It's possible the CD isn't entirely correct, as IIRC SGI cd's need to have
a special SGI-specific format to be bootable; unfortunately, my Indigo2 is
still packed away and last I tried couldn't boot of either the internal CD
or an external CD on controller 1 (the internal one has a dodgy sled and
either doesn't get power correctly or doesn't make the SCSI connection 
right; the external one seems to have died a spontaneous death and won't
even talk to my PC anymore 8-/).

I'll see if I can scrounge up a SCSI CD-ROM to try this out, but I wouldn't
count on that being real soon... For the time being I suggest you boot off
the 'net if possible.
