i saw this post that was here recently about this but it didnt help. i get this message everytime i try to boot knoppix on my desktop which has a 256MB nvidia card, intel board, 1 GB corsair ram, 3.4 GHz intel dual core (800MHz fsb), and a new sony dvd drive (i have tried it on a few different drives though). the same burn works fine on my laptop (sony viao). i tried all the cheatcodes that were suggested and a few more. im not brand new to knoppix or linux, but i dont kno a lot about it. any ideas on what might be the problem?
