We add a syslinux floppy disk type using parts of the genliso script. This floppy image cat be dd'ed to a physical floppy or used in instances where a virtual floppy with an mountable DOS filesystem is useful. We also modify the genliso script to only generate .liso images rather than creating images depending on how it is called. Signed-off-by: Michael Brown <mcb30@etherboot.org>
