OTHER APIS


            In general,  any software  interrupt interface  that  passes
            parameters in  the EAX,  EBX, ECX,  EDX, ESI,  EDI, and  EBP
            registers will  work  as  long  as  none  of  the  registers
            contains a  segment value.   In  other words,  if a software
            interrupt interface is completely register based without any
            pointers, segment  register, or  stack parameters,  that API
            could work under any DPMI implementation.
