To the OP.
From the OK OBP prompt, can you please share the output of:
probe-scsi
AND
probe-scsi-all
assuming your OBP supports those commands.

Oh! And if you're using the "boot cdrom" mnemonic, make sure that your
CD-ROM is actually set to SCSI ID 6, otherwise you need to substitute in
your boot path i.e.
/iommu/sbus/espdma@4,8400000/esp@4,8800000/sd@{scsiid},0
Definitely check that!

Subject: SPARCClassic won't boot cdrom
Hi all!
I recently acquired a SPARCclassic, which is my first bit of Sun
hardware. Having an awful time getting it to boot from the CD-ROM. I
have
tried a bunch of different terminators and several different cables, but
whenever I try to boot I get this:
ok boot cdrom -s
Boot device: /iommu/sbus/espdma@4,8400000/esp@4,8800000/sd@6,0:d File
and args: -s
The SCSI bus is hung. Perhaps an external device is turned off.
Any ideas as to what might be wrong here? The thing does not seem to
send any commands to the CD-ROM, as the LED never comes on and I don't
hear
it doing anything...
Thanks!
-Ben
The terminator on the end of the SCSI bus needs to be powered. Without
power on the terminator the bus will hang. Sometimes the power comes from
the SPARC through the SCSI cable, but not all SCSI cables pass the power.
Sometimes there is a jumper or switch on the last drive to enable SCSI
terminator power.
