Motherboard is a SOYO SY-5SSM and I recently upgraded it with the latest BIOS off the manufacturer's website.
BIOS Date: 12/16/99
BIOS Type: Award Modular BIOS v4.51PG
BIOS ID: 12/16/1999-SiS-530-2A5IMS29C-00
BIOS Eval: SSM-2DB1
Chipset: SiS 530 rev 2
Superio: ITE 8661/SiS 6801 rev 2 found at port 279h
I tried to installed Win XP and it fails every time. After the first step of verifying and copying files from the installation CD to the hard drive (WD Caviar 120GB), Win XP restarts, displays the splash screen and reboots, the same three steps over and over and over again. Only a video card and a CD ROM are connected to the motherboard.
I found information related to this problem that was posted by other people on a website forum. SOYO's tech support stated to them that the problem is in the BIOS and that the motherboard can only run win95, 98, 98SE, NT, but not XP and not ME... It doesn't make sense since NT and XP are similar OS's.
Things that I've tried:
Use different memory sticks
Use a different hard drive
Use a different CD ROM
Use a different power supply
Use a different video card
Use mobo's onboard video
Disable ACPI in BIOS
Disable Video BIOS Shadow
Disable System BIOS Cache
Disable CPU to PCI Write Buffer
If the problem is in the BIOS, which option is the best?
Use another Award Bios from a similar SOYO motherboard
Find a patch for the current Award Bios
Crossflash to a AMI Bios and patch it
Thanks for the help.
