At my school, we have a 300MHz, 512MB RAM iBook G3 clamshell with OS 9 on it currently. It does not have FireWire and trying to use XPostFacto did not work to install. Me and my friend decided that we will try to just replace the current HD with one with Tiger already on it. We already cloned the drive with Carbon Copy Cloner from a Power Mac G3 we also have running. Drive is still sitting waiting for installation. Will this work to put Tiger on this machine? Just wanted to know before my friend and I take apart the laptop to install a HD that might not even work. Thanks!
