Have you really, or did you just assume that "old" means "no LBA"?

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.
