sudo mkdir -p /mnt/floppy
sudo mount /dev/fd0 /mnt/floppy
The floppy is then mounted at /mnt/floppy, make sure you have a disk inserted when you mount it. You would also "sudo umount /dev/fd0" if you want to unmount it.
You can substitute /mnt/floppy for the mount-point of your choice. Hope this helped.
Sorry for my lack of experience with Fedora, I've only delt with RH in a console-only server environment and currently use Ubuntu/Debian for my workstation/server needs. I couldn't tell you what the green triangle means.
