If I try to enable the lpt port the sound card no longer works. Part of the problem is that the sound card is on IRQ 7, and I can't find a way to change it back to 5 (the default) There are no jumpers on the card to change it. So, what I have done to try to resolve a possible confilct is to change my lpt port through the BIOS to IRQ 5. FreeBSD 4.3-Stable Kernel Config: # Parallel port device ppc0 at isa? port? irq 5 drq 3 device ppbus # Parallel port bus (required) device lpt # Printer # Sound card device pcm device sbc0 at isa? port 0x220 irq 7 drq 1 flags 0x15 The sound card is not PnP. I have tried removing everything after the sbc part (Including the 0). dmesg output for the sound card: bc0: at port 0x220-0x22f irq 7 drq 1 on isa0 sbc0: alloc_resource device_probe_and_attach: sbc0 attach returned 6 I would like to do one of two things: 1. change the IRQ used by the soundcard back to the default, so the lpt port can do the same. (I know that a utility for this once existed, but I have been unable to find it on Creative's site) or ... 2. Find out what else needs to change for the lpt port so that It can use IRQ 5 and not cause a confilct with the sound card. Thanks for any help! -- | David L.
