Well.. Who knows. I am still confused because I don't understand have any datasheets in front of me.

Maybe I am getting old, but I haven't found any PnP BIOS's I really liked. They all make too many assuptions on my behalf. In userconfig there is a pnp entry on irq 5, that looks like it is the soundcard, however I can only change the irq to 0 (disable). Don't seem to be able to change to any other irq. Does this have anything to do with pnp overides? Could you please say a few words about when one can override the IRQ the BIOS assigns to a PNP device with the kernel and when not. Thanks.
