3')
	  when MS Windows starts up and with EAX=334E4958h ('3NIW') when
	  Windows shuts down; between these two broadcasts, the additional
	  Windows-only Cloaking services are available
	this function was first introduced with RM386 (RAM-MAN/386) v6.00, the
	  memory manager included in Helix Software's Netroom

2D - INT 2D - ALTERNATE MULTIPLEX INTERRUPT SPECIFICATION (AMIS) [v3.6]

INT 2D - ALTERNATE MULTIPLEX INTERRUPT SPECIFICATION (AMIS) [v3.6]
	AH = multiplex number
	AL = function
	    00h installation check
	    01h get private entry point
	    02h uninstall
	    03h request popup
	    04h determine chained interrupts
	    05h get hotkey list
	    06h get device-driver information
	    07h-0Fh reserved for future enhancements
		Return: AL = 00h (not implemented)
	    other  application-dependent
	other registers vary by function (also see individual entries below)
Return: varies by function
Notes:	programs should not use fixed multiplex numbers; rather, a program
	  should scan all multiplex numbers from 00h to FFh, remembering the
	  first unused multiplex in case the program is not yet installed.
	  For multiplex numbers which are in use, the program should compare
	  the first 16 bytes of the signature string to determine whether it
	  is already installed on that multiplex number.  If not previously
	  installed, it should use the first free multiplex number.
	functions other than 00h are not valid unless a program is installed
	  on the selected multiplex number
	to be considered fully compliant with version 3.6 of the specification,
	  programs must implement at least functions 00h, 02h (no resident
	  uninstall code required), and 04h (return value 04h).	 TSRs that
	  provide hotkeys with which the user can activate them must also
	  implement function 05h.  TSRs which provide DOS device drivers must
	  also implement function 06h.	The absolute minimum fully-compliant
	  implementation has an overhead of 64 bytes (80 bytes with function
	  05h) plus 22 bytes per hooked interrupt (for the interrupt sharing
	  protocol header and hook list entry).
	the signature string and description may be used by memory mappers
	  to display the installed programs
	to be considered fully compliant, users of this specification must
	  adhere to the IBM interrupt sharing protocol (see #02568), which will
	  permit removal of TSRs in arbitrary order and interrupt handler
	  reordering.  All TSRs following this specification should be
	  removable unless they are loaded from CONFIG.SYS, though they need
	  not keep the code for removing themselves resident; it is acceptable
	  for a separate program to perform the interrupt unhooking and
	  memory-freeing steps of removal.
	A sample public-domain implementation including example TSRs and
	  utility programs may be found in a separate package distributed as
	  AMISLnnn.ZIP (AMISL092.ZIP as of this writing).
	Please let me know if you choose to follow this proposal.  The
	  signature and a list of the private API calls you use would be
	  appreciated, as well.

Format of interrupt sharing protocol interrupt handler entry point:
Offset	Size	Description	(Table 02568)
 00h  2 BYTEs	short jump to actual start of interrupt handler, immediately
		  following this data block (EBh 10h)
 02h	DWORD	address of next handler in chain
 06h	WORD	signature 424Bh
 08h	BYTE	EOI flag
		00h software interrupt or secondary hardware interrupt handler
		80h primary hardware interrupt handler (will issue EOI to
		      interrupt controller)
 09h  2 BYTEs	short jump to hardware reset routine
		must point at a valid FAR procedure (may be just RETF)
 0Bh  7 BYTEs	reserved (0) by IBM for future expansion
Note:	when chaining to the prior handler, the interrupt handler must perform
	  an indirect jump/call using the address at offset 02h in the
	  ISP header.  This permits another AMIS TSR to hook itself into
	  the chain at a position other than as the first handler to receive
	  an interrupt.

	  needs to scan the return list rather than making additional calls
	  to this function.  If the return is not 00h or 04h, then the caller
	  must cycle through the remaining interrupt numbers it wishes to
	  check.
	return values 01h through 03h may not be used by AMIS v3.6-compliant
	  programs; they are included here solely for compatibility with
	  version 3.3, though they were probably never used in any
	  implementation
	for return values 01h through 03h, since INT 2D is known to be hooked,
	  the resident code need not test for BL=2Dh (to minimize its size),
	  and the return value is therefore undefined in that case.
	this function is not valid unless a program is installed on the
	  specified multiplex number; use INT 2D/AL=00h to check
SeeAlso: INT 2D/AL=00h,INT 2D/AL=01h,INT 2D/AL=02h,INT 2D/AL=03h,INT 2D/AL=05h

	    00h not implemented
	    FFh supported
		DX:BX -> hotkey list (see #02572)
Notes:	this function is not valid unless a program is installed on the

	programs which provide hotkeys are required to provide this function
	  to be fully compliant with this specification

SeeAlso: INT 2D/AL=06h

Format of AMIS hotkey list:
Offset	Size	Description	(Table 02572)
 00h	BYTE	type of hotkey checking (see #02573)
 01h	BYTE	number of hotkeys (may be zero if TSR can disable hotkeys)
 02h 6N BYTEs	array of hotkey definitions
		(one per hotkey, first should be primary hotkey)
		Offset	Size	Description
		 00h	BYTE	hotkey scan code (00h/80h if shift states only)
				hotkey triggers on release if bit 7 set
		 01h	WORD	required shift states (see #02574)
		 03h	WORD	disallowed shift states (see #02574)
		 05h	BYTE	hotkey flags (see #02575)
Notes:	except for bit 7, the shift states correspond exactly to the return
	  values from INT 16/AH=12h.  A set bit in the required states word
	  indicates that the corresponding shift state must be active when the
	  hotkey's scan code is received for the hotkey to be recognized; a
	  clear bit means that the corresponding state may be ignored.	A set
	  bit in the disallowed shift states word indicates that the
	  corresponding shift state must be inactive.
	for the disallowed-states word, if one of the "either" bits is set,
	  then both the corresponding left bit and right bit must be set
	examples:
		Ctrl-Alt-Del monitoring: 53h 000Ch 0003h 06h
		Alt-key tap (DESQview):	 B8h 0000h 0007h 08h

