Get the latest GRUB sources, build the info documentation, and read
docs/multiboot.info.  Look at the ``Example OS code'' node (under
Examples), and you'll see how to build your kernel with a multiboot
header in it.

If running mbchk on your kernel succeeds, chances are it will be
successfully loaded by GRUB.

GRUB doesn't actually understand generic ELF or a.out, only files with
a Multiboot header, and some special cases (like the Linux kernel
format, *BSD, and chainloading).

Good luck,
