So the bug most certainly originates upstream. The bootscript used for PowerMacs is sourced from this template: > http://git.savannah.gnu.org/cgit/grub.git/tree/grub-core/boot/powerpc/grub.chrp.in So, either the template is wrong or the part of GRUB which processes the template. If just removing the extra colon fixes the problem *and* also does not break the boot using a CD-ROM (which currently works so it should be tested it still does with the change), we should fix the bug upstream. > You have an iBook G4 so I would expect the behavior would be the same > for you as well.

I'm not sure I have booted the iBook G4 with the unpatched Yaboot so I don't know but it's not relevant now anyway. Adrian -- .''`.
