Boot from Floppy

I have an old FJ B2131 that will only boot from FDD or HDD, and would like to try Linux. Having stumbled across Puppy, what I have seen of it so far, it looks great! I have managed to download V1 and have modified my DOS boot disc to load V1 Puppy from the CDRom (connected via PCMCIA).

Two Questions:

1. How do I get the Pup_410.sfs off the distro and get it to run under dos, or is there some other way of acheiving the same thing. I need to start from DOS (I think) to get the PCMCIA driver loaded to recognise the CDRom.
