This probably means that you should use the real-mode interface, since
mixing 16-bit code with 32-bit code in the DPMI environment is tricky,
if not impossible.

So I think you need to forget about 16-bit PM selectors, and instead
work via the real-mode interface, using the transfer buffer,
__dpmi_int, and the other functions that allow to invoke real-mode
procedures.  If you have problems with doing that, please post
specific questions.
