If it's Knoppix, then go to the KNOPPIX menu and choose Root Console. At the prompt, enter knx-hdinstall. You will be walked through installing it to the harddisk. You will need a partition for it, but I'm not sure how big. I think 2 gig. You might try www.knoppix.net
and look through the forums and FAQs.
Just realized that you weren't asking how to install it. Sorry. I'll try to read the post more carefully next time.
P.S. This situation raises the question: is there a way to delete one's own posts?
