Dynamic Firmware Configuration via Data Structure Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of firmware customization for computer systems is time-consuming and resource-intensive, requiring OEMs to return customized motherboards to manufacturers for firmware reconfiguration, which involves modifying the firmware image and source code, a process that is inefficient and laborious.
Innovation Solution
The implementation of firmware configuration data structures and program modules that allow for dynamic updating of firmware images without modifying the program modules, enabling customization by OEMs prior to flashing, using data structure signatures and pointers to reference configuration data within the firmware image.

Engineering Contradiction Analysis
1Adaptability or versatility
If firmware image is customized by returning to manufacturer for reconfiguration, then firmware can be adapted to specific hardware configurations, but the process consumes significant time and resources
Solution Approach 1:
The firmware image is segmented into program modules and configuration data structures. The configuration data structures are further divided into data fields that can be independently modified. This segmentation allows OEMs to customize only the configuration data portion without affecting the program modules, enabling rapid customization without full firmware reconfiguration.
Solution Approach 2:
The configuration data is extracted from the firmware image into separate, modifiable data structures. This extracted configuration data can be customized by OEMs using tools that read and modify these structures without requiring manufacturer intervention. The program modules retain pointers to these externalized configuration structures, maintaining functionality while enabling independent customization.
2Adaptability or versatility
If firmware image is customized by returning to manufacturer for reconfiguration, then firmware can be adapted to specific hardware configurations, but resource consumption increases due to multiple transfer and modification cycles
Solution Approach 1:
The firmware image is prepared in advance with configurable data structures and pointers that enable future customization. The program modules are compiled with placeholder pointers that will reference the final configuration data. This preliminary setup allows OEMs to perform rapid customization by only modifying the configuration data portion, eliminating the need for multiple manufacturer-OEM transfer cycles.
Solution Approach 2:
The configuration data structures serve as templates or copies that can be independently modified. OEMs can create customized versions of the configuration data without affecting the original firmware image or program modules. This copying mechanism allows parallel development and testing of different hardware configurations without resource-intensive reconfiguration cycles.
3Adaptability or versatility
If firmware source code is modified for hardware configuration changes, then firmware can support customized hardware, but the complexity of modification increases
Solution Approach 1:
Configuration parameters are extracted from the firmware source code into separate data structures. The program modules contain only pointers to these external configuration structures rather than hard-coded values. This extraction eliminates the need to modify program source code when adapting to different hardware configurations - only the configuration data structures need to be updated.
Solution Approach 2:
Configuration data structures serve as intermediaries between the program modules and hardware specifications. Instead of directly modifying program code to adapt to hardware changes, OEMs modify the intermediary configuration structures. The program modules automatically adapt through their pointers to these updated configuration structures, reducing modification complexity.
Data Source
AI summary
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.
