I can get the interrupt installed and >it runs, but when the interrupt terminates, it locks the keyboard up. You didn't say what interrupt you were using.. I assume it's has to do with the keyboard interrupt, are you just hooking into the interrupt or are you attempting to service it your self and forget the other guys down the line. With out knowing more I would say you are not issuing the Non-specific Interrupt Clear to the 8059 but that about all I can say. Be more specific about what you are tring to do here.. Interrupts on the PC machines are screwed up at best (for those of you that don't think so, try messing with the EGA interrupt). Jack Hudler -- See above (214)661-8960
