INT 62 u - FGDRIVER v3.03 - "FG_ALLOCEMS" - CREATE LOGICAL VIDEO PAGE (EMS)
        AX = 0002h
        BX = page number (0001h-003Fh)
Return: AX = status (see AX=0001h)
Notes:  For FGDRIVER v1.10, this function was "FG_TESTMODE" (see AX=00A7h);
          "FG_ALLOCEMS" was AX=009Eh
        You must first call "FG_INITEMS" (see AX=004Ch) before using this
          function
        The only operation which is allowed on logical pages is "FG_COPYPAGE"
          (see AX=0012h)
