Haven't tried that yet although sounds interesting
How to build your own Grub floppy.
Take a floppy disk (fat or ext2)
...
Run grub from a linux shell.
Type the following commands:
root (fd0)
setup (fd0)
quit
And you're done. You do have the grub floppy.
Did that and it worked fine, thanks

dd if=grub-0.97-i386-pc.ext2fs of=/dev/fd0
I also tried that and that also worked, thanks also.
In case anyone else tries this, a couple of comments:
. the version downloaded from
ftp://alpha.gnu.org/gnu/grub/grub-0.97-i386-pc.ext2fs has fewer subcommands
than the one made by copying my own grub directory. I don't remember which
were missing and all the ones I need are there so not important for me
. You may find that when you test your brand new grub boot floppy, (which
you of course will always do), that it fails when trying to read a file.
If so, get a newer/different floppy and try again. I had several such
failures on floppy disks which a running linux system could mount and read
all files quite happily, so I'm guessing that grub has very limited
error-handling for floppy disks - e.g. maybe it cannot handle reallocation
of bad sectors or something like that?
