I have been trying to set up a shared Airport network between an iMac G3 and a TiBook G4. The TiBook is accessing the internet no problems using Panther and Airport. The iMac will not install Panther as it says it requires a firmware upgrade, which I cannot find. The iMac cannot access the shared Airport connection unless both systems are running the same OS. I have come to the conclusion, what with various issues with 10.3, that I would be best advised to re-install 10.2.8 on the TiBook to match the iMac. Then I hope both would access Airport. Again, re-installing Jaguar is proving a nightmare. The install disk crashes the machine as soon as it is loaded. Can anyone offer any advice. Cheers Very frustrated Stan.
