Automated bios platform configuration system
A BIOS platform configuration system includes a BIOS coupled to hardware subsystems. During initialization operations, the BIOS communicates with each of the hardware subsystems and retrieves respective hardware subsystem information that is associated with each of the hardware subsystems and that describes at least a portion of a communication route between that hardware subsystem and at least one other hardware subsystem. The BIOS then combines the respective hardware subsystem information that is associated with each of the hardware subsystems to generate configuration information that describes complete communication routes between each of the hardware subsystems, and configures at least one of the hardware subsystems using the configuration information. In a specific example, the configuration information may provide a processing subsystem/chipset initialization table that is used initialize a processing subsystem/chipset in order to allow it to communicate with a device connected to a planar subsystem/motherboard that includes the processing system/chipset.
