UEFI Option ROM Interface Generation for Flexible Device Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack flexibility in configuring and managing configuration interface options for external devices, leading to highly customized static options and a tight coupling between configuration interfaces and firmware, requiring synchronous modifications.
Innovation Solution
A method is provided for generating configuration interfaces by merging a UEFI driver and a configuration interface file, using a file parser to dynamically parse the configuration interface file, and creating options for a UEFI setup menu, allowing adjustments through configuration interface information stored in the external device's firmware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If configuration interfaces are highly customized and statically configured, then specific device requirements are met, but flexibility and adaptability are reduced
Solution Approach 1:
The patent implements dynamic configuration interface generation by merging the UEFI driver with configuration interface information and using a file parser to dynamically parse and create configuration options in the UEFI setup menu, allowing the system to adapt to different external devices without requiring static preconfiguration for each device type
Solution Approach 2:
The UEFI driver is designed to perform multiple functions: it not only drives the external device but also contains embedded configuration interface information that can be parsed to generate device-specific configuration options, making the driver a universal component that handles both device operation and configuration presentation
2Stability of the object's composition
If configuration interfaces are tightly coupled with firmware, then integrated control is achieved, but modification requirements increase development complexity
Solution Approach 1:
The configuration interface information is segmented and embedded within the UEFI driver as a separate component that can be independently parsed and modified. The file parser extracts configuration options from this embedded information, allowing modifications to configuration interfaces without requiring changes to the entire firmware structure
Solution Approach 2:
The configuration interface information acts as an intermediary layer between the UEFI driver and the setup menu display. This intermediate representation can be parsed and processed without modifying the underlying driver code, reducing modification complexity while maintaining integrated control
3Ease of manufacture
If configuration interface options are statically defined, then implementation simplicity is maintained, but adaptability to different devices is reduced
Solution Approach 1:
The system transitions from static configuration definitions to dynamic configuration generation. The file parser dynamically parses the configuration interface information embedded in the UEFI driver based on the actual external device detected, generating appropriate configuration options at runtime rather than requiring pre-defined static options for all possible devices
Data Source
AI summary
A method for generating configuration interfaces is provided. The method comprises loading a UEFI Option ROM driver of an external device through a UEFI of a host device, where the UEFI Option ROM driver is generated based on a UEFI driver and a configuration interface file; dynamically parsing the configuration interface file of the UEFI Option ROM driver using a file parser within the UEFI Option ROM driver to obtain a parsing result, and creating configuration interface options for a UEFI setup menu of the host device based on the parsing result. By utilizing the above method, users can flexibly configure and manage the interfaces of the external device.
