DSL Embedded :: How to get into system?

I have a system size of paper back book. I can boot only by net, USB floppy or USB stick made to look like a floppy, ( not HDD) or internal 512meg FLASH IDE hard drive.
I have puppy super floppy that boots to ram. Anyone write a program to run on puppy linux to take DSL files from 2nd USB stick and install in 512meg FLASH drive?????
