you want to learn OpenFirmware, and Forth, which is what OpenFirmware
is implemented in.  you will find more useful info on OpenFirmware
from Sun Microsystems then you ever will from apple.  also look for
RFC (or whatever it is) 1275 thats the OpenFirmware spec.

nothing can be done under macos.  mac-fdisk can do it, but the only
way is by deleting and recreating the partition, if you do this
carefully and verify what you did before wrting the table this is
usually safe.  i would only do it with the mac-fdisk in woody though,
not potatos and certainly not LinuxPPC's.  just use `d' to delete it,
then `b' to recreate in the same starting block. 

if you are really brave use a hexeditor on /dev/hda1 ;-) just change
the Apple_HFS to Apple_Bootstrap.

mandrake may very well have parted on thier CD, i think that may be
what they use as a backend to thier partitioner.
