USB booting :: LiveUSB

I do realize that some may be tired of the same old questions,yet after extensiv searching I still can't find the answers Im looking for.(Im addicted to the search feild:)

I've tried all the other sugesstion in other post and still need help. How do I make a LiveUSB DSL3.0.1? Im using an old thinkpad385xd. As you all may know these don't have usb boot options in bios. I have to use a boot floppy since I also don't have a cd burner. At this point I have the bootfloppyusb.iso on a 1.44 floppy and still have no idea of how to set up the USB Im using a Muvofm .mp3 player wich I understand that someone using a similar player(muvu nana) that works with their dsl system) This USB has 256mb capicity. What do I need to make this a dsl liveusb? Thanks
in advance for all the help

since you have the boot floppy, all you need is the KNOPPIX image and put it in a /KNOPPIX/ directory of the usb partition.

you can extract it from the .iso or from the the zip file of the embedded version.
