Ok, here is the latest:

I downloaded and installed the Knoppix 5.1.1 CD version. That seems to be working on my D610 computer. The graphics screen comes up just fine and I can get started using KNOPPIX. Thanks for the heads up on this.

I still have the issue of not finding the KNOPPIX filesystem when I try to boot on my E6500. I was wondering (if it is truly having trouble finding the CD drive) if I could try and create Knoppix on a USB drive and that could possibly help my E6500? Am I just hoping for something that won't work? How do I get the Knoppix system to recognize my CD with the Knoppix filesystem? It can find and read the CD when it boots up to the boot screen, why can't it read it when Knoppix loads further down the line?

Thanks.
