Booting straight in disk with install ofwboot.elf iso.

Hi,

I found a tutorial which teach how to install NetBSD macppc in a Mac mini G4 1.42 GHz booting straight with ofwboot.elf iso insert in disk. However, when I try to use disklabel after to execute dd command, disklabel doesn’t record my edition in disk (it says which there is an inconsistency between disk and label or something like that).
I have some doubts! Is it necessary which disk had a scheme (possibly APM) or can disk be raw?
If first case is correct, is it necessary that scheme disk must be set with MacOS's Disk Utility or can I use pdisk's "i" command to set MacOS partition (bootstrap?)?
