Okay, I've reinstalled and after installation was successful, I entered 
the following commands in the shell:

mount /dev/sd0a /mnt
cp /usr/mdec/ofwboot /mnt/boot
/usr/mdec/installboot /mnt/boot /usr/mdec/bootxx /dev/rsd0a

No errors.

So then I rebooted into Open Firmware. The 7600 says it has Open Firmware 
1.0.5. What magical incantations do I need to enter to boot now from the 
SCSI drive?

Entering 'boot scsi-int/sd@0,0' got the reply 'Can't load from device' if 
memory serves.

Yes, I do work for Apple (in Canada) but don't have a lot of contact with 
Engineering. If there is something specific you'd like in terms of Open 
Firmware docs, let me know and I'll see if I can turn over a few 
stones... ;)