Notes:	this call allows execution of arbitrary commands (including COMMAND.COM
	  internal commands) without loading another copy of COMMAND.COM
	if COMMAND.COM is the user's command interpreter, the primary copy
	  executes the command; this allows the master environment to be
	  modified by issuing a "SET" command, but changes in the master
	  environment will not become effective until all programs descended
	  from the primary COMMAND.COM terminate
	since COMMAND.COM processes the string as if typed from the keyboard,
	  the transient portion needs to be present, and the calling program
	  must ensure that sufficient memory to load the transient portion can
	  be allocated by DOS if necessary
	results are unpredictable if invoked by a program run from a batch file
	  because this call is not reentrant and COMMAND.COM uses the same
	  internal variables when processing a batch file
	hooked but ignored by 4DOS v3.0 COMMAND.COM replacement unless SHELL2E
	  has been loaded
	the MS-DOS 5 Programmer's Reference calls this "Reload Transient"

2F - INT 2F - Multiplex - NOTES

INT 2F - Multiplex - NOTES
	AH = identifier of program which is to handle the interrupt
	   00h-3Fh reserved for IBM (for DOS)
	   40h-7Fh reserved for Microsoft (for DOS)
	   80h-B7h reserved for IBM
	   B8h-BFh reserved for networks
	   C0h-FFh reserved for applications
	AL is the function code
   This is a general mechanism for verifying the presence of a TSR and
   communicating with it.  When searching for a free identifier code for AH
   using the installation check (AL=00h), the calling program should set
   BX/CX/DX to 0000h and must not depend on any registers other than CS:IP
   and SS:SP to be valid on return, since numerous programs now use additional
   registers on input and/or output for the installation check.
Notes:	Since the multiplex chain is growing so long, and beginning to
	  experience multiplex number collisions, I have proposed an alternate
	  multiplex interrupt on INT 2D.  If you decide to use the alternate
	  multiplex, please let me know.
	DOS and some other programs return values in the flags register, so
	  any TSR which chains by calling the previous handler rather than
	  jumping to it should ensure that the returned flags are preserved
	  and passed back to the original caller

2F1000 - INT 2F - SHARE - INSTALLATION CHECK

INT 2F - SHARE - INSTALLATION CHECK
	AX = 1000h
Return: AL = status
	    00h not installed, OK to install
	    01h not installed, not OK to install
	    FFh installed
Notes:	supported by OS/2 v1.3+ compatibility box, which always returns AL=FFh
	if DOS 4.01 SHARE was automatically loaded, file sharing is in an
	  inactive state (due to the undocumented /NC flag used by the autoload
	  code) until this call is made
	DR DOS 5.0 SHARE 1.00 only checks for AH=10h and in this case does not
	  chain to a previous handler, DR DOS 6.0 SHARE 1.02+ properly chains
	  for any values other than AX=1000h and the private FDOS hook
	  AX=1001h.  However, under DR PalmDOS and Novell DOS 7+, the
	  SHARE 2.00+ only tests for the AX=1000h install check, since it no
	  longer uses AX=1001h to hook into the system.
	DOS 5+ chains to the previous handler if AL <> 00h on entry
	Windows Enhanced mode hooks this call and reports that SHARE is
	  installed even when it is not
BUGS:	values of AL other than 00h put DOS 3.x SHARE into an infinite loop
	  (08E9: OR  AL,AL
	   08EB: JNZ 08EB) <- the buggy instruction (DOS 3.3)
	values of AL other than described here put PC-DOS 4.00 into the same
	  loop (the buggy instructions are the same)

2F1001 - INT 2F U - DR DOS 6.0+ FDOS EXTENSIONS - INSTALL FDOS HOOK (SHARE / DELWATCH)

INT 2F U - DR DOS 6.0+ FDOS EXTENSIONS - INSTALL FDOS HOOK (SHARE / DELWATCH)
	AX = 1001h
	DX:BX -> new FDOS stub entry function
Return: nothing
Notes:	the default handler for the pointer set by this call under DELWATCH
	  simply returns with CF set
	In Digital Research terminology FDOS is the part of the BDOS kernel
	  (IBMDOS.COM) responsible for the file system and related tasks, and
	  its functionality is also used by the BDOS kernel itself. However,
	  for reasons of performance and code size, it uses direct calling.
	This interrupt allows external components like SHARE file locking or
	  DELWATCH delete tracking software to hook into the internal backdoor
	  INT 2F/AH=10h/AL<=09h chain in the kernel, so that they can actually
	  allows the kernel to ensure that several conditions are met when
	  passing control to these registered components including proper
	  maintaining A20, re-enterancy, or critical section mutexing
	  (e.g. getting the disk sub-system queue "MXdisk").
	The default handler in the BDOS just sets the carry flag and returns.
	Currently known clients to this shared interface are DR DOS 6.0
	  SHARE 1.xx, DR DOS 6.0+ DELWATCH 1.00+, which both chain onto
	  the same call far address, and the version of AddStor's SuperStor
	  which is bundled with DR DOS 6.0
	However, the DR PalmDOS, and Novell DOS 7 - DR-DOS 7.03 SHARE 2.00-2.05
	  do not use this function to hook into the system. Instead they fix up
	  the share stubs directly. DR PalmDOS SHARE 2.00 uses the stubs at
	  Table !!! INT 21/AH=52h, while Novell DOS 7 - DR-DOS 7.03
	  SHARE 2.01-2.05 use the private set of share stubs at Table !!! at
	  INT 21/AX=4458h).  Future releases may possibly again fix up the
	  share stubs at INT 21/AH=52h.

Notes:	functions marked "OS hook" must under no circumstances by called by

	two functions have been swapped between DELWATCH 1.x and DELWATCH 2.0
	  to ensure that DELWATCH 1.x calls will not do anything under newer
	  versions of the OS; for the same reason, the drive number in AL
	  sometimes requires that bit 7 be set for DELWATCH 2.0+.

2F10FF - INT 2F U - DR DOS 5.0 - FIXUP SHARE STUB TABLE???

