I/O – Map
The board incorporates a fully ISA Bus Compatible slave interface. The drive capabilities
allow for up to four external PC/104 modules to be driven without external data buffers. The
accessible I/O area on the ISA-bus is 64Kbytes with 16 address bits, whereas the
accessible memory area is 16Mbytes with 24 address bits.
Certain I/O addresses are subject to change during boot as PnP managers may relocate
devices or functions. The addresses shown in the table are typical locations.

Note:
The usage of these I/O addresses depends on the choices made in the Evalue setup
screen. The I/O addresses are fully usable for PC/104 interface if the corresponding
on-board unit is disabled in the setup screen.
