    When i boot up my ibook G4, i hold the Command-Shift-Option-Delete, which should select in the Startup Disk control panel in favor of an external device or from CD-ROM. But, the thing is that when i do this it brings up a blue folder and inside is a flashing "?" and the smiley 2 face icon thing.

    What does this mean?

    Why are you holding command+shift+option+delete? The boot menu is accessed just by holding option.

    The invocation of DOCS will search for alternative bootable volumes on your iBook. If nothing appears then it cannot find one. You must also have your external device connected on the Firewire bus as USB booting was not supported fully until the Intel Macs showed up (some G5 models could be USB booting as well).

    Not on Power PC Macs.

    That'll come as a surprise to my iBook G3 and Power Mac G5.

    So your saying if nothing appears and it cannot find one, is there a way for it to find one through the USB on a external device?

    Yes, that's what I'm saying.

    No, as I said, you cannot boot a G4 from a USB device. It must be on the Firewire bus to boot externally.

    No. PowerPC Macs cannot boot to USB drives.

    You can for some, but it takes a bit of trickery.
