Dynamically updating a computer system firmware image
View Patent ↗Methods, systems, apparatus, and computer-readable media for customizing a computer system firmware image utilizing a firmware configuration data structure. At least one firmware configuration data structure is created in a firmware image. Each data structure contains configuration data stored within a data field. A data structure signature identifying the data structure is stored within a data field of the data structure. A pointer to the configuration data within the data structure is stored in at least one firmware program module. An application may search for a firmware configuration data structure according to the data structure signature and content signatures corresponding to specific data entries, retrieve the applicable data structure and data entry, and store modifications to data stored therein.
