In message <20010207031637.A32676@elvis.mu.org>you write: }It its the bios disk probe that is causing the machine to fault. I can now confirm that it's a divide by zero in the Adaptec BIOS GRRRRRR. (in biosdisk, when 'probing' the adaptec) and it happens on a AIC 7899, but works ok on some other ADAPTECs. the problem is nasty because it's not easy to zero out the first block of the disk if you can't get the os working :-) }I suppose you really dont need to probe the disks when you are netbooting. i got the pxeboot not to check the disks but then the kernel stepped on it :-( is there a way to prevent BTX to halt if the 'caller' expects a div/zero? (in the days of the PDP/11 i could trap such things, print a message, and continue). danny To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
