A good book about C would probably help (though unlikely to cover the
DOS memory model stuff). _C in a Nutshell_ seemed pretty good, from
what I could gather. But I normally hate books, so here's a site with
some good online references:


Also news://comp.os.msdos.programmer has a few super experienced
people, so you could also ask specific questions there (and here too,
of course).

Otherwise, the only real way to get familiar with the kernel is
probably just to build it yourself and poke around. Grab OpenWatcom
and NASM, then grab the shell and kernel sources.
