The exception indicates that go32 doesn't know how to translate the 32-bit request to the correstponding 16-bit request. If you want to teach it how, you must modify go32/exphdlr.c. You will also not be able to directly call any real mode address from go32, so the far pointer you get will be almost useless. DJ
