Folks, sorry for a newbie question. I own a G4/450 AGP and an iBook/800. I want to use the iBook as a backup for my G4. I know how to set it up as a slave (cmd-t to start it up from a Firewire connection) and then use a soft (Personal Backup) to synchronize. However I cannot simply clone the G4 since the two systems must differ somehow (not the same ROMs and anyway Apple prohibits this). So what *exactly* should I exclude from the backup once the iBook is in slave mode? All of my Library folder?; less?; more? Also can I after that install Tiger to the iBook by an Archive & Install option? Thank you. My setup: 1. G4/450 AGP Panther9 896MB RAM 2. iBook/800 Panther9 512MB RAM Cheers -- Michel Eytan eytan at umb.u-strasbg.fr I say what I mean and mean what I say
