I burned the iso file to a CD, unzipped the iso & burned to a CD too... Using Nero Express and telling it to setup the CD as a boot disk. When I use either, it will only go to Dr-Dos after the checking. I am running the latest Knoppix on HP Pavillion ze4600, ,256 MB RAM, and 40 GB hdd. What am I doing wrong & any more info to how to get to Knoppix on it? PLEASE HELP.
