Int 96  U - Kill.com, Qkill.com - Pop Up                                   [U]

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]
