I have been watching this project from the early days and I'm impressed
with the recient progress.
This is probably old news but a quick search of the archives here did not
show anything up.
Yaboot is the bootloader used by owners of macintosh and other ppc
machines with open firmware to boot linux from openfirmware. The home page
seems to be http://penguinppc.org/projects/yaboot/
Perhaps when the time comes to boot an operating system with openbios
yaboot and linux will be good candidates.
Of course I may be completely off track!
Bye for now
