installation problem on Sun E450

[m]

I just picked up a Sun E450, and I'm having installation problems.

After I get the system banner and the "OK" prompt, I type "boot cdrom", and
get the following:

Initializing Memory
Boot device: /pci at 1f,4000/scsi at 2/disk at 6,0:f  File and args:


The cdr DOES spin up, then the system totally freezes.

I had thought I needed perhaps to have a serial console attached, in
addition to the keyboard/monitor, but that does not seem to make a
difference; nothing comes across on the serial terminal either.

Any help would be MOST appreciated.  If anyone needs more info regarding
this, just ask & I will provide!
