Hmm, I need a little bit of help with this.  Does this grub entry look
correct?

title dos
        root (hd0,0)
        kernel /memdisk
        initrd /my_floppy.img

That means that both memdisk and my_floppy.img have to be in /boot/ in my
filesystem, right?  Where can I get memdisk?  "yum search memdisk" came up
with nothing.

Also, is it possible to have setup a ramdisk in this configuration?  Is that
done in the grub entry or in the floppy image?  It would be nice to boot
the floppy with memdisk, then unzip the files to some temp filesystem (i.e.
the ramdisk).  I guess I would have to do that in the dos floppy image
because the ramdisk would have to be mounted to a dos drive letter (i.e. r
\) and that is dos specific...?

Thanks for the help.
