charset="utf-8" The bit that is supposed to control if ISA IO ports are accessed with discontiguous addresses was not connected so it did nothing. We can now directly enable or disable the discontiguous region so allow the bit to function. This did not cause a problem so far as nothing seems to use this bit or discontiguous IO addresses.
