Oh dear, you are trying to get past quite many thingies here.. ;)

First, I am not sure that the Sb16 emulation under Bochs works
perfectly, I never tried it over here but I have my doubts on it.  As to
where to begin with loading an OS under Bochs (we normally call it a
guest os), you could try to do it under a real pc first, something
running linux (to get you familiar), then it would be a simple matter of
getting bochs to compile for DCLinux.

It really isn't that hard, you use a .bochsrc file which points to your
bios images and to your disk images.  You then start bochs.

Have you actually ever try running bochs on your PC? that might be a
good thing to try, that would at least give you a taste of what is
possible and what isn't.
