Summary: Sol 7 cdrom boot problem

No one had much to say on this. Made a call to Sun with not much found
from them either. The end results seems to be some kind of hardware

In particular I can say that prom rev is fine and the CD is fine in
this type of machine. Testing on another Sparc 20 on our campus (same
prom rev) showed that it does boot. So, we had to conclude some
hardware problem on that particular problem machine. We are attaching
an external CD (the problem drive was an internal one) and will try to
boot off that.

Thanks to my respondents.
