A friend of mine is having some system problem. Not sure if it is hardware or software related. He has

Shuttle XPC G4300
AMD Athlon XP 2400+ 266 MHz FSB
S3 Unichrome
256MB PC 3200
Drive bay 1: 80 GB SATA 7200 RPM
Drive bay 2: no drive
52x CD-RW / 16X DVD
On board 5.1 Sound w/SPDIF In/Out
56K PCI modem
Logitech Ultra KB8 Mouse combo
Parallel Printer port
No wireless
No floppy
XP home
Works suite
Open office

He bought his system directly from Shuttle about 10 days ago. It ran well for the first few days. Then he put Open office and added a scanner. Couple days later his computer started rebooting automatically. Won’t go past the Microsoft bootup screen. When tried to go to safemode, the system hung on MPU.sys.
I played around with his bios and nothing worked. Tried to boot up from his Shuttle XP recovery disk and it can’t find the hard drive. Shuttle website says to download the RAID driver and put it on a floppy disk and install during XP recovery. But the problem is my friend does not have a floppy disk drive.
I integrated his recovery disk with the RAID drivers (viasraid.sys etc) and made a new boot CD. It went through hardware inspection, loading files etc and reached “examining 76534 MB drive on id0 on viasraid...”. about an hour later it said to push any key to restart windows and then the reboot cycle started all over again. I tried it one more time and it crashed after examining HD.

Anybody has any idea how to fix this? I found that having to load the raid drivers before booting up from a CD really complicates the issue (at least for me).

Thanks!

mup.sys

There is nothing wrong with mup.sys if you see it on the screen. That means it has loaded succesfully. The problem is with your BIOS, the ESCD is corrupt. Re flash your BIOS and all should be good. :grinthumb
