Correct, the EMX program requires RSX to act as an interface between
the program and the DPMI server. A DJGPP program includes this interface
code in the startup library.

Assuming you don't have a DMPI server loaded. If you did you would need
a RSX.EXE running. (At least the last time I checked EMX.EXE didn't
support DPMI)

True. Because

The only difference is whether EMX.EXE or RSX.EXE is providing the
protected mode interface. EMX.EXE will not run under DPMI. It
requires more direct access to the machine. RSX.EXE is really just
a version of EMX.EXE written for DPMI.
