No, they are fundamentally incompatible.  (Borland 16-bit DPMI applications
expect more than just 16-bit DPMI, they also expect the DPMI to provide
DOS extension services).

Why do you have to do this?  DJGPP should automatically load CWSDPMI if
DPMI isn't present.  Making DRDOS DPMI work (or turning it off) should be

CWSDPMI -u should unload CWSDPMI and allow the other program to work OK.
It should run without DPMI in DOS mode - it may have it's own extender and
be more stable that way.
