I have a normal pc desktop machine with a msi k8t neo-v motherboard which utilizes an AMI BIOS. I have a pci video card in an expansion slot. On bootup POST, the BIOS complains about a routing table error on device 0:05:00 which pionts to my video card (the only PCI device in an expansion slot). This motherboard does not have onboard video so I need this video card in order to see anything (as I do not have any backups). This video card works flawlessly in another machine (different mobo/chipset/bios). I have done some searching and it seems I need to look for a "pnp os" setting in my BIOS; none exists (or the the mobo manufacturer has conveniently removed the ability to alter this setting as a lot of them do to a stock BIOS).
So I've come to the point where I want to disassembly/debug my BIOS to see what the exact error is. I can use dos debug to find the location of the '$PIR' signature of the routing table and maybe will only have to analyze the data and this will show what the inconsistency/error is. Otherwise I need to do some really-involved disassembly/debugging.
The video card still works, however very slowly. It's like it's "painting" row by row....very obvious to the human eye. CPU utilization runs up to 90% for a simple act like scrolling a ms-windows notepad window (and takes a couple of seconds). The card itself is a 5volt PCI ATI Rage Mobility card (mobo supports 3.3 & 5 and AGP up to 3.0).
I've reset CMOS, removed/reinstalled battery, disconnect power chord from psu, disconnect all connections to the mobo including the atx PSU connector, reseated the video card in all slots, removed/reinstalled the cpu (which isan AMD Athlon 64 @ 2.0Ghz, 200MHz HTT x4 = 800MHz FSB), tried different memory (current is 512MB ddr400 [200Mhz bus], and even booted up with only memory, cpu, psu, and video card hooked up and still same error.
Any tips/pointers?
