The hda2 partition is only needed with nonApple Operating systems. You can boot the macosx installation CD without it (I'm always talking about newworld machines). The bootstrap partition (hda2) is where linux kernel (and I suppose the BSD one) is installed so OF can boot it, for MacOSX, OF can boot directly from the HFS+ partition. > > bye just now, > > Cheers. > -- > Matthew T.
