> What is a DPMI Server exactly ?

DPMI is an acronym for DOS Protected-Mode Interface.  It is a special
API, implemented as a bunch of functions of software interrupt 31h,
which allow protected-mode programs to run on top of real-mode DOS and
call DOS and BIOS services.  The DPMI server is a special software
that hooks interrupt 31h and provides the DPMI services.

Many modern PC-based operating systems (Windows is one of them)
include a DPMI server as their integral part.  DJGPP provides a free
DPMI server called CWSDPMI for those users who run on plain DOS and
don't have a commercial DPMI server installed.

All this, and much more is explained in the following Web page:
