So you're saying the patch is for people who don't have PCI but have PCI
support compiled in I guess?

I've only seen one PCI book at bookstores, and that's "PCI System
Architecture" from Addision-Wesley if I'm not mistaken. I was going to
buy it but I leafed through it trying to see what they have for PCI BIOS
calls. That part is 2 pages long and basically says: "The PCI BIOS Spec
is very clear on these calls, so we won't repeat it here." Not
surprisingly I didn't buy the book.
