Alot of PC keyboards have a switch on the bottom to select it as a XT
or an AT style keyboard. I've seen machine lock up under DOS or XENIX
sometimes if this switch changes settings while the machine is running.
The 8042 goes out to lunch sometimes from this. I've seen keyboards
where the switch gets bumped into an in between position, the machine 
powers up and runs fine until the keyboard gets shifted a little bit...
