Anyone who has ever tried to add a modem- or network-card to a PC knows that such an undertaking may produce unwanted results and can take more time than expected. To achieve cost savings from high volume production, the add-in board is designed to be logically compatible to a large variety of motherboards from various vendors. This flexibility makes it necessary to configure the board for its operating environment before it is ready to function. To perform the configuration one needs two pieces of information: sufficient knowledge of the system that the board is expected to reside in and knowledge of the board itself. Once the suitable settings are determined one needs to set jumpers or flip switches on the board. This completes the tricky part of the hardware installation.
