I'm right now trying to work out a way to use the BIOS information, but there's a fundamental problem related to mapping the BIOS drive number to a BSD major/minor pair. 8( > SO: The TP's seem to have LBA in the BIOS.

It's not LBA, it's probably just the EDD standard translation rules. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
