>Description:
The Toshiba XM-3401TA SCSI CD-ROM does not identify itself
as a "CD-ROM removable" SCSI device. It claims to be a
"fixed direct" SCSI device. As a result it gets attached
as an sd? instead of a cd?.
>How-To-Repeat:
Connect a Toshiba XM-3401TA SCSI CD-ROM to a system,
reboot, note result of device probe.
>Fix:
Apply the following patch (derived from the stock NetBSD
1.3.2 dev/scsipi/scsiconf.c):
