That is fairly minor, and you already have that on the physical hardware. For pci option roms you still have the vendor and device ids that tend to be the important part. In addition it is quite possible some of those cards still follow the original option rom specification (pre pci enhancements) which simply requires the 0x55aa signature the length byte and the jump to the entry point.

Why did you remove the class code check ?

If it does not have PCI IO resource then there will be overlaping. Ollie ___ Linuxbios mailing list Linuxbios@clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios
RE: Overlaping IO resource for AMD K8
Ollie, I recall sth about mtrr setting, I wonder if I enable the NC could affect your code. Please check cpu/x86/mtrr/mtrr.c about enable NC below 4G.