INT 2F U - DR DOS 5.0 - FIXUP SHARE STUB TABLE???
	AX = 10FFh
	ES:BX -> new SHARE stub table to use???
Return: DS destroyed???
Notes:	Sets a pointer in the kernel. ES:BX points to a structure in SHARE's
	  segment, which presumeably contains a number (4 or 11???) of entries
	  of 5 bytes each and is probably part of some kind of share stub
	  dispatcher that gets fixed up by this call.
	This was seen called by DR DOS 5.0 SHARE 1.00 (when INT 2F/AX=1000h
	  revealed that SHARE was not installed) before it hooked INT 2Fh
	  via INT 21/AH=35h to provide its install check function. It preserved
	  the DS register before calling.
	However, the DR DOS 6.0+ SHARE 1.02+ uses INT 2F/AX=1001h to hook
	  into the OS, DR PalmDOS SHARE 2.00 directly fixes up the share stubs
	  in table !!! at INT 21h/52h, and Novell DOS 7 - DR-DOS 7.03
	  SHARE 2.01-2.05 maintains the private set of share stubs in
	  Table !!! at INT 21/AX=4458h).
	This function was probably used between 1990/02/09 and 1991/03/15.

Notes:	this is the only call which may be made directly to the NetWare
	  redirector from an application
	COMMAND.COM's COPY and DOS's XCOPY reportedly call INT 21/AX=1127h in
	  order to speed up copies between files on the same network server;
	  if error code 11h (not same device) is returned, the copy is
	  performed in the usual manner.  However, no such calls appear to
	  be present in MS-DOS 6.22.
	From the DR DOS "Panther" BETA COMMAND.COM (1992/06/22) up to some of
	  the Novell DOS 7 COMMAND.COM updates (1994/09/12), the shell made
	  calls to INT 2F/AX=11F0h to attempt "remote server COPYing". However,
	  this was removed from later releases of the shell because it stopped
	  Performance Technologies' PowerLAN 3.1 working. (A successor of
	  the DR-DOS 7.03 COMMAND.COM may possibly reintroduce this remote
	  copy feature.	 Probably it would then try both INT 2F/AX=1127h and
	  INT 2F/AX=11F0h.)

Notes:	From the DR DOS "Panther" BETA COMMAND.COM (1992/06/22) up to some of
	  the Novell DOS 7 COMMAND.COM updates (1994/09/12), the shell made
	  calls to INT 2F/AX=11F0h to attempt "remote server COPYing". However,
	  this was removed from later releases of the shell because it 
	  interfered with Performance Technologies' PowerLAN 3.1. (A successor
	  of the DR-DOS 7.03 COMMAND.COM may possibly reintroduce this remote
	  copy feature. Probably it would then try both INT 2F/AX=1127h and
	  INT 2F/AX=11F0h.)

Notes:	This function is known to be supported by Paragon Technology Systems
	  PTS-DOS 6.51 and S/DOS 1.0, and probably was also supported
	  in earlier releases.  It is handled from within the kernel's
	  INT 2Fh dispatcher.
	Resident system extensions should call INT 2Fh/12F0h to intercept
	  the INT 2Fh chain. The main idea of this call is to allow them to
	  be moved to the HMA and intercept INT 2Fh without querying A20 state
	  and without interception of the INT2Fh vector. This is why the
	  "Chain2F" variable must be instanced by placing it to the SDA.
	On chain entry of the far procedure, CF must be set.  All registers
	  except for AX, BP, and DS remain unchanged. If a handler cannot
	  process the call, it must set CF and do a far jump to the previous
	  one in the chain in order to indicate an error.  If CF is still set
	  on exit, the call will be ignored.

2F13 - INT 2F U - DOS 3.2+ - SET DISK INTERRUPT HANDLER

INT 2F U - DOS 3.2+ - SET DISK INTERRUPT HANDLER
	AH = 13h
	DS:DX -> interrupt handler disk driver calls on read/write
	ES:BX = address to restore INT 13 to on system halt (exit from root
		 shell) or warm boot (INT 19)
Return: DS:DX set by previous invocation of this function
	ES:BX set by previous invocation of this function
Notes:	IO.SYS hooks INT 13 and inserts one or more filters ahead of the
	  original INT 13 handler.  The first is for disk change detection
	  on floppy drives, the second is for tracking formatting calls and
	  correcting DMA boundary errors, the third is for working around
	  problems in a particular version of IBM's ROM BIOS
	before the first call, ES:BX points at the original BIOS INT 13; DS:DX
	  also points there unless IO.SYS has installed a special filter for
	  hard disk reads (on systems with model byte FCh and BIOS date
	  "01/10/84" only), in which case it points at the special filter
	most DOS 3.2+ disk access is via the vector in DS:DX, although a few
	  functions are still invoked via an INT 13 instruction
	during Windows 3.1 startup this function seems to be used to
	  temporarily point DOS to a dummy handler in WDCTRL.386 which always
	  halts the system with a fatal error message.	If DS hasn't changed
	  on return from the function, Windows will display the error message
	  "Invalid DOS version".
	this is a dangerous security loophole for any virus-monitoring software
	  which does not trap this call ("INT13", "Nomenklatura", and many
	  Bulgarian viruses are known to use it to get the original ROM entry
	  point)
	the preloadable Novell DOS 7+ SECURITY.BIN driver $SECURE$ traps
	  this call.
BUG:	Novell DOS 7 IBMBIO.COM before 1995-05-08 trashed AX on return from
	  this function. VGACOPY by Thomas Mnkemeier's VGA Software GmbH
	  crashed due to this.	Later releases of Novell DOS 7 preserved the
	  contents of the AX register.

		ES:DI -> version signature ("4.01$".."4.04$" for 4.01..4.04)
	flags may be destroyed
Program: NLSFUNC 4.01+ is currently an independent project under
	  development by Matthias Paul. It is not yet publically available,
	  but as NLSFUNC 4.00 did, it will probably become available with
	  future DR-DOS releases.
Notes:	If BX <> 0EDCh on entry, DR-DOS NLSFUNC 4.01+ performs the standard
	  installation check (INT 2F/AX=1400h), and does not change ES:DI.
	DR DOS 5.0+ NLSFUNC 3.00+ returns CF set and AX=0001h, if AL was not
	  00h, FEh, or FFh on entry.
	NLSFUNC 4.01+ will use the ES:DI enhancement to check the driver
	  version and calculate displacements into the resident driver for
	  runtime updates of internal structures like the local NLS database
	  filespec, etc.
	If the returned ES points into the HMA (ES=FFFEh) care should be taken
	  to actually access the HMA while checking the version signature and
	  updating resident data (mutex with local A20 enable/disable).
	While previous issues of NLSFUNC installed under a multitasker,
	  DR-DOS NLSFUNC 4.01+ will actually adapt to work properly in this
	  environment.

