Will this help? ( from the GRUB info pages ) When booting from it
you can edit the grub stanza on the fly, if necessary, to start
from your desired vmlinuz, initrd, etc located on the hard drive.

3.1 Creating a GRUB boot floppy
===============================
To create a GRUB boot floppy, you need to take the files `stage1'
and `stage2' from the image directory, and write them to the first
and the second block of the floppy disk, respectively.
*Caution:* This procedure will destroy any data currently stored on
the floppy.
On a UNIX-like operating system, that is done with the following
commands:
# cd /usr/share/grub/i386-pc
# dd if=stage1 of=/dev/fd0 bs=512 count=1
1+0 records in
1+0 records out
# dd if=stage2 of=/dev/fd0 bs=512 seek=1
153+1 records in
153+1 records out
#
The device file name may be different. Consult the manual for your
OS.
