Hi.
Go to http://people.freebsd.org/~picobsd/picobsd.html and download the
BootFORTH demo
(floppy image)
(Direct link: http://www.freebsd.org/~picobsd/bootldr.bin )


Copy it to a floppy (using dd(1)) and you have a boot floppy that you
can mount (it has a ufs filesystem) and customize.
You can also create a bootable floppy manually by following the
instructions in The Handbook, but the picobsd floppy image is a great
starting point for this kind of thing.
