Perhaps I did it wrong. I set the IRQ to 1 (Keyboard). The keyboard did not
work when this kernel was in place and it crashed after less than 1 hour. I
went to the machine and pounded on the keyboard, but no oops message. I
might re-try this by hooking IRQ 12 for the PS/2 mouse. At least I could use
the keyboard then....

There does not seem to be a discernible pattern of times or activities.

I have not tried this. On the next crash I will test it.

One machine with a kernel compiled Uni-Processor would still exhibit the
lock-ups with the 2.2.14 series. I have never tried physically removing a
processor to see if the problem went away.

FWIW, I have a 3rd machine that has been running NT 4.0 with the same MOBO
that hasn't crashed in a year.

Intel 440BX
