LOADING DPMI CLIENTS AND EXTENDED APPLICATIONS


            All DPMI  applications begin  execution in  real mode.    An
            application must  run first  as a  standard  real  mode  DOS
            program but it can switch to protected execution by making a
            few simple calls.

            DPMI does not define an executable file format for protected
            mode programs.   Instead,  programs must  provide their  own
            mechanism for loading and fixing up protected mode code.
