it's recognised and assigned to the 'unknown' driver it is therefore accessible through the uk0 device unfortunatly uk devices only know how to do generic scsi operations (see man 4 scsi, man 4 uk) (also man 8 scsi) is this divice treatable as a hard disk? oris it write -once only? if it can be made to read and write, then you can FORCE it to be assigned to the sd (scsi disk) driver by adding a line to the file /sys/scsi/scsiconf.c (in two places, as there are two different configure options #ifdef'd there) that specifies the exact configuration options to look for, and then specifies that such a device should be assigned using sdattach there are quite a few examples there.. you then compile a new kernel (there's an FAQ on that in /usr/share/FAQ) and see if it works.. > > Hi, > > I have FreeBSD on a Gateway machine, and am trying to get a SCSI > optical drive to work.
