I don't want to deter you from changing the disk and such, by if you
don't even get to an Open Firmware prompt, you won't be able to boot
from anything connected to your Mac. The OF is what will bootstrap the
bootloader stored on some media ; if it doesn't come up, you won't be
able to boot from anything. Something important must be broken ...

Good luck trying to fix your problem, though.
