Do you seriously intend to run FreeBSD 9 on kit that is too old to support LBA? We're talking early nineties here. CHS doesn't scale past 504 MB, so any ATA disk larger than that must peforce support LBA. I bought my first 1 GB drive (Connor CFP1080) in 1995. DES --=20 Dag-Erling Sm=C3=B8rgrav - des@des.no
