That generation of machine had a SCSI cdrom, so just do

probe-scsi-all

to see if it shows up.  Make a note of where it is if it does show up, 
and check the definition of cdrom in the eeprom settings.  If I remember 
correctly, the eeprom command is 'showenv'.

You can also boot to the exact device using the whole device path.
