Wow, you're kidding! All I need is cat? I thought there was some long drawn-out process involving dd. Also, cat will copy all the subdirectories on the CD recursively?

This sounds simple. I have one problem, however. The machine with the burner does not have an HDD install of KNOPPIX yet. Can I boot the CD in question and use cat to create an ISO on the DOS HDD? Can't I just remount it for read/write access?
