4.5 PC/104-Plus Bus
Expansion cards can be connected to the board using the PCI connector first introduced with the
PC/104-Plus standard. A maximum of four PC/104-Plus cards are supported.
The interrupt routing and the IDSEL signals for the expansion cards are specified in the PC/104-Plus
specification (see "Specifications and Documents", p. 12).
