I've installed Windows 2000 SP2 on an HP Vectra XU 5/90c with dual 133
MHz Pentium-1 processors and 112 MB of RAM. It is running on a SCSI-2
drive using the built-in AMD PCscsi BIOS and controller. The graphics
controller is a Diamond Stealth 3D 2000 PCI card using the S3 Virge
chipset.
My problem is that at seemingly random intervals, the computer will
lock up. When it does lock up, the PS/2 keyboard and PS/2 mouse stop
working and the video stops updating, but disk activity continues and
the OS seems to complete whatever task it was working on. The lockups
occur sometimes during boot-up, and sometimes after several hours of
use. Here's the kicker though -- the lockups only occur when using 2
processors. I'm currently using the MPS Multiprocessor HAL in Windows
2000. If I switch to the MPS Uniprocessor HAL, the crashes vanish.
To troubleshoot, I've tried:
- Swapping in a newer and higher-wattage power supply;
- Switching CPUs with other known working CPUs of the same type;
- Made sure both CPUs are of same stepping #;
- Installing Windows 2000 SP2 on an IDE drive instead;
- Removing all ISA cards in case of a mis(un)reported IRQ conflict;
- Freeing up all IRQs in BIOS;
- Removing other drives and peripherals
Needless to say, none of those worked, or I wouldn't be posting now.
Does anyone have any clue as to what could be causing my trouble?
Thanks,
TK
