Nope. I wanted it to boot from cdrom *ONCE*. That machine kept on booting
from disk and I wasn't able to find the program 'selecting boot device'
which I have seen on the cdrom once. I needed to boot from cdrom in
order to remove the existing MacOS and install it on a shorter partition
to free 2.1gb for our Linux development.
An introduction of the commandset of OpenFirmware would be nice but
I haven't found one.

Neat idea, but how does I do this? I'm not a OF freak - and even that
I know something about it now, I wasn't able to find the cdrom, I found
the two scsi disks and the ide disk but no cdrom. One hour later and
I would have taken a scsi cdrom from another machine...

It's an internal ide cdrom, standard pc hardware.
Nope, it's a StarMax 4000 (Motorola clone)

On this system scsi-int == scsi as well as ata == ata-int (couldn't test this)
