Just using md5sum on /dev/cdrom WILL NOT WORK. The actual burned CD image is different from the iso file, but I don't know why. Even using md5sum on the SAME CD between 2 different drives will give you different answers. I know these things because I just tried this yesterday because I wanted to do the same thing Marco wants to do. I *know* I saw the proper way to do this online somewhere, but I can't find that information now. It was something about doing a dd out to a loopback and using md5sum on that??? Unless someone can post the definitive way to do this, the best thing you can do, unfortunately, is indeed, like others have said, boot the image and perform the tests. Regards, dk
