I see. This has been very educational. In the initial post, I said that I have been trying to use a persistent disk image, but have been unsuccessful.

"KNOPPIX is an O/S that can be run from a CD on a Windows box, as long as you don't use the hard drive"

is very different than

"KNOPPIX is an O/S that can be run from a CD on a Windows box"

I will have to go somewhere else to find my solution.

Thank you all for your time.
