And yes, it has NT on it (hence NTFS). I don't know what to make out of it, but I hope you can.

The RAID code is implemented in the ATA driver (ata-raid.c) and tbat=20 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... -S=F8ren _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
