AX = 0014h
BX = source page number (0000h-003Fh)
CX = destination page number (0000h-003Fh)
Notes: the FGDRIVER functions are rearranged with each major release, but
their parameters do not change (see #3145)
If both source and destination pages are logical pages, they must both
be located in the same type (conventional, EMS, XMS) of memory
