I've found an old PowerBook - the PDQ model, which has no USB or Firewire. I've upgraded it to OS 9.2 and want to get upgrade it to OSX (1.0 for now) but either the CD drive is broken, or the OSX installer CD I have is formatted in a way that OS 9 can't read, as every time I insert the disc it says it needs formatting and won't read it. I tried copying the contents of the OSX installer CD over to the PowerBook via an AFP network from my MacBook Pro, but it wouldn't copy the system files (said they were either locked or had filenames which OS 9 didn't understand). I was hoping the PowerBook drive would be formattable/installable over the network from my MacBook, but although I could see the machine on my OSX desktop, it didn't show up in Disk Utility, so I guess that option is for Firewire connection only? (which I don't have) I'm not sure any of this would work anyway as the installer.app on that CD wouldn't run under OS 9 anyway! Anyone able to help me achieve this OSX install - OS 9 seems so long ago I can't even remember what all the compatibility issues were at the time, so I'm struggling to even understand what my problem is! :/ Could I take the EIDE/ATA-2 out of the PowerBook and pop it in an enclosure and get my MacBook to reformat it/clean install OSX, and then pop it back in the MacBook? Would that work?
