What OS are you using?

On Linux:

   Mount the floppy as a block device and do what you want.
   [I know no details what-so-ever]
   Look at ount and dd.


On Windows:

   - Figure out the format of a "disk image".
   - Use Scheme to make the image file.
   - Use the utility rawrite.exe to write the image to disk
     (on the Redhat CD - to make Linux boot disks on DOS/Windows)
