Forgive me :) last time I read something about disklabel on macppc was 
months ago.
Additionally, without any particular reason I assumed he asked that with 
a dual-boot pourpose.
Thank you for the explanation, but now I've another question.
You mentioned the device driver section of a partition map, and so does 
the Partitioning Howto:

    ...
    1: Apple_partition_map Apple           63 @ 1
    2: Apple_Driver43*Macintosh            56 @ 64
    3: Apple_Driver43*Macintosh            56 @ 120
    4: Apple_Driver_ATA*Macintosh          56 @ 176
    5: Apple_Driver_ATA*Macintosh          56 @ 232
    6: Apple_FWDriver Macintosh            512 @ 288
    7: Apple_Driver_IOKit Macintosh        512 @ 800
    ...

Now, I cannot remember if my original APM had such kind of "partitions" 
but my actual one does not have any of them for sure.
Are they useful only on old systems? (mine has OF v3)
What are they supposed to be/do?
Thank you.
