how can I make a boot floppy disk?

["mustafa" <mushk45 myrealbox com>]

I just finished installing fedora 3, I didn't install a boot loader, how can I make a boot floppy disk?
I saw this note from fedora 4 installation dcumentation:
"Your computer must have GRUB or another boot loader installed in order to start, unless you 
create a separate startup disk to boot from."
But the installation finished and it didn't ask me to make one!
also, I can burn a boot image on a cd, could that help
