Interestingly enough, I've never had a problem with the wrong BIOS info from my DPT card. Only with the incorrect sensed info when using the DPT driver on a RAID-5 array when that array is in degraded mode. The fact that it panics trying to boot is amazing to me. It is NOT trying to boot from the RAID-5 by the way. > As for your problems, I'm sorry to hear about them, but have no idea > how to fix it. I've had none of the problems you have :-( Lucky for you, less so for me. ;) -Troy Cobb Circle Net, Inc. http://www.circle.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
