Management method of graphics card driver under UEFI (Unified Extensible Firmware Interface)

The invention is applicable to the technical field of graphics card drivers, and provides a graphics card driver management method under a UEFI (Unified Extensible Firmware Interface) architecture, which comprises the following steps of: establishing a function lookup table, looking up graphics card equipment, reading flash ID (Identity), and updating a graphics card driver. When needed, the display card drive program can be erased, read and check and use help. According to the invention, multiple flash chips are supported, and adaptability and universality are realized; the verification, reading, erasing, writing and other methods of the display card driver are realized, the rapid read-write mode with the highest priority can be automatically identified and matched, and the read-write efficiency is improved; and the system can be freely combined and used according to requirements, is flexible to operate, is not easy to make mistakes, does not depend on an operating system or a kernel, and is high in adaptabi
