Well, I wasn't laughing, and apologies if it came across that way.
However, I was slightly annoyed at your apparent success in getting 
where the documentation says you should get, and then all the 
experimentation with boot flags when you already reached the goal.

Correct. The boot flags are not applicable. When you get to the '$' 
prompt, you have succeeded. No point in futzing more. We could try to 
figure out what the effects of the boot flags are, and other possible 
things you could do from the CD, but that would be unrelated to 
installing VMS.

That is a different problem, and needs to be figured out with the DSSI 
disks. I assume you have not pushed in the write protect switches. You 
could connect to the disk drives, and check the status from that side. 
There are diagnostics you can run, and so on, on the disks.
The VAX boot environment on your machine have, I believe, the ability to 
connect you to the disk drives. I can't remember the details, so you'll 
have to either search manuals, or ask online about that.

My only actual recollection of when something like this can happen is 
when the drive decides that some data are unreliable on the disk, and it 
write protects itself, in order to give you time to recover. But since 
you want to do a clean install at this point, you would want to ignore 
this feature. I would hope the built in diagnostics could help you 
there, if this actually is the case.

Good. You know how to get to the '$' prompt. Thus, booting from the CD 
is accomplished, for the task of installing VMS.
You now have a problem with the DSSI disks to solve, in order to install 
New problem, new questions. :-)
