A few months ago I bought the 2.3 CD's from Terra soft. Since I'm now on break for the summer I have some time to play with Linux, unfortunately I cannot get a burned 3.0 disk or the factory 2.3 disc to boot my computer when restarting with it in the dirve and holding down the c key. The 2.3 Disc worked on an iBook in January. Thanks Ben Snitkoff
