Thanks to Alan Rollow, Dan Byrd, Selden Ball, Dr. Blinn, Johan Brusche,
and Steve _at_inel.gov.
Most of you wrote off my poor little CD ROM drive and figured it was dead
:-) .
Alan Rollow seemed to have a little more faith in it, and suggested I look
at the I/O path. So I grumblingly pulled the DS20 off the shelf, removed
all the panels, blew off all the dust, checked, and tightened all the SCSI
cable connections. Put the box back together and powered it back up. The
machine finally booted off the CD with no further problem.
Thanks everybody, for your suggestions.
--Alan Rollow's response--
If other systems can indeed read the same disks, you need to start looking
at the device and the I/O path. In the first case, it apparently couldn't
even read the boot blocks. The 2nd got that far, but couldn't read the
file system. It could be the drive. It could be the I/O adapter
(probably a built-in IDE channel for the DS20).
---Original problem---
I am attempting to boot the operating system CD on our AlphaServer DS20
with firmware v6.5, and it doesn't seem to work. I have verified that
other machines can boot the CD but this particular machine cannot do so. I
would prefer the 5.1a disk to work over the other two versions, but that
gets even less far than older CDs.
When I use the Tru64 5.1a disk I get the following output
P00>>>boot dka500
(boot dka500.5.8.1 -flags A)
retries to pka0.5.0.8.1 exhausted(cmd-0 sts-2)
failed to open dka500.5.0.8.1
P00>>>
When I try to use the Tru64 5.0 and the Tru64 4.0f disk, I get the
following output:
P00>>>boot dka500
(boot dka500.5.8.1 -flags A)
