ok. I downloaded a cd ISO image of knoppix. I didn't have any blank cd's but I only had blank DVD's. So i burned the image to the DVD, and booted and it worked perfectly. My question is, is it possible to add applications to this, as is it's only using 700 MB when i can fill up 4 gigs more. I would like to fill up the remaining space of 4 GB with programs, and get them to work, and become installed with the O/S when i boot. If anyone has any ideas or coments please post!
