Pre-Boot Firmware GUI via VFR Parsing for Third-Party Apps

The patent introduces an intermediary layer that translates between the simple text-mode interface of third-party applications and the rich graphics-mode interface of the UEFI environment. This mediator enables third-party applications to inherit modern UI features without requiring them to be rewritten in graphics mode, thus improving ease of operation while maintaining compatibility.

The patent creates a universal interface framework that allows third-party firmware applications to access multiple interface modes (text-mode and graphics-mode) through a single standardized API. This enables one application to benefit from both the simplicity of text-mode and the richness of graphics-mode interfaces, improving ease of operation without proportionally increasing complexity.

The patent implements dynamic execution permissions that allow third-party applications to run at different boot phases based on their specific requirements and system state. Rather than imposing static restrictions, the system dynamically evaluates whether an application can safely execute at a given phase, thereby increasing adaptability while maintaining reliability through conditional approval.

The patent changes the parameter of application execution timing from a fixed restriction to a flexible parameter that can be adjusted based on application needs and system conditions. This allows third-party applications to specify preferred execution phases, and the system to grant permission based on evaluated parameters, thus improving versatility without compromising stability.
