I bought a used ibook g3 a1005 600mz from ebay, and I bought the following replacement parts for it -CD read write DVD read drive, -512 RAM chip, -120GB harddrive from seagate -Restore cds for iMac, with 4 software restore iMac cds with mac OS versions 10.1.3, 9.2.2, and a Worldbook media CD version 6.0.2 and and an apple hardware test cd for iMac. The reason I bought these is because I read in other blogs that you could use these cds to restore an ibook g3, even though the cds are for an iMac, because they are 'generic'. I have just replaced those parts and I have switched the computer on. It has a briefcase-looking icon (similar to the finder icon found on an iMac) that is blinking. I tried to run the software restore cds but they could not be run. First, a message soon after loading the cds 'the built-in memory has detected a problem,please contact a service technician for assistance' message comes. When you click on ok, it brings you to a box, where it says that the disk 'restore image' is the restoration disk and cannot be restored'. When I click on 'switch disk', I get a message 'the imac restore cd' is the configuration source disk and cannot be restored' Even when I install the apple hardware cd, it says that the cd does not support this system. I have a feeling that it may be because of the fact that I do not have the correct restoration cds for the ibook g3. I looked for them over the internet but could not find them. Or is it because I have a new hard-drive? Since I have a dvd drive, and I have a new hard-drive, what should I do to have the lap-top up and running? What operating system should I install? Panther, Jaguar or Tiger? Is there anyone who has replaced the hard-drive and ram on this specific ibook g3 and successfully installed the operating system after replacement? Which is the best OP for this kind of ibook? I don't mind not having the 9.2.2 version, since I don't think I shall need it. Please let me know the steps you took. Thanks in advance.
