The RAID code is implemented in the ATA driver (ata-raid.c) and tbat takes over from the BIOS as soon as we are airborne (the BIOS is only needed and used for booting). However, there is no way to rebuild the ATA RAID from FreeBSD (that may soon change though) you have to use the BIOS for that... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
