Seems unlikely to me. My reasoning: The HD and the CD drive are on separate busses, so if the HD cable was bad, the CD drive should still boot normally, but evidently doesn't. Likewise, if neither the HD or CD would boot, an external Firewire drive still should boot. I haven't seen any mention in your previous reports of trying the verbose startup with "Cmd-v" keys at startup? The fact that you can't boot into Target Disk mode using the "T" key at startup is a very bad sign. This could imply corrupted firmware, and since Apple never released any firmware updates for the 17" PowerBook G4 you are basically out-of-luck. This idea of corrupted firmware is not common or likely because the self-test that produces the chime will check-sum the firmware, so the corruption would have to be two bits both flipping within that same portion of the firmware so that the check- sum would remain valid, and this is VERY unlikely. Are you sure it's not booting normally and the screen itself isn't the problem? Have you tried an external monitor? If you hear the HD going, and after a suitable amount of time for boot to complete you press the Power key followed by the Return key and it shuts down normally, this would imply that it's completing a normal boot process and your LCD or video card is bad. Perhaps reassemble and take it to an Apple Genius Bar to see what they think? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to Low End Mac's G-Books list, a group for those using G3 iBooks and PowerBooks (we run a separate list for G4 'Books).
