I managed to get ahold of a Panther disk (thanks to one of my pals). When I inset it everything is okay, but when I hit "Restart" so the installation can begin, it give me a message saying that the computer cannot select the disc as a start up disc (or file, I forget) error (-2). Does that mean I have to use XPostFacto to make it work? I tried it on both the iMac G3 and the Beige G3. Thanks!
