AH = 83h: Get/Set Page Map

This function is composed of four subfunctions which perform general saving and restoring of the page mapping state. The state is saved to or restored from a save array provided in the calling program. One of these subfunctions is used to determine the required length for the array.

These functions are intended to be used to save or restore the HP palmtop's page map state as a unit; the internal representation of the page map state should not be manipulated.
