If a support card is attached to the main board, the on-board SMSC9118 LAN controller is available. It must be kept in reset state for a while on start-up. When the board is kicked via a debbuger rather than pushing the hardware reset button, on-board chips are not reset; in this case the reset signals should be asserted by software.
