--------U-96---------------------------------
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]
