Yes: look at http://www.elinos.com/demos/busybox.html. Grab the busybox.flp
image from there and write it to a floppy with "cat busybox.flp >/dev/fd0".
BTW: This floppy uses syslinux, not lilo (it's better suited for floppy disks).
The disk has an MSDOS filesystem, thus you can mount it and look at it. The file
busybox.tgz on the disk contains a gziped tar image of the root filesystem
(which lives in a RAMdisk). Thus you can easily extract it, make modifications
and put together your own version with tar.
