How do you link? If you use GNU ld you need to mess with linker scripts.
I've written small .com files using gas and ld. I've also recoded
FDXMS using gas and ld.

I remember it was hard to get rid of the extra zeroes before the real
code. (Bug in ld, perhaps?) I think I just skipped .org 0x100 and
instead used nothing or .org 0 and let ld with the correct script deal
with it.


If you wait and are lucky I might dig up some of what I've written.
