For example, I have an older MB that has 3 PCI slots. Each slot is assined an INT (A, B, and C) and each INT can be assinged a system IRQ. I was having trouble getting PCI cards to work, most recently a NIC, and found that they only work in PCI slot 1 which is assigned INT-A. That would not be so bad except 1. I could only use 1 PCI card, 2. INT-A can only be assigned IRQ14 (which conflicts the onboard IDE) or IRQ5 (which just conflicts everything), 3. PCI slot 1 is a shared PCI/ISA slot, so I lose an ISA slot too! :( Anyway, if I put a card in PCI slot 3 for example and set IRQ15 to it, when 2.2.6-R starts it finds the card and the IRQ assigned to it by the BIOS, but it reports that the card is using INT-A when actually PCI slot 3 is INT-C. Alas the card won't work. Put it in PCI slot 1 and all is fine. Any ideas or information?
