The Knoppix DVD boots into Knoppix by default.

To boot into the screen reader it is necessary to give the following cheat code when booting:

adriane

You can do this during the boot process by typing adriane at the boot prompt or by selecting adriane from the boot list of options.

A better way would be to create a modified DVD whereby the isolinux.cfg file in the /boot/isolinux directory is changed.

All that is necessary is to change one line at the top of the file.

Change
DEFAULT knoppix
to
DEFAULT adriane

If you ever make a poor man's install one could also change the boot configuration file to add the necessary cheat code to the default option.
