    SubjectChanging PCI/IRQ config with buggy bios ?

    Hi all !

    I recently bought an Adaptec 2940, and my bios decided to allocate
    the same IRQ for this card and my video controller, a Diamond V330 (AGP!)

    The consequence is that I cannot run the xserver, it totally freezes my

    I suspect that it is a bug in the bios, but for the moment Gigabyte had
    not answered to the questions I mailed them, so I wonder if it is possible
    to do the buggy bios work in a part of a linux kernel. However, reading
    the sources, I suspect that the kernel totally assumes that the bios has
    done his job well, and can use the peripherals with their IRQ settings (or
    maybe I have read too fast).

    I do not expect you to solve that problem, you certainly have
    others things to do, but if you could give me some clues in order to do
    that, I would appreciate.

    I had an other idea, which would be to write in the bios memory
    the good values for the peripheral, and ask the bios not to reset the
    configuration data, but I don't know if it is possible. Maybe the bios
    stores only the IRQs reserved for legacy ISA cards, maybe it stores the
    information Bus/device/Irq in it, but I'm not a bios specialist, so, I
    don't know.

    Thank you for your help, sorry if you find my mail off-topic (you
    can flame me !), and continue your good job !
