Sun OBP not keeping cdrom

[kurt at verruckt.org]

This may come as a stupid question for some, but i am trying to change my
cdrom back to default. For some reason, it will not hold the change. Here is
what shows:

devalias cdrom /pci at 1f,0/pci at 1,1/ide at 3/cdrom at 2,0

>From what i have been told, it SHOULD be:

/pci at 1f,0/pci at 1,1/ide at 3/sd at 2,0

Any sun gurus know how to make this change permanent? Everytime i reboot the
change goes away.
