I've got a 53c810 in my PC164 with a couple of CD-ROM drives hanging off
it. For some reason, they often give me:

>>>show dev
dka0.0.0.7.0               DKA0                CD-R/RW RW7040S  1.10
dka600.6.0.7.0             DKA600       PIONEER CD-ROM DR-124X  1.01
dqa0.0.0.11.0              DQA0        QUANTUM FIREBALL EX3.2A  A0A.0D00
dva0.0.0.0.1               DVA0                               
pka0.7.0.7.0               PKA0                  SCSI Bus ID 7
>>>boot dka0
(boot dka0.0.0.7.0 -flags 0)
dka0.0.0.7.0 has no media present or is disabled via the RUN/STOP switch
failed to open dka0.0.0.7.0
>>>

This is with media present, and both drives have done this, though
on other ocassions I get different errors. The disk I burned has
an ISO image that apparently boots on other Alpha systems. Thoughts?
