i think that Powermacs are by default used "APT/APM" (ApplePartitionTable/Map) and this is also that MorphOS/HDconfig called "MAC". This is recognized by MorphOS and is bootable with Powermacs.
And newer GPT is used on Intel Macs and is not bootable under Powerpc macs.
But I just think so, not search in docs.