Notes:	the Windows enhanced mode loader and Microsoft 286 DOS extender will
	  broadcast an INT 2F/AX=1605h call when initializing.	Any DOS device
	  driver or TSR can watch for this broadcast and return the appropriate
	  values.  If the driver or TSR returns CX <> 0, it is also its
	  responsibility to display an error message (however, Windows95 is
	  reported to load regardless of the returned CX).
	each handler must first chain to the prior INT 2F handler with
	  registers unchanged before processing the call
	if the handler requires local data on a per-VM basis, it must store the
	  returned ES:BX in the "next" field of a startup info structure and
	  return a pointer to that structure in ES:BX
	a single TSR may set the V86 mode enable/disable callback; if DS:SI is
	  already nonzero, the TSR must fail the initialization by setting CX
	  nonzero
	MSD checks for Windows 3.0 running in standard mode by testing whether
	  CX=FFFFh and other registers are unchanged on return
	Novell DOS v7.0 (Update 8 - Update 11) TASKMGR in multitasking mode
	  uses this broadcast, even if TASKMGR.INI sets WinPresent= to OFF
	Microsoft's EMM386.EXE for DOS 5+ when installed with the NOEMS option
	  changes its driver name from EMMQXXX0 to EMMXXXX0 while Windows is
	  active

	these functions are supported by the DOS 5+ kernel; DOSMGR contains
	  tables of instancing information for earlier versions of DOS
	see Geoff Chappell's book _DOS_Internals_ for additional discussions of
	  DOSMGR's behavior and instancing in general

INT 2F U - MS-DOS 7 kernel - SET SYSTEM.DAT (REGISTRY FILE) PATHNAME
	AX = 1614h
	ES:DI -> ASCIZ pathname to Windows95 SYSTEM.DAT
Return: AX = status

2F1615 - INT 2F - Windows95 - SAVE32.COM - INSTALLATION CHECK

INT 2F - Windows95 - SAVE32.COM - INSTALLATION CHECK
	AX = 1615h
Return: AX = 0000h if installed
	    BX = segment of resident code
Program: SAVE32.COM is a TSR included in the Windows95 distribution which
	  preserves the contents of 32-bit registers across invocations of
	  all of the hardware interrupt handlers (which, for some older BIOSes
	  and TSRs, do not properly preserve the high words of the 32-bit
	  registers)

2F1680 - INT 2F - MS Windows, DPMI, various - RELEASE CURRENT VIRTUAL MACHINE TIME-SLICE

INT 2F - MS Windows, DPMI, various - RELEASE CURRENT VIRTUAL MACHINE TIME-SLICE
	AX = 1680h
Return: AL = status
	    00h if the call is supported
	    80h (unchanged) if the call is not supported
Notes:	programs can use this function in idle loops to enhance performance
	  under multitaskers; this call is supported by MS Windows 3+, DOS 5+,
	  DPMI 1.0+, and in OS/2 2.0+ for multitasking DOS applications
	does not block the program; it just gives up the remainder of the time
	  slice
	should not be used by Windows-specific programs
	when called very often without intermediate screen output under
	  MS Windows 3.x, the VM will go into an idle-state and will not
	  receive the next slice before 8 seconds have elapsed. This time can
	  be changed in SYSTEM.INI through "IdleVMWakeUpTime=<seconds>".
	  Setting it to zero results in a long wait.
	this function has no effect under OS/2 2.10-4.0 if the DOS box has an
	  "Idle Sensitivity" setting of 100

2F1681 - INT 2F - MS Windows 3+ - BEGIN CRITICAL SECTION

INT 2F - MS Windows 3+ - BEGIN CRITICAL SECTION
	AX = 1681h
Notes:	used to prevent a task switch from occurring
	should be followed by an INT 2F/AX=1682h call as soon as possible
	nested calls are allowed, and must be followed by an appropriate number
	  of "end critical section" calls
	not supported in Windows/386 2.x. Get INDOS flag with INT 21/AH=34h and
	  increment by hand.
SeeAlso: AX=1682h,INT 15/AX=101Bh,INT 21/AH=34h

2F1682 - INT 2F - MS Windows 3+ - END CRITICAL SECTION

INT 2F - MS Windows 3+ - END CRITICAL SECTION
	AX = 1682h
Notes:	not supported in Windows/386 2.x.  Get InDOS flag with INT 21/AH=34h
	  and decrement by hand, taking care not to decrement InDOS flag
	  through zero

2F1683 - INT 2F - MS Windows 3+ - GET CURRENT VIRTUAL MACHINE ID

INT 2F - MS Windows 3+ - GET CURRENT VIRTUAL MACHINE ID
	AX = 1683h
Return: BX = current virtual machine (VM) ID
Notes:	Windows itself currently runs in VM 1, but this can't be relied upon
	VM IDs are reused when VMs are destroyed
	an ID of 0 will never be returned

2F1684 - INT 2F - MS Windows - GET DEVICE API ENTRY POINT

INT 2F - MS Windows - GET DEVICE API ENTRY POINT
	AX = 1684h
	BX = virtual device (VxD) ID (see #02642)
	ES:DI = 0000h:0000h
Return: ES:DI -> VxD API entry point, or 0:0 if the VxD does not support an API
Note:	some Windows enhanced-mode virtual devices provide services that
	  applications can access.  For example, the Virtual Display Device
	  (VDD) provides an API used in turn by WINOLDAP.

