Return: AX = 9669h
Program: ISR (Interrupt Service Reflector) is a TSR by Rich Bono which permits
	  a program to provide hardware interrupt handlers even while being
	  debugged with a debugger that swaps interrupt vectors during
	  debugging.
Note:	the interrupt vector which is to be reflected is set at installation
	  time and cannot be changed

InstallCheck:	test for the signature "SYSV" immediately before the interrupt
	  handler
