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.
