;
;   Define the EMS interrupt:
;
Ems         equ     67h

;
;   Now define the 3.0 EMS function codes.
;   These are 8 bit values which are loaded into
;   AH before calling the EMS interrupt.
;
GetStatus           equ     40h
GetPFA              equ     41h

;
;   Define the 3.2 and 4.0 EMS function codes:
;
;   Note that these are 16 bit values which
;   are loaded into AX prior to calling
;   the EMS interrupt. (These can be regarded
;   as an 8 bit function plus an 8 bit sub-
;   function.
;
;   The 3.2 codes:
;

SavePageMap32       equ     4e00h

SwapPageMap32       equ     4e02h
