I've not tried this but the thought is to use an awk/sed script in a knoppix.sh script to change those files mentioned earlier. You'd have to copy this to a floppy, usb dongle, or the systems HD but that would be it. You'd use the "knoppix myconfig=scan" boot codes but since theres no configs.tgz and just the knoppix.sh script, it's a quick boot and pretty much default.

You might be able to find the default audio volume file( from audio config setup ) and just create or change that to what it needs to be. It's the file created when you use the ControlCenter-Audio Settings.

It's not a "cheat code" only solution but should require just the knoppix.sh file.
