The uk device is a catch-all for any unknown SCSI device. You can't really do anything with it (check the sources). Check the manual that came with your drive. One of the DIP switches on the back control whether the drive reports itself as a MO or hard drive. Flip it to "hard drive", and BSD will find it as sd1. Be warned; the switch may not even work.. My Fujitsu 128m always reports as MO (type 7), no matter what I set the switches at. An alternative is to update to a newer version of BSD that recognizes optical media. I'm running the 960303-SNAP, and my drive comes up as od1 (optical drive). -Dan Nelson dan@dan.emsphone.com
