Ummm...I'm not sure that would be safe. Interrupts below 20h are reserved
for BIOS, and even then, several interrupts are used by DOS(20, 21, 33,
etc). You might try picking random interrupt numbers above 21h using this
code:

Mov AX,35(interrupt)h
Int 21h

If ES(the interrupt's code segment) and BX(the interrupt's origin) are 0,
you've found a free interrupt.
