My Compaq V2000Z laptop booted the Knoppix 4.02 Live CD with no cheat code options; however, Knoppix 5.02 requiires the cheat code NODMA or it won't boot the live CD. My Knoppix live 5.02 live flash thumb drive will boot without the NODMA cheat code; however, it hangs the OS if I try to access the K3b CD/DVD burning application. Anyone have any idea what changed between 4.02 and 5.02 reqarding this issue??

Thanks Very Much In Advance
