Abstract: A system and method for providing system data during a power-on routine of a basic input output system. A controller is powered with an independent power source and accesses the system data. A power-on self-test routine is performed via a basic input output system. The fastest available interface of a plurality of interfaces between the basic input output system and the controller is determined. One of the plurality of interfaces is selected. The system data is sent from the controller to the basic input output system via the selected interface during the power-on self-test routine.
