If you have created an image aimed to a floppy, then something like:

dd if=<type>.image of=/dev/fd0[u<size>] bs=512

will be more than enough... if you have formated the floppy correctly
using \`superformat' to be found in \`fdutils' package.

For El Torito floppy emulation :

mkisofs -b <image> -c boot.catalog -o raw.iso <dir>

And for El Torito Hard Disk emulation:

mkisofs -b <image> -hard-disk-boot -c boot.catalog -o raw.iso <dir>

Enjoy!
