Abstract: Methods and systems are disclosed that initiate, during a power-on self-test of a computer system, a pre-registered handler for accessing, modifying, or a combination thereof one or more registers within a basic input output system (BIOS) of the computer system. A request to access, modify, or a combination thereof at least one register of the one or more registers within the BIOS is received during runtime of an operating system of the computer system. The request with the pre-registered handler is processed to access, modify, or a combination thereof at least one register of the one or more registers within the BIOS corresponding to the request. A response to the request is provided based on data from the at least one register obtained by the pre-registered handler.

Abstract: A system and method that allows debugging data to be stored without slowing down initialization is disclosed. The system includes a processor, a firmware read only memory (ROM), and a first memory device coupled to the firmware ROM. The firmware ROM can be a BIOS ROM. The first memory device is configured to store debug information from the firmware ROM prior to running an operating system on the processor. Having the firmware ROM store the debug information on the first memory device allows debug information associated with the firmware to be easily accessible without needing a debug firmware or a cable to receive outputs of the debug firmware.
