Hello, Jeffery.

There are two isos you might have used, one is for adriane as default, and one is not.
Both have spoken introduction and shut-down messages.
The non-adriane version will start-up in adriane if you use input 'knoppix adriane' at the boot prompt;
you don't need to edit th cfg file to get into adriane mode.

It's going to be a long hard slog for you making a CD version out of the DVD.
Somewhere along the line you may delete some code needed by one of the programs you want to keep.
It might help for you to petition Klaus K personally to see when you might expect a bona fide Knoppix 7.6 LiveCD.
