I really like that idea, and not the most skilled with Linux. Basically, how would I write that as a simple script (Like a dos .Bat file) save it to my thumb drive and when I want to switch from CD to Thumbdrive.

And perhaps I'm asking to much on this thread, but would it be possible to install programs on the the thumbdrive and use them when I switch to the thumbdrive with out remastering the knoppix.iso file?
