AX = DE17h BX = function 0000h get current mapping context without setting nonzero set new mapping context to BX
Return:
BX = mapping context in effect before call
Notes: Mapping contexts determine conventional-memory addressability; setting a mapping context ensures that the associated program and data areas are in memory for access. Usable by drivers, TSRs and shared programs.. Caller need not be running under DESQview. This API call may be made from a hardware interrupt handler
