As it says in LINT, the sound ports and IRQs are hard-coded in i386/isa/sound/sound_config.h . Also from LINT, it expects sb0 at 0x220, IRQ 7, drq 1. The other half of the problem is PnP behavior on the ISA buss -- you need to disable the PnP behavior and force fixed addresses for the various sb functions. Otherwise it will screw with all IRQs that it *might* be using. -- Ken Are you interested in | byte-sized education | http://www.play-hookey.com over the Internet? |
