Somewhere about the P100 (that's Pentium 100) machines you can't find less than PCI 2.1. Next time tell more so people can see if your motherboard has it or not.
How can I tell what version of PCI I have?
Is it possible to upgrade if my version is not 2.1 and I need it to be 2.1? How would I do that, upgarding the BIOS? Changing the processor?
Any help would be greatly appreciated.
