I love getting way ahead of myself! I've only just started learning assembly, but it got me thinking about producing an operating system! Because everything's at such a low level and .asm is insanely fast in comparison to higher level languages it seems the ideal language to use for a lot of the very low-level OS stuff. So my actual question is how do I make a floppy disk bootable (in that a machine with no OS installed can start from it)?