Notes:	The high bit of the VxD ID is reserved for future use. Originally,
	  the next 10 bits were the OEM number which was assigned by Microsoft,
	  and the low 5 bits were the device number.  Currently, Microsoft
	  assigns VxD IDs individually for each driver; send blank email to
	  vxdid@microsoft.com for more information.
	"CallOut"=Y indicates that the VxD uses the INT 2F/AX=1607h/BX=VxDID
	  device callout interface; "PM" and "V86" indicate whether the VxD
	  provides an API entry point in protected mode and Virtual-86 mode
	  (e.g. DOS boxes)

	  advance in execution for so long as SHELLB provides PSCs from its
	  workspace.
Note:	The PSCs are planted in SHELLB workspace by SHELLC, the user
	  menu interface.  The final PSC of a sequence is finished with a
	  GOTO COMMON, which causes a loop back in the batch file which called
	  SHELLC so as to execute SHELLC again.	 The check on batch file name
	  permits PSCs to CALL nested batch files while PSCs are still stacked
	  up for subsequent execution.

		either short jump (EBh XXh) followed by three NOPs or
		  far jump (EAh XXXX:XXXX) to a program which has hooked itself
		  into the XMS driver chain
Note:	to hook into the XMS driver chain, a program should follow the chain of
	  far jumps until it reaches the short jump of the driver at the end
	  of the chain; this short jump is to be replaced with a far jump to
	  the new handler's entry point, which should contain a short jump
	  followed by three NOPs.  The new handler must return to the address
	  pointed at by the short jump which was overwritten.  Using this
	  method, the new handler becomes the first to see every XMS request.

2F4A06 - INT 2F CU - DOS 5+ - DOS SUPERVISOR "REBOOT PANEL" - ADJUST MEMORY SIZE

INT 2F CU - DOS 5+ - DOS SUPERVISOR "REBOOT PANEL" - ADJUST MEMORY SIZE
	AX = 4A06h
	DX = segment following last byte of conventional memory
Return: DX = segment following last byte of memory available for use by DOS
Desc:	used to override the default memory size when booting diskless
	  workstations
Notes:	called by MS-DOS 5+ IO.SYS and DR DOS 6.0+ IBMBIO.OCM startup code if
	  the signature "RPL" is present three bytes beyond the INT 2F handler;
	  this call overrides the value returned by INT 12
	hooked by RPL code at the top of memory to protect itself from being
	  overwritten; DOS builds a memory block with owner = 0008h and name
	  "RPL" which must be freed by the RPL code when it is done.
	  Under DR DOS, it is sufficient to set the owner field of the MCB to
	  0000h.
	In addition to the test for "RPL", DR PalmDOS (since 1992/08/25),
	  DR DOS 6.0 "Business update March 1993", DR DOS "Panther" and
	  "StarTrek", and Novell DOS 7+ also check for a "RPLOADER" signature.
	  If this 2nd signature is found, IBMBIO.COM will store the INT 2Fh
	  vector for later use after the BIOS init, when at several points it
	  directly calls the RPLOADER via an emulated INT 2Fh with
	  AX=12FFh/BX=5/CX=0/DX=1 and a phase code 1, 2 or 3 on the stack.
	  This permits the RPLOADER to keep track of the initialization
	  process and clean or fix up anything it wishes.  The "phase 1"
	  broadcast is issued after the BIOS init code and data have been
	  relocated (e.g. into the HMA), "phase 2" gets issued immediately
	  before the CONFIG.SYS processing begins and the DOS code and data
	  are relocated, and the closing "phase 3" happens to permit any
	  final tidy ups before the memory manager gets acknowledgement of
	  completion.

	  PC-Cache v8.0 and recent versions of the Norton Caches
	the internal name for SMARTDRV is "BAMBI", hence the magic "BABE".
	if DBLSPACE.BIN is installed but SMARTDRV has not yet been installed,
	  then calls of this function with CX<>EBABh on entry cause
	  DBLSPACE.BIN to display the error message
	  "Cannot run SMARTDrive 4.0 with DoubleSpace" and abort the caller
	  with INT 21/AX=4C00h
	Since the Novell DOS 7 - DR-DOS 7.03 NWCACHE supports a similar 
	  install check at this function, but the returned registers
	  contain different data, the caller must take the returned AX value
	  into account to ensure proper interpretation of the returned info.
	  The caller should ensure CX <> 0EDCh to avoid any interaction
	  with the NWCACHE and COMMAND.COM special case of CX=0EDCh.
	  Although this is an install check, NWCACHE always flushes delayed
	  writes to disk, when calling this function with CX<>0EDCh or while
	  /FLUSH:ON is active, but this is nothing to rely upon. The reason
	  for this could be to get more accurate statistics, while SMARTDRV
	  just takes a on-the-fly snapshot of the statistic vars.
	The private NWCACHE/NLCACHE install check INT2Fh/D8C0h does not flush
	  to disk, and therefore can be used by callers that must ensure
	  the buffers aren't flushed on this function (e.g. alternative
	  command shells may need this to make their "flush before prompt"
	  feature configurable).
	The NWCACHE 0EDCh special case will most probably vanish with
	  future issues of NWCACHE (2.0+).
	SMARTDRV v3.x had a completely different API using IOCTL calls, which
	  was also supported by the Norton Caches
BUG:	Although DS and ES registers are listed as unmodified, some
	  releases of SMARTDRV seem to trash the DS register, at least the
	  MS-DOS 6.2+ KEYB takes care to preserve the DS register when calling
	  this function.

Notes:	SMARTDRV 4.0+ uses a similar installation check on this function but
	  returns different data.  To ensure proper interpretation of
	  the returned values, the caller must check the returned magic
	  value in AX. Since SMARTDRV may also alter DI:SI (and possibly
	  DS), the caller should take care of this, too.
	The Novell DOS / DR-DOS 7.x COMMAND.COM invokes this function with
	  CX=0EDCh, which causes NWCACHE to flush any delayed writes before
	  returning the normal register values if it is configured to flush
	  writes before returning to the DOS prompt (/FLUSH:ON); however, if
	  /FLUSH:OFF, this function becomes a NOP with CX=0EDCh.
	Note that for this function the 0EDCh special case may vanish with
	  future issues of NWCACHE (2.0+), and the function would then always
	  do the normal install check, and not flush the cache.

Notes:	If the read cache is off, reads will not be cached, but writes will

	this function is also supported by PC-Cache v8.0.
	SMARTDRV flushes the cache if sub-functions 02h or 04h have been
	  called to disable read or write caching.
	On calling this function, NWCACHE flushes any delayed writes,
	  but you should not rely on this, since this behavior may vanish
	  in future versions.
BUG:	The MS-DOS 6.20+ SCANDISK disables a SMARTDRV 4+ compatible cache
	  for the drive it is about to process.  However, at least when the
	  cache loaded is NWCACHE, the cache will still remain disabled for
	  this drive after SCANDISK has finished.  The reason for this behavior
	  is not yet known. The workaround is to re-enable with the
	  NWCACHE d:+ syntax afterwards, where d: is the corresponding
	  drive letter.

