Knoppix STD is not Knoppix, it is a small set of tools on a Livd CD based on a very old version of Knoppix. You would do yourself a big favor if you would follow the Get Knoppix link near the top of this page, use BitTorrent, and download a nice new copy of the Knoppix 4.0.2 EN CD or DVD. I would also suggest reading the downloading faq in the wiki found by following the documentation link near the top of this page. It sounds like you have already downloaded and burnt an ISO, but there may still be information in that documant that is new to you. That might in itself be enough to resolve your problem. You have a pretty popular card and I don't remember others complaining of this issue with this card (but you could use the website search feature to be sure). And what does "although there appears to be a problem with the video card" mean? It would likely help if you would give other people any error mesage or other information that you have that led to this statement.
