When I boot up my G4 PB, it sticks on the grey screen, at the point before the spinning grey circle appears. I figure that I might be able to fix this with a software restore, but the PB drive is also not reading any disks - it whirrs loudly and spits them out. Anyone know if it is possible to boot the G4 from an external drive, or using an iMac G5? It's a bit of a 'catch 22' situation at present. What I need to find out is a) is it possible to boot from an external drive, b) if it is, do I need to input a set of key strokes to activate the boot up (bearing in mind I can't see the on-screen instructions, and c) is there a way I can control the PB from elsewhere so I can see what I am doing (eg another monitor, or my iMac G5). I have treid rigging my PB to an external monitor, via S-Video, but again only the grey screen appears, so this seems unlikely. Thanks for your feedback, any would be most welcome. Cheers.
