The behaviour of "noupdate" shouldn't have changed. Though FreeBSD's boot2 has always ignored any partition table entry pointer that gets passed to it in the i386 SI register by the MBR code; and that means it depends completely on the active flag where multiple FreeBSD partitions are present on the same disk. > Perhaps I am abusing of your patience, but I have another question ;-) > The BIOS setup of the problem machine offers four choices for the > HD mode: AUTO, NORMAL, LBA and LARGE.

Could you help me? I've really no idea what LARGE does, specifically. I've always thought of it as just a synonym for LBA, but that evidently doesn't apply to your BIOS. -- Robert Nordier rnordier@nordier.com rnordier@FreeBSD.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
