Any/all suggestions will be gratefully received. First step would be to boot with a serial console and -v, so that you can narrow down the point at which it's dying. After that you'll probably need to apply some printf-style debugging. At a guess, I'd be worried about some of the BIOS probing and calls that go on at around that stage, as well as the memory probes. More data would give us a better idea, of course. If anyone in the SF Bay area has one of these boards they could lend for a few days, I could probably help narrow this down fairly quickly. -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
