Thanks! No rush, I'm offline for a few hours shortly, and I appreciate
all of your help so far!

I know I tried "sr2a" earlier, on the incorrect assuption of what "sr" meant.
It produced the same "Unknown device:" error. Trying just now "boot disk2 sr1"
and "boot disk2 sr2" just produce "Unknown device: srN" for each. I tried sr3
and sr4, just to cover bases. :-)
