Okay, I managed to install it with ADRIANE - there is a option in the settings menu I was not aware of. When I use this option, it installs Knoppix with ADRIANE activated.

Now the question:
should I go for a USB stick installation or a hard disk installation? Do they have the same "problems", or is the USB stick installation more compatible?

Or maybe: is there a way to "emulate" the DVD, so that Knoppix ADRIANE boots from HD but itselfs thinks, that it is the DVD version? Well, a problem might be, that there should be no other operating system in use - so Knoppix ADRIANE only.
