No, it means partition in the on-disk disklabel, whatever form it might
take. :-)

Look at usr/src/sys/arch/macppc/stand/installboot to see how the ofwboot
booter gets shoved onto the disk. Note that this method got broken with
revision 3 firmware (the imac & later). They only boot from a file on a
filesystem.

Take care,
