Grub floppy boot disk

[damonbrinkley]

I have a Grub floppy boot disk that works great for testing kernels but I have a question about the formats Grub can use. I've tried compiling to just binary and elf files on my own but I keep getting an Error 13: Invalid or unsupported executable format error when loading my kernel. I know this boot disk works because I've followed some tutorials and booted those kernels from this disk but can't seem to do it on my own. Are there any special compilations commands I need to use to make my kernel compatible with Grub? Thanks.

You need to built a multiboot header, have a look at http://osdev.berlios.de/grub.html for more informations...
