Craig,

Did you just connect the CDROM to your system?

Did you check for CDROM while viewing the "devalias" command at the "Ok"
prompt of OBP
(Open Boot Prompt)? If you don't have a devalias of CDROM in NVRAM, your
system  needs
to be set up for this.

I know you can manually add this with the "nvalias" command at the
"Ok" prompt of OBP. Or,
you can "boot -r" at the "Ok" prompt of OBP to have the system recognize
the drive. If you use
the "boot -r" command, let the system reboot to recognize the
CDROM drive. After the system
is back up. Run "shutdown -y -g0 -i0" at the Unix command line to
gracefully bring the OS
down and enter the OBP "Ok prompt.

>From here enter the "boot cdrom" command at the OBP "Ok prompt.
Everything should be good
after this.
