Int 67H [EMS 3.2] Function 4EH (78) Subfunction 01H Restore page map

Restores the page-mapping state of the expanded memory hardware using the information in the specified buffer.

Call with:

AH = 4EH

AL = 01H

DS:SI = segment:offset of buffer (see Notes)

Returns:

If function successful

AH = 00H

If function unsuccessful

AH = error code

Notes:

The buffer contains information necessary to restore the state of the mapping registers from a previous call to Int 67H Function 4EH Subfunction 00H or 02H. The format of the information may vary.

Unlike Int 67H Function 48H, this function does not require a handle.
