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)

	  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

	    0008h Text screen dump to ansi file
Return: nothing
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
	  safe to do so, thus the author recommends putting a 60 ms delay
	  after this call

Return: AL = FFh if installed
Program: REDVIEW is a public-domain TSR by Alexandr Novy and Petr Horak which
	  copies data sent to standard output to standard error when the
	  former has been redirected to a file, thus allowing the data to
	  be seen on the screen at the same time it is captured in a file

Call DVeop entry point with:

Return: AX = status

		ES:DI -> chaining address
	BX,CX,DX destroyed
Notes:	the callback function is called with a simulated interrupt when the
	  DESQview window containing it is closed; it should perform all
	  necessary cleanup and then perform a FAR jump to the chaining address
	  or an IRET if the chaining address is 0000h:0000h
	if the program wishes to remove itself before the window is closed, it
	  should call the DVeop entry point with the previously returned
	  chaining address and ignore the returned chaining address.

	for v1.00, function 0003h allocates common memory, which the caller
	  must deallocate after reading the process information; only the
	  currently used records are placed in the buffer
	for v1.10+, function 0003h merely returns a pointer to the internal
	  array of process information; the caller should make a copy of the
	  array while inside a critical section (see INT 15/AX=101Bh).	Only
	  those records with bit 7 of the first byte set are valid.

96 - INT 96 U - KILL.COM, QKILL.COM - POP UP

INT 96 U - KILL.COM, QKILL.COM - POP UP
Program: KILL.COM is a TSR utility that allows you to terminate programs
	 by calling INT 21/AH=4Ch or reboot the computer (author unknown);
	 QKILL.COM is a modification of KILL.COM by Solar Designer that
	 supports QEMM's Quick Boot feature
Notes:	This interrupt is intercepted but not chained by KILL.COM; it is never
	  called by KILL.COM itself. It points into the middle of KILL.COM's
	  INT 09 handler and assumes specific values have been placed on the
	  stack (thus it can't be called as an interrupt).
	To invoke KILL, use the following code:
		pushf
		push cs
		push offset $+0Dh
		push ax
		push es
		push 0
		pop  es
		jmp  dword ptr es:[96h*4]
