Perhaps this is what's happening to the > happless user who started this thread. I think this may be the case with the PCI sound cards. Every single one of them I tried wasn't identified by the manufacturer in SRM, like every other card in the machine was. The PCI sound cards are just identified by two sets of numbers, which I guess correspond to vendor ID and part number. > Drew > Thanks, Josh To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
