You could start by looking at the code for DXEs in DJGPP; this might even
provide a base for you to extend. AFAIK they were only hacked together to
the stage where the floating point emulation could be loaded at run-time,
and there are severe restrictions on what you can/cannot do in the .dxe
files (I think C library routines are not allowed, for instance). But it
might give you some ideas for how to make a start.

You could look around Microsoft's homepage; they have examples and
descriptions of their file formats which again might give you some ideas
for where to start.
