Hi, I have an iBook G3 (Panther) giving me probs and I want to connect it to my Intel iMac (10.4.10) using TDM and Disc Utility to zero out the Physical Volume of the iBook so I can reinstall Panther using TDM, but from a PPC iMac. My concern is that the necessary Firmware Update 4.1.7 that I applied prior to upgrading the iBook from 9.2.2 to Panther, will be wiped along with the Physical Volume??? Or maybe it won't? Can I even use Disc Utility on an Intel Mac to zero the iBooks HD? Or do I need a PPC iMac? I don't want to reinstall Panther on the iBook if the Firmware Update has been removed as I know this is not a good move.
