I have an AT clone that runs at 12MHz;  unfortunately, I think the bus
speed also runs at that rate.  I've tried to install a Western Digital
hard disk controller WD-1003-WA2 on my motherboard, but I'd get write errors 
on my hard disk which end up corrupting the file I was trying to access.
I also have an NCL controller which runs fine at 12MHz, however this controller
doesn't seem to run Xenix.  I can never get pass the Xenix installation;
as soon as it tries to scan the hard disk (an ST 251-1)  for bad sectors,
Xenix belches "PANIC TRAP", displays the contents of the 80286 registers,
and then dies.

This is getting mighty aggravating.  Can someone please recommend to me
a disk controller card that will operate at 12MHz, and will run Xenix?
