This is correct: PC/104 is only ISA. The ACCES 104-IDIO-16 board is a
PC/104 stackable GPIO board, whose port address is configured via
physical jumper switches on the board; it is not "hotpluggable." For
this reason, the CONFIG_104_IDIO_16_BASE option should be set to the
same port address physically configured on the board.
