Abstract
Methods, systems, apparatus, and computer-readable media for dynamically updating a computer system and firmware image utilizing an option ROM (“OPROM”) data structure. When a hardware configuration of a computer system is modified, a corresponding OPROM within the firmware image is modified. An OPROM data structure is created in a firmware image. Each data structure contains identification data corresponding to the data structure as well as an OPROM entry for each OPROM within the firmware image. Each OPROM entry has identification data pointing to the corresponding OPROM and identification data corresponding to the OPROM and associated hardware device. Firmware program modules utilize the OPROM data structure to identify the correct OPROMs for use with the computer system hardware configuration. An application searches for a unique signature associated with the OPROM data structure and modifies OPROM entries as hardware devices and associated OPROMs are added to and removed from the computer system.
