For 1.1.5 you'll have to increase the number of scsi disks in /sys/i386/conf/VIDRAGONS, that is, add something like this: > device sd0 > device sd1 > device sd2 Then "config VIDRAGONS; cd /sys/compile/VIDRAGONS; make depend; make" BUT the bigger mystery to me is why that Toshiba CD rom is coming on line as a type 0 direct access device. It should come on as a type 5 read only device. As an example, here is my NEC CD-ROM: > aha0 targ 2 lun 0: type 5(readonly) removable SCSI2 > aha0 targ 2 lun 0: <NEC CD-ROM DRIVE:5012.2 > > cd0: cd present.[223153 x 2048 byte records] I'm afraid you won't be able to use that CDROM even if you add another device; the wrong device driver is talking to it and I'm not sure you'll be able to use it.
