Innovation Solution
The implementation of an option ROM (OPROM) data structure that dynamically updates the firmware image by modifying OPROM identifiers and pointers based on hardware configuration changes, allowing for the addition or removal of OPROMs as hardware devices are added or removed, and utilizing a data structure signature to locate and manage these changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If firmware is customized for specific hardware devices by adding or removing option ROMs, then the firmware supports vendor-specific hardware components, but the customization process consumes time and resources
Solution Approach 1:
The patent implements dynamic firmware customization by allowing the firmware image to be automatically updated based on detected hardware configurations. The system dynamically adds or removes option ROMs from the firmware image according to which hardware devices are actually installed, eliminating the need for static pre-customization for each possible hardware combination.
Solution Approach 2:
The firmware system performs self-customization by automatically detecting installed hardware devices and configuring the appropriate option ROMs without external intervention. The firmware image updates itself based on the hardware configuration, making the customization process autonomous and eliminating manual firmware customization steps.
2Adaptability or versatility

3Adaptability or versatility
If the firmware image contains multiple option ROMs for different hardware configurations, then the firmware can support various hardware devices, but the firmware image size and complexity increase
Solution Approach 1:
The patent segments the firmware image into modular components, with option ROMs organized in a structured data format that allows individual selection. Each option ROM is a separate, independently manageable unit that can be easily added or removed from the firmware image based on hardware detection, reducing the complexity of managing large firmware images.
Solution Approach 2:
The patent implements dynamic firmware customization by allowing the firmware image to be automatically updated based on detected hardware configurations. The system dynamically adds or removes option ROMs from the firmware image according to which hardware devices are actually installed, eliminating the need for static pre-customization for each possible hardware combination.
4Reliability
If manual firmware customization is performed for each hardware configuration, then the firmware accurately supports installed hardware, but the process is time-consuming and resource-intensive
Solution Approach 1:
The firmware system performs self-customization by automatically detecting installed hardware devices and configuring the appropriate option ROMs without external intervention. The firmware image updates itself based on the hardware configuration, making the customization process autonomous and eliminating manual firmware customization steps.
Solution Approach 2:
The system uses hardware detection feedback to automatically configure the firmware image. By detecting which hardware devices are installed and using this information to determine which option ROMs to include, the system ensures accurate firmware-hardware matching while eliminating manual customization steps.

AI summary
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.
