I don't know anything about grub mind you, so that might not be feasible, but if I was using Lilo that's how I'd do it. > Would it be just be easier (and possibly more reliable) to have a floppy > kernel to boot off of in case of disaster with my boot drive? I happen to think that boot floppies are always a bad idea.
