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.

Push twice the Tab key and see the list of kernels to boot. If you have the default, you should have a 'Linux' entry so you should type: boot: Linux init=/bin/sh Cheers. > > Regards > Giovanni > > __ > Tiscali ADSL Senza Canone, paga solo quello che consumi! > Non perdere la promozione valida fino al 31 agosto.
