I've got a pcchips M572 motherboard with an AMI bios and I'd like to get it running with a K6-2+ 450Mhz cpu.
The board has an Intel TX chipset and supports 2.0V Vcore.
I've flashed it with the latest pcchips bios I could find (990224s.rom), but when I try to boot with the K6-2+, it just hangs at checking NVRAM. It identifies the CPU as an "AMD3366", which I don't think is quite right. I've disabled all cacheing of the bios, to no avail.
Incidentally, it boots fine with an Intel Pentium 233 MMX.
I suspect that I need to patch the bios to recognize the K6-2+.
I understand that this is going to require some assembly language programming, although it's been awhile since I did that.
What are people's views on the best tool to use to extract the AMI bios?
Also, can anybody point me to some information on how I can locate the CPU table, as well as whether there is anything else I need to do to patch the bios to get the K6-2+ to work?
