I just replaced the HD in an iBook G3 I have laying around with a toshiba 40gb. The install went fine and I formatted it in disk utility using mac os x extended (journaled). I ran it for errors and it checked out fine. I also ran the apple hardware test CD and everything checked out there too. The problem is I am getting a kernal panic no matter what I do. I started off installing 10.3 and the first disc installs fine, but then when it restarts it gets an instant kernal panic. I tried 10.4 with the same results. Then I tried the 10.2 discs that the iBook came with and it would get the very last step of the install on the 1st disc and would not go any farther. It said "one minute remaining" for over an hour. I have taken a picture of the error log that shows up and you can see here: The top line got cut off but it says "panic(cpu 0): Unable to find driver for this platform: "PowerBook4,3" Like I said, everything checks out hardware wise and i have tried three different versions of OS X. I'm at a loss of what to do so any help would be appreciated. Thanks!
