Or in any PC system? First and most important, you MUST use Luigi's driver, pcm, and avoid voxware. Using his driver, I think that any combination supported by the hardware is possible. In particular, I have a GUS PnP and a SB16 in my home machine: ... Probing for PnP devices: CSN 1 Vendor ID: GRV0001 [0x0100561e] Serial 0xffffffff mss_attach 1 at 0x348 irq 5 dma 3:7 flags 0x17 pcm1 (GusPnP sn 0xffffffff) at 0x348 irq 5 drq 3 flags 0x17 id 16 Probing for devices on the ISA bus: ... sio1: type 16550A pcm0 at 0x220 irq 7 drq 1 flags 0x15 on isa aha0 at 0x334-0x337 irq 11 drq 6 on isa ... My biggest problem was to find a good combination of DRQs and IRQs. To finally achieve a result, I had to overlap IRQ7 between SB16 and lpt0. In FreeBSD, lpt0 is registered without interrupts. In DOS/Winblows, I must not play a sound on the SB16 while printing. :) // -- // David Kelly N4HHE, dkelly@nebula.tbe.com // ======================================================================== // Whom computers would destroy, they must first drive mad.
