  The pmax kernel does some trickery for the disk configuration to get the
current autoconfig to work with the old pmax SCSI drivers.  This is mostly
in src/sys/arch/pmax/pmax/conf-glue.c.  The current configuration only
recognizes disks rz0-rz4, and leavs targets 5 and 6 for tape devices.

  You will either need to change the disk to use target 4, or rebuild the
kernel and add an entry in conf-glue.c for a disk at target 5 (and the
corresponding entry for rz5 in your kernel config file).
