I downloaded knoppix and have been trying to get it to work

I downloaded the iso iamage using bittorrent

i burned the image on to a CD-r using nero express
-data
----bootable data disk
--------added the file gamesknoppix3.7-0.2-en.iso

burned without a problem

booting from cd/dvd drive
i get a dos prompt and a few files
don't know what to do from here
(i open a file call wmmbu (i think ) but it was in german so i just closed it )
i can see the ISO image on the dvd drive
please help
Thanks

I have also tried just coping the iso file to cd and then using that (w/o Bootable data cd settings ) that just ended up booting in to xp

I am running win xp on a dell p4 3.0g w/256mb
