I'm working on a programming project with some friends and one of the things we're doing is hooking the keyboard interrupt (handling the keyboard ourselves is a requirement of what we're doing). On the 5160, trapping int 09h/IRQ 1 works as expected. On a 5155 we're using for testing, it does not -- IRQ1 never seems to fire (ie. keyboard is dead).
Before I delve much further into this, was there a fundamental difference between the 5160 and 5155 in terms of keyboard handling in the hardware and/or BIOS? If so, what is the difference? Both the 5155 and 5160 use variants of the same motherboard, and although the 5155 keyboard uses an RJ11 to connect to the front, in back it's a normal 5-pin DIN and, I'm assuming, XT signaling.
