The map list contains the number of mappable segments in the first word, followed by the segment addresses of the mappable memory regions (one segment per word).Saves the state of a subset of the expanded memory page-mapping registers in the specified buffer.
Call with:
AH = 4FH
AL = 00H
DS:SI = segment:offset of map list (see Notes)
ES:DI = segment:offset of buffer to receive mapping state (see
Notes)
Returns:
If function successful
AH = 00H
and buffer filled in with mapping information (see Notes)
If function unsuccessful
AH = error code
Notes:
The map list contains the number of mappable segments in the first word, followed by the segment addresses of the mappable memory regions (one segment per word).
To determine the size of the buffer required for the mapping state, use Int 67H Function 4FH Subfunction 02H.
