I doubt there has been any update to pxechn.c32 for UEFI support. Maybe 
Gene can confirm.

If you are trying to chain to another efi binary / image, perhaps this 
[1] PoC might help? If not for the exact goal, perhaps as an initial 
base so to make some new c32 module for UEFI systems?

@Developers, please consider using 8.3 file names format for c32 files 
instead of such a long file name.
If possible, also use short names for source files too. TIA.

Regards,
Ady.
