As for the required size we should probably consult wit Grub maintainers. I guess it depends on which modules is grub binary going to need. The rule of thumb for Yaboot was 800KB HFS partition, but grub might need more and you want it to be future proof. > > Question: Does GRUB work on all the PowerPC variants that Yaboot supports? > > According to [1], Yaboot supports: > > - Mac Newworld, CHRP, CHRP/RS6000, CHRP_IBM and Cell. > > Are these all supported by GRUB?

There is a Quik fork named iQuik which is amazingly enough still maintained. Take a look at this: https://github.com/andreiw/iQUIK/blob/master/README Although, I'm not quite sure if the effort to support oldworld Mac machines is worth doing. M