Return: ES:BX -> callback info structure (see #02817) or 0000h:0000h
Notes:	called by the task switcher
	this function is hooked by clients which require notification of task
	  switcher activities; the call must first be passed on to the prior
	  handler with registers unchanged using a simulated interrupt.	 On
	  return, the client must build a callback info structure and store
	  the returned ES:BX in the "next" field, then return the address of
	  its own callback info structure.
	a client program must add itself to the notification chain if it
	  provides services to other programs; before terminating, it must
	  remove itself from the chain by calling the task switcher's entry
	  point with AX=0005h (see #02819)
	the task switcher entry point should not be saved, as it is subject to
	  change and will be provided on any notification call
	the Windows 3.1 Standard Mode supports this API

	ES:DI -> task switcher entry point (see #02819)
Notes:	function 0000h is generally called by the program which controls or
	  invokes the task switcher, rather than by the task switcher itself;
	  the entry point supplied to this function is not necessarily the
	  entry point to the task switcher itself, and may be 0000h:0000h.  If
	  any client indicates that loading is not possible, all clients will
	  be called with function 0007h; thus it is possible for a client to
	  receive a termination notice without a corresponding initialization
	  notice.
	except for functions 0002h and 0003h, the notification handler is
	  called with interrupts enabled and may make any INT 21h function
	  call; interrupts must not be enabled in functions 0002h and 0003h
	function 0007h may be called with ES:DI = 0000h:0000h if the entry
	  point is no longer valid

2F5500 - INT 2F U - DOS 5+ - COMMAND.COM INTERFACE

INT 2F U - DOS 5+ - COMMAND.COM INTERFACE
	AX = 5500h
Return: AX = 0000h if an instance of COMMAND.COM is already running
	DS:SI -> entry point table
Notes:	used to access the shareable portion of COMMAND.COM, which may have
	  been moved into the HMA; only the primary COMMAND.COM retains this
	  portion
	procedures called from a dispatcher in COMMAND's resident portion;
	  most assume that the segment address of the resident portion is on
	  the stack and are thus not of general use
	DR PalmDOS up to DR-DOS 7.03 COMMAND.COM do not support this call.
	When loading the default command processor (no SHELL= directive in
	  CONFIG.SYS), MS-DOS 6.0-6.22 IO.SYS & PC DOS 6.1-2000 IBMBIO.COM
	  check a signature (see #04099) in the COMMAND.COM file image to test
	  if it is actually their own shell and has the correct version, before
	  they will launch it. If the signature is not found, the message
	  "Invalid COMMAND.COM" will be displayed. This test seems to have
	  vanished with MS-DOS 7+, as it uses an .EXE style file format.
	In addition to this, the MS-DOS/PC DOS COMMAND.COM checks the version
	  of the underlaying OS to see if it is their own. Hence, the
	  PC DOS 6.1 (and by SETVER version faking also the PC DOS 7 and 2000)
	  COMMAND.COM also run on Novell DOS 7 - DR DOS 7.03, which all
	  identify themselves as DOS API level 6.0 and IBM OEM (not yet tested
	  as primary shell).  PC DOS 5.0 COMMAND.COM should run on DR PalmDOS
	  (untested).
	The MS-DOS 7+ COMMAND.COM seems to no longer perform this kind of
	  version check any more, which can cause a serious deadlock situation
	  on a multi-boot system with DR-DOS installed, when the MS-DOS 7+
	  COMMAND.COM is placed in C:\. When IBMBIO.COM attempts to load the
	  MS-DOS 7+ COMMAND.COM as a primary shell under DR-OpenDOS 7.02 to
	  DR-DOS 7.03 no error message will be displayed by COMMAND.COM, but
	  the machine will just hang. To defuse this situation, DR-DOS 7.02+
	  IBMBIO.COM was changed to still scan for a SHELL= directive in
	  [D]CONFIG.SYS even in F5-mode. For maximum safety, the MS-DOS 7
	  COMMAND.COM should be moved from C:\ to C:\WINDOWS\COMMAND\
	  and a DCONFIG.SYS file should be created containing for example
	  SHELL=C:\DRDOS\COMMAND.COM instead. If a MS-DOS CONFIG.SYS file
	  exists, it should contain a SHELL=C:\WINDOWS\COMMAND\COMMAND.COM
	  directive. (If no shell can be found at all, DR-DOS IBMBIO.COM would
	  display a prompt to enter the proper path to COMMAND.COM).
	The DR-OpenDOS 7.02+ COMMAND.COM is designed to also run on 3rd party
	  operating systems like MS-DOS/PC DOS 3.31+, Windows 9x, and in DOS
	  boxes of OS/2, Windows NT and 2000, and will for example also take
	  advantage of long filenames.

Format of Microsoft COMMAND.COM file image signature:

 03h	BYTE	version
		bits 7-4: major version
		bits 3-0: minor version code

		  64h for MS-DOS 6.20, Japanese MS-DOS 6.2, Hangeul MS-DOS 6.2;
		  66h for MS-DOS 6.22, PRC (Chinese) MS-DOS 6.22;
		  70h for PC DOS 7, PC DOS 7 Y2K edition )
Notes:	Since DR DOS 6.0+, MS-DOS 7.0+, PTS-DOS, S/DOS, 4DOS/NDOS use an .EXE
	  style shell file format, this signature is not met by any release of
	  these shells. DR DOS 3.31-5.0 used a different jump (E8h) at offset
	  00h.
	Older releases of MS-DOS/PC DOS all had a jump (E9h) at offset 00h, but
	  other values at offset 03h. For reference here is a list of the
	  values for some of these older shells:
	    00h for PC DOS 1.10, Olivetti DOS 2.11, MS-DOS 5.0,
		  Russian MS-DOS 5.0
	    1Eh for MS-DOS 4.01
	    BAh for PC DOS 3.10, 3.20, MS-DOS 3.30

Notes:	INTERLNK was derived from Sewell Development Corporation's FASTLYNX.
	Some Microsoft software explicitly clears the BH and CX registers
	  before calling this function.
BUG:	reportedly, the MS-DOS INTERSRV program (though not INTERLNK) causes
	  serious FAT corruption and data loss when run under Novell DOS 7.
	  INTERSRV apparently checks for DR-DOS by testing the "OS"
	  environment variable for the value "DRDOS", which is no longer
	  correct for PalmDOS, Novell DOS, or OpenDOS.  A workaround may be
	  to explicitly set the OS variable to "DRDOS".

