The CD-ROM that comes with this computer contains an old version of Red Hat Linux, version 6.0, as opposed to the latest version 6.2. It didn't have the drivers for my newer computer, so I purchased the 6.2 box, and this really is significantly better. Since the book just covers 6.0, I've found the Red Hat documentation to be more useful than it. Even if this book were up to date, it is still poorly organized and incomplete. I just purchased the book Special Edition Using Red Hat Linux, and while it is lengthy, it covers 6.2 (with CD-ROM) and seems quite straightforward.
