I have an iBook clamshell (blue) with a 6 gig hard drive and 320mb of memory. The firmware is upgraded if 4.1.7f. I recently inherited this and wiped the drive clean and installed OS 9.2.2 from an iBook disc. No problem. However, I seem to be unable to upgrade to OS X. I have a retail Jaguar disc (10.2.2.) and every time I put it in the drive, it boots to the Apple logo and then freezes right there. I thought it might be the disc and so borrowed one from a friend and the same thing happened. FYI, both discs appear to be fine with no scratches or marks on them. So what's my next step here? I have no external hardware connected, no firewire port and no access to another Mac (although I do have a PC if that helps). Any suggestions appreciated. Thanks.
