    I can't make head nor tail of the table on page 2-18 of the board user guide.
    Can someone tell me what shares interrupts with each PCI slot?

    Thanks

    Here's the Everest resource report on mine.
    The only PCI slot I have populated is the one closest to the CPU.
    It's got IRQ 21. Maybe you can extrapolate with that.

    You have to remember that there was a P5P800, before there was
    a P5P800 SE. The original board had a 5th PCI slot, which is
    apparently missing from the P5P800 SE. On the original board,
    PCI Slot 1 and PCI Slot 5 shared the same interrupt line.

    Now that slot 5 is gone, PCI Slot 1 is no longer shared. So the
    entry in the P5P800 SE manual is not quite correct, as it should
    read "Used" rather than "Shared" for slot 1.

    PCI 2 shares with Onboard LAN.

    PCI 3 shares with Onboard USB2.

    PCI 4 does not share.

    So it looks like PCI Slot 1 and Slot 4 are the good ones.

    And in the best of times, the table in the manual is not
    always correct. Sometimes the true wiring is revealed, when
    someone with a machine full of PCI cards, dumps their interrupt
    table in a USENET posting. So it is quite normal to find
    contradictory information via your own testing. "Vic"'s posting
    suggests Onboard Audio is actually connected to "B", and
    it looks like his Promise Ultra133 was in slot 1, based on the
    order of assignment in Windows.

    Thanks Vic - Pauls's post explained why the manual was confusing
