Option should do nothing in a B&W G3 on boot -- that feature (like the
FireWire target mode activated by holding down t on boot) was introduced
with the first G4s IIRC.

Similarly, holding down c will only work if you have a bootable CD (whatever
OS) in the CD-ROM.

(just guessing here) "boot hd:7,yaboot" may work for you. If that works,
"setenv boot-device hd:7,ofboot.b" would be what you're looking for (don't
ask me what that does, I just know it worked for me ;)

BTW One further comment to your earlier posted solution of pulling the PRAM
battery and using the YDL CD to install (& force your bootloader partition
to become startup). I managed to get yaboot back simply by doing a "faked"
install with the CD without having to do a PRAM reset or pulling the battery
(this was before I found out about the Open Firmware commands).
