Thank you for creating that image. Unfortunately it does not do as I
expected on my iBook G4. Despite the BootX boot script containing:
When trying to boot the ISO from USB stick using the OF command:
it still yields an error and shows that it tried:
(notice the double ":").
Manually booting grub with the OF command:
works. I had assumed that the extra ":" was coming from "&partition;"
but that does not seem to be the case.
I still believe specifying "&partition;" for an MSDOS partition table is
incorrect because specifying a partition number invokes mac-parts, which
is then unable to read the MSDOS partition table. (Using &partition; for
the _installed_ grub works correctly because in that case we have an
Apple partition table.)
I will continue to investigate why the double colon is showing up and do
some experimentation with different values to better understand how the
iBook G4 firmware is handling the MSDOS partition table.
