Hi Rob, I would start a bit more at the meta level and research how kernels work. There are also many sites dealing with OS development (osdev is useful search term). It is quite instructive to see the first steps that happen after the machine boots (the boot loader mainly). Once you've really understood that and perhaps cobbled together your own simplistic test OS, you should be well on your way to dive into the FreeDOS kernel source.
