Hi,

The default path for the cdrom device on an Ultra 5 or 10 is
/pci at 1f,0/pci at 1,1/ide at 3/cdrom at 2,0:f
This assumes the cdrom as secondary master. If you use another position 
for the cdrom, you have to adjust the 'cdrom at x,0:f' accordingly:
0 = primary master, 1 = primary slave, 2 = secondary master, 3 = 
secondary slave.
You can change this with the 'devalias' prom command.

Regards,
Karel.
