I wonder if it's a problem with my motherboard then, because I've never managed to get the machine working with both slots populated, on combinations of: A NatSemi DP83815 10/100 NIC Adaptec 19160B Ultra 160 Controller AverMedia Brooktree 878 Based WinTV FM 98 card Creative Labs EMU10k1 Based SB Live Value CMD 649 Based generic 2 port ATA card Promise TX2 ATA100 Controller Sil 0680 ATA133 Controller ADMtek AN985 10/100 NIC Certainly some of these cards should adhere to the spec? Even two Promise TX2 cards (which share a bios and everything) cause FreeBSD to panic on boot if they're installed in the bottom slots. -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
