My wife has a 2001 ibook (its either dual USB or late 2001 model at 500mhz) that is running 9.2.2. I am looking to start over completely with OS X and have discs for 10.3. However, when I begin to boot, I receive this error: panic(cpu0): Unable to find driver for this platform: Powerbook4, 1 This happens before I have any sort of action or anything even visible aside from the giant apple on the screen. 9.2.2 works like a charm, and I can install 10.0 (not really wanting to go that route) without any problem, but 10.3 would be perfect. When I attempt (I've made many attempts), I unplug every external device prior to boot up so it is just me, the ibook, and the power cord. But, usually, it has a USB mouse, USB keyboard, external monitor, and firewire CDRW. I have even removed the extra memory and swapped it for new memory. If anyone has any insight, I'd be most appreciative. I ran across the same message in the archives, but it was a different situation. p.s. I did attempt to see if I needed a firmware upgrade, but I did not.
