Does any one have experience on Tyan S1662 Pentium Pro motherboard (200 MHz)?
I bought one this board a week ago, it crashes every 10 minutes for unknown
reason (core dump did not report where it crashed) and the core dump is
attached at the end.
All components (memory, video card) are working on an ASUS motherboard
(also 200MHz CPU). Since trap reports that page fault, but the memory simms
are good, so I disabled both internal and external caches, the crashing still
happenes every 10 minutes.
Does this mean that it is a bad motherboard (bad MMU chip) or bad CPU or
there are some other problems?
thanks for giving any information,
