Your not using the right install CDs. You have an AMD 64-Bit chip so
you can't (AFAIK) use the I386 Release. Maybe there is a setting in
the BIOS for I386 compat, I have no experience with AMD's 64-Bit chips
so this is just a guess. Or try disabling ACPI and everything else in
the BIOS etc... That's the price you pay for being an early adopter,
you don't need nvidia gfx for an Opteron server.
