If nothing stands out directly, try assigning at least on IRQ (maybe the expected one for the chipset) to 'Legacy ISA' and see if that helps. if bios fiddlement doesnt help then u probably have to write a driver for that bridge chip. > And I also tried shuffling around IRQs to a couple of different > unused values....maybe I should try a used value and see if it breaks > something.... > > > have you heard the sound work in windows? > > > it had windows when I first got it, and now I cant remember if it palyed > sounds or not.