2F7A20BX0000 - INT 2F - Novell NetWare - Adv NetWare 4.0 DOS Requester - GET VLM CALL ADDRESS

	BX = 0000h
Return: AX = 0000h on success (installed)
	    ES:BX -> far call address for DOS Requester (see #02859)
Notes:	the DOS Requester replaces the NetWare Shell (ANETx, NETx) on
	  NetWare LAN's as of the release of Advanced NetWare 4.0 (1993).  It
	  is backward compatible with NetWare 2.1x through 3.11 servers as
	  well.	 Note that there was a NetWare 4.0 in the early 1980's, which
	  can cause confusion.
	this call is used as the installation check by VLM.EXE, which is the
	  loader for all the modules of the DOS Requester
	.VLMs are standard old .EXE format executables whose normal entry point
	  merely terminates to prevent loading from the command line (Novell's
	  VLMs all return errorlevel 6).  The real entry point is found by
	  looking at the VLM header at the beginning of the load image
	  (see #02862)

INT 2F - Arabic/Hebrew DOS 5.0???+ - GET CURRENT FONTPAGE
	AX = AD41h
	(CX = 0000h)
Return: CX = current fontpage
Notes:	Called by Arabic/Hebrew MS-DOS 5.0 CODEPAGE.COM immediately before
	  a call to INT21h/6601h to get the current codepage.
	The function is probably implemented in the ARABIC.COM/HEBREW.COM
	  driver.
	The CX = 0 on call is not actually a requirement, but it should be
	  initialized this way to receive a fontpage 0 if ARABIC.COM/
	  HEBREW.COM is not loaded. A fontpage 0 indicated no fontpage
	  support. At least this is what CODEPAGE.COM assumes (by using
	  the CX=0 init status of a .COM program, when not being loaded
	  in DEBUG.)
	Some European clones have code page 850 as their hardware font instead
	  of code page 437

Notes:	This call provides a mechanism for TSRs to install permanent

Return: DS:SI buffer updated
	  if length byte is nonzero, the following bytes contain the uppercase
	  internal command to execute and the command line buffer contains the
	  command's parameters (the first DS:[SI] bytes are ignored)
Notes:	this call requests execution of the command which a previous call to
	  AX=AE00h indicated was resident
	APPEND hooks this call
BUG:	Novell DOS 7.0's COMMAND.COM (prior to Update 12) will attempt to run
	  a disk program with the indicated name even if the returned length
	  byte is zero, because the register used to flag this case is
	  clobbered without first checking it.	The workaround is to set the
	  command name buffer to "REM" followed by enough blanks to pad out
	  the original command's length, which will also work with MS-DOS 6.

Note:	if the next INT 21h call (and ONLY the next) is function 3Dh, 43h, or

	The entries for the color table are in char/attrib form.  Every two
	  entries form a pair which is alternated between 68 times a minute.
	  The first half of the table is for color videos, the second mono.
	  Within each half, the first half is for the safe chars, and the
	  second for the critical chars.

Format of HEART.COM buffer:
Offset	Size	Description	(Table 03088)
 00h  8 WORDs	table of colors/attributes (refer to notes above)
 10h	BYTE	flags
		bit 0: program is in critical section, so flash double
		      exclamation mark
		bit 1: program is in safe code, so flash the heart character
 11h	WORD	position of heartbeat on screen, normally 009Eh (last column
		of second line)

Notes:	up to three handlers can be defined by separate calls to this function,
	  each with a different combination of shift states in the call mask;
	  calling this function again with a call mask of 0000h undefines the
	  specified handler (official documentation); specifying the same
	  call mask and an address of 0000h:0000h undefines the handler (real

	AX = 006Dh 'm'
Return: ES:DI -> Microsoft version number of resident driver (see #03187)
Notes:	also supported by Logitech, Mouse Systems, Kraft, and Genius mouse
	  drivers
	the Mouse Systems 7.01 and Genius Mouse 9.06 drivers report their
	  Microsoft version as 7.00 even though they do not support any of the
	  functions from 0025h through 002Dh supported by the MS 7.00 driver
	  (the Genius Mouse driver supports function 0026h, but it differs
	  from the Microsoft function)
	the TRUEDOX 4.01 driver reports its version as 6.26 through this call,
	  but as 6.24 through AX=0024h
	There seems to be no reliable method to distinguish MS MOUSE before
	  3.00 from mouse drivers of other vendors.
	Some releases of the MS MOUSE 6.00 erroneously return 6.01 instead of
	  their true version number.  In this case, a DI value of 01ABh can
	  be used to still detect a 6.00 driver.
	For returned versions 6.02+, INT 33/AX=0024h should be used to retrieve
	  more accurate version data. 
	True MS MOUSE drivers can also be identified by magic numbers in
	  their copyright message, stored in the driver's segment (ES).
	  These can be found by scanning the first 2 Kb of the mouse 
	  driver's segment for a string like: [new since 7.00+] 
	  "** This is Copyright 1983[-19xx] Microsoft ***" with the
	  magic number stored one byte after the signature string.

 E2h	round TOS and R1 to double precision, compare, pop twice
	  returns AX=8087 status word, FLAGS=8087 condition bits
	Note: buggy in TPas5.5, because it sets the 8087 precision control
	  field to the undocumented value 01h; this results in actually
	  rounding to single precision

41 - INT 41 - SYSTEM DATA - HARD DISK 0 PARAMETER TABLE ADDRESS [NOT A VECTOR!]

