Look at http://www.tldp.org/HOWTO/Bootdisk-HOWTO/
, if you want to make your own bootdisk.
I have not tried Fedora, but I think that there should be a bootdisk image on one of the install-cd's. Try to type:
dd if=/path/to/bootdisk-image of=/dev/fd0
. This should copy the image over to a floppy.
Hope it could help.
