Here is my line: device pcm0 at isa? port ? tty irq 5 drq 1 flags 0x13 Because it is a PnP card, you either need to tell your BIOS that you do NOT have PnP OS so the BIOS will initialize the card itself, or you have to use the kernel boot parameters to initialize the card. I have these two lines in my /boot/kernel.conf (in addition to other parameters) pnp 1 0 os enable port0 0x534 port1 0x388 port2 0x220 irq0 5 drq0 1 drq1 3 pnp 1 3 os enable port0 0x330 irq0 9 For more info on PnP, see man pnp and man pnpinfo. Oh! CS4236 hangs the machine if the BIOS initializes it, this is a known bug of the chip. I hope CS4237B doesn't have this "feature". -- Mojahed To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