INT 41 - SYSTEM DATA - HARD DISK 0 PARAMETER TABLE ADDRESS [NOT A VECTOR!]
Notes:	the default parameter table array is located at F000h:E401h in 100%
	  compatible BIOSes; the pointer may be overridden by the hard disk
	  controller's BIOS to support drive formats unknown to the ROM BIOS
	not used by some PS/2 models
	BIOSes which support four hard drives may store the parameter tables
	  for drives 81h-83h immediately following the parameter table pointed
	  at by INT 41, with a separate copy of the drive 81h table for INT 46.
	  The check for such an arrangement is to test whether INT 46 points
	  somewhere other than exactly 16 bytes past INT 41, and the sixteen
	  bytes starting at offset 10h from INT 41 are identical to the sixteen
	  bytes pointed at by INT 46
	another arrangement for BIOSes which support four IDE drives is to have
	  four tables pointed at by INT 41 in the order primary master,
	  primary slave, secondary master, and secondary slave, in which case
	  (for example) a system with only primary master and secondary master
	  will have valid tables at offsets 00h and 20h, with garbage (but
	  sectors-per-track = 00h) at offsets 10h and 30h

	AL = scan code???
Note:	This interrupt may be un-initialized (0000h:0000h) on old machines.
	  This should be checked before calling or hooking this vector.
	MS-DOS/PC DOS 3.3x-4.x KEYB hooked the INT 48h handler. For AL <= 80h
	  it checked that either ALT and neither CTRL key was pressed,
	  and in that case, it cleared the CTRL flag in the BIOS variable at
	  0040:0017h and stored its contents in an internal variable,
	  before continuing with the previous (non-zero) INT 48h handler.

Notes:	[1] four of the keys can have differing scan codes, depending on the
	  actual keyboard; the BIOS accepts either scan code ("normal": 2Fh,
	  30h, 5Ah, 64h; "alternate": 2Dh,3Fh,5Eh,5Fh) for any of these keys
	[2] Shift-Print invokes INT 5E for a screen dump; the PRTSCRN.DEV
	  device driver also supports Alt-Print, Ctrl-Print, Shift-Alt-Print,
	  and Shift-Ctrl-Print for dumping graphics in various permutations
	[3] BRK/PAUS invokes INT 5C for a pause, then stuffs 0100h into the
	  keyboard buffer
	[4] Shift-BRK/PAUS invokes INT 5D for the Break, then stuffs 0000h
	  into the keyboard buffer; MS-DOS hooks INT 5D to keep the 0000h from
	  appearing in the keyboard buffer
	[5] on the TI Pro, one enters an arbitrary character slightly
	  differently than on a standard PC: exactly three numberpad digits
	  must be pressed (using leading zeros for codes less than 100), and
	  the key for the requested code is inserted into the keyboard buffer
	  immediately on pressing the third key.  The Alt key may be released
	  and re-pressed arbitrarily often between digits without affecting
	  the Alt-digit-digit-digit sequence.
	scan codes with bit 7 set are not key releases, but rather
	  auto-repeated keystrokes, which the BIOS only places into the
	  keyboard buffer if the buffer is empty at the time (thus avoiding
	  typeahead of repeated keystrokes faster than they can be processed)

5B - INT 5B C - TI Professional PC - KEYBOARD MAPPING HOOK

INT 5B C - TI Professional PC - KEYBOARD MAPPING HOOK
	CF set
	AH = shift state (see #03247)
	AL = scan code (see #03214)
Return:	BX, CX, DI, ES may be destroyed
	various return methods are supported:
	    IRET, AX unchanged: process keystroke normally
	    IRET, AL = FFh: discard keystroke
	    IRET, AX changed: process modified keystroke
	    chain to old INT 5B: allow other handlers to look at (possibly
		  modified) keystroke in AX
	    RETF 2, CF clear: place returned AX into keyboard buffer without
		  any further processing
Notes:	invoked by the keyboard ISR, and used to remap the keyboard
	if CF is clear on entry, some other handler has processed the
	  keystroke and the current handler should not modify it, instead
	  performing a RETF 2 or IRET (after clearing CF on the stack)
	when requesting that a value be placed directly into the keyboard
	  buffer, AL and AH may not *both* be nonzero (the TI does not
	  return scan codes as part of the key code for non-extended keys)

5C - INT 5C - NetBIOS INTERFACE

INT 5C - NetBIOS INTERFACE
	ES:BX -> network control block (NCB) (see #03249)
Return: AL = status (see #03248)
Program: NetBIOS was developed by Sytek, Inc. in 1984 as a high-level
	  programming interface to the IBM PC Network; the first implementation
	  was a ROM BIOS extension on Sytek's PCnet LAN adapter card, but many
	  current networks support NetBIOS as the session layer.
Notes:	The Sytek PCnet card uses DMA 3.
	On some machines this vector is not initialized (e.g. Epson machines).
	  Hence this interrupt should only be called or hooked if the vector
	  does not point to 0000h:0000h.

60 - INT 60 - TCPDRV 2.01 - TCP/IP Application Binary Interface (ABI)

INT 60 - TCPDRV 2.01 - TCP/IP Application Binary Interface (ABI)
Note:	The handler for the interrupt will start with a 2-byte NEAR jump
	  instruction, followed by the ASCIZ signature string "TCP DRVR".
	To find the interrupt being used by the driver, an application
	  should scan through interrupt vectors 60h to 7Fh until it finds
	  one with the "TCP DRVR" string.
	This specification is being proposed by Peter R. Tattam from the
	  University of Tasmania.

INT 60 U - INTRSPY/CMDSPY v1.0 only - API
Program: INTRSPY is a script-driven debugger included with the book

InstallCheck:	determine that a) the handler is an IRET instruction, and
	  b) the signature 0Dh "INTRSPY vN.NN" immediately precedes the handler
Notes:	INTRSPY will hook the first available interrupt in the range 60h-67h.
	If INTRSPY is installed, the DWORD immediately after the IRET stores
	  its entry point (see #03275)
	INTRSPY v2.0 (included with the second edition of the book) no longer

Program: MDEBUG is a shareware memory-resident debugging tool by Bernd
	  Schemmer, including a memory monitor, an interpreter, and a
	  disassembler
Notes:	MDEBUG uses INT 60 by default, but may be directed to any of INT 60
	  through INT 67; the interrupt handler is preceded by the signature
	  "USERINT" and is not chained
	if DS:SI points at a null byte, MDEBUG will prompt for a password if
	  passwords are active; enough stack space must be provided for an
	  INT 10h call (which MDEBUG uses while prompting for the password)
SeeAlso: AH=02h"MDEBUG"
