supported under Mac68K shouldn't be able to get going with
MacPPC. The 540c I've got is not supported in its native
form because of the 68LC040 processor, not because of
OpenFirmware.

but I haven't had any success here. (I downloaded and burned
a CD for macppc-3.1 but I could not get it to boot.)

This begs the question then why we can't just scavenge the
Mac OS bootloader and do whatever it does? I should think
If Mac OS can boot from CD, we should all be able to boot
from CD.
