Abstract
A riser card with an interface on a motherboard can reduce the overall cost of an electronic system as well as simplify upgrading the features provided by the riser. Implementation costs can be reduced for components that may otherwise require shielding in order to prevent electromagnetic interference if the component were located on the motherboard. Other components can also be simplified if located on a riser rather than the motherboard. The riser card described herein provides functionality so that an operating system controlling the riser card can load the appropriate driver software thereby simplifying operation of the electronic system. In one embodiment, a BIOS stored in a memory on the motherboard interacts with a memory on the riser card to obtain information related to functionality of the riser card and to properly initialize the components of the riser card.
