Hi, We have an AT&T PC6300 that occasionally gives illegal interrupts 0D and 0F at bootup (just after the message about optional ROM found at C800). According to my recollection, interrupts 08-0F are the vectored interrupts on the PC/XT. Does anybody happen to know what is connected to the interrupt controller at those addresses? --Bill

I got illegal interrupts with Xenix from a bus mouse after I had just run MS-DOS. Was this with Dos or another OS. Also, what hardware's on the system? It may be some driver interaction like the mouse that Xenix couldn't handle.
