I just installed NetBSD 1.3 on my sparc2 clone (a Trigem SDT-400),
and now it can't seem to find the tape drive (an Archive Viper 150).  
It worked fine with the version 1.2 that I upgraded from.
Unfortunately, I now want to get some stuff off the backup tape that
I made prior to upgrading.

There are no hardware changes during the upgrade.  I have three hard
disk drives, and the tape is SCSI ID 4.  Probing the SCSI bus from the 
PROM monitor appears to find the tape drive successfully.

However, during boot, the kernel generates some error messages (see
below), and subsequently, attempts to use /dev/rst0 produce "device
not configured" error messages.

These are the kernel messages at boot time that relate to the SCSI 
interface:

Thanks for any help.
