Try (from the OF prompt)

	setenv boot-command boot scsi-int/sd@0:0,ofwboot.xcf
	reset-all

After that, it should boot automatically as long as power is
not lost.  (reboot)

This may not work though, on a cold boot 'cuz the disk hasn't
fully spun up.  You might have to power up, and then wait about
15 seconds, and then hit the NMI.

Ther are some patches out there that you can add to OF to add the
delay to the boot.  THat takes a bit more futzing.
