>Environment:
System: NetBSD awaken 1.3.2 NetBSD 1.3.2 (AWAKEN) #4: Tue Apr 20 12:27:27 EDT 1999 fredette@awaken:/u2/src/sys/arch/sun3/compile/AWAKEN sun3


>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):
