<p><b>Return:</b><br>CX = status (most subfunctions)
(E)AX and/or (E)BX contain return values, depending on function
</PRE>
<p><b>Notes:</b>
Called by DPMS.EXE and EMM386.EXE.
This API is only available if AX=12FFh/BX=0EDCh returns successfully;
because the request is handled on the initial trap to the memory
manager caused by INT instructions, this API must be invoked with
an actual INT 2F instruction instead of some simulation such as a
far call to the address in the interrupt vector table
