I don't know about tape drives, but to get the /dev/cdroms/cdromx and /dev/scsi/host1/bus0/target1/lun0/cd devices, you need the scsi CD driver loaded. Then they'll exist. Presumably it's the same for the scsi tape driver as well. -- =========================================================== Paul "TBBle" Hampson, MCSE 4th year CompSci/Asian Studies student, ANU The Boss, Bubblesworth Pty Ltd (ABN: 51 095 284 361) Paul.Hampson@Anu.edu.au Of course Pacman didn't influence us as kids.
