IOB (In/Out Board) controls input/output, drivers and input/output connections. The IOB is
part of the EGB expansion board.
You can only install two of the optional interface boards (IEEE1284, IEEE802.11b,
Bluetooth, USB Host and Gigabit Ethernet) at the same time. (You can not install
IEEE802.11b and Bluetooth at the same time.)
The controller connects to the EGB through the PCI Bus (Peripheral Component
Interconnect Bus).
