It seems all my macs are having problems lately. I have a ibook G4 which I can't seem to boot up without getting the folder with the mac face, no matter what keys I press on start up. I had read somewhere (probably a mistake to try this) that if you connect the iBook to a desktop iMac via firewire, you can install the OS DVD. So I put the iBook G4 disc into the desktop (perhaps I should have put in the Tiger OS X designed for desktops?) but I did not install. I ejected the disc when the computer didn't respond to it like it would the Tiger OS X DVD, before installing anything. I disconnected the firewire cable, and rebooted the iMac, only to find that it too had the screen with the folder and the mac face. I tried booting it with Command + Option + O + F since I couldn't boot it up with the OS DVD, but it's asking for a password which was never set. Is there any way around this? Or is this the wrong approach all together?
