The drive (a Maxtor) handles LBA and looks like it has fewer than 1024 cyl instead of the 2448 it actually has...instead of 2448 cyl and 16 heads, it is remapped to appear to have 612 cyl and 64 heads. Since FreeBSD uses the geometry from the disk (2448x16x63) instead of from the BIOS table (612x64x63), it gets confused. However, I still don't understand why the install floppies won't boot (I can boot DOS or Win95 or OS/2 floppies), nor do I understand why I can't boot FreeBSD from a second, non-remapped drive (it was installed there before I got the 1.2G drive/EIDE controller and worked just fine). The controller is a DTC 2278E, which replaced a DTC 2278VL. Very frustrating and disappointing. As these drives become more common I'm sure there will be pressure to make FreeBSD handle them. I believe Linux already does. If I had time, I'd try the hack myself...if I had a system to do it on. Oh well...I probably shoulda spent the money on a SCSI drive and controller. Mark
