Ok, I'm done. I used RaWrite for Windows (http://members.optusnet.com.au/atar/rawritewin.exe) to install Smart Boot Manager (http://members.optusnet.com.au/atar/sbootmgr.img) on a floppy under Windows. I ran knoppix using the floppy from other computer and not from my laptop (the program doesn't seem to read USB devices) and once in Knoppix I made the two floppies going to Knoppix -> Utilities -> Create bootfloppies for Knoppix. Finally I've got the floppies so I can run Knoppix anywhere (even form USB devices).

Hey, do you think this walk-around is worth? Wouldn't be easier to include two images of the floppies in the cd (removing some of the <lol>great</lol> games it comes with to make some room) ?

One more thing: how can I create images of the floppies?

Thanks for your time.
