Notes:	reportedly supported by RM Nimbus MS-DOS 3.3 kernel
	this function is called by DOSMGR when AX=1607h/BX=0015h is not

Return: CX = 0000h if okay for Windows to load
	CX = FFFFh (other registers unchanged) if Windows 3.0 in standard mode
	CX <> 0 if Windows should not load
	ES:BX -> startup info structure (see #02631)
	DS:SI -> virtual86 mode enable/disable callback or 0000h:0000h
	      (see #02634)
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

 0Ch  N DWORDs	"SRC_PAGE" physical addresses of the pages
		00000000h = end of table
Note:	EMM386.EXE sets the first pointer to the start of the device driver

Return: ES:DI -> TSR information structure (see #02638)
Desc:	this call allows Windows-aware TSRs to make themselves known to

	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

	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

	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)

	  and save/restore the video memory itself.
