Can you load into RAM?  My first inclination is to load into RAM
for debug purposes to avoid cycles on Flash.  Or you could simply
put the image to debug into flash with flashu.exe.

The question is what format does flashu.exe expect.  The make-exe
rule in the custom file is intended to link the application and
transform it into the download format.

You will probably have to do a new BSP for this one.  Do an inventory
on the board, address map, identify areas of PC compatability where
you can use the i386/shared drivers.

Then I would probably start with either i386ex or ts_386ex.  Personally
I like to figure out where each piece of a new BSP is coming from and
then assemble, massage, compile.  Homework before hacking.

An old cast away PC would be easier. :)
