You know, I hadn't thought of that, but memtest86 does work without needing a separate partition. You're right. So obviously it can work. Les, if I were you, I'd check out rom-o-matic and see what formats it will generate for you. Also, install memtest86 and see how it modifies grub.conf and where it installs the image. > > > As far as I can tell, no.

I stand corrected. Obviously grub is far more flexible than I was originally thinking. Jonathan
