Technical Field

[0001] This invention relates to the field of computer application technology, and in particular to a method and apparatus for customizing a basic input / output system. Background Technology

[0002] With the rapid development of computer technology and the Internet and Internet of Things industries, competition among computer product manufacturers is becoming increasingly fierce, and user demands are becoming more diversified. To better enhance product market competitiveness and customer satisfaction, customization needs have emerged, requiring manufacturers to propose and implement customized production models. For example, in the current production process of desktop computers, it is sometimes necessary to update the product to a customized Basic Input Output System (BIOS) version based on user customization requirements. This customized BIOS version may include customer logo information, customized settings options, and customized model information.

[0003] When developing custom BIOSes, firmware engineers need to write a large amount of redundant code, compile versions according to customization requirements, and distribute them to the production line. This involves distributing and controlling numerous different versions, increasing the workload of version control and leading to a growing number of version distributions, which is detrimental to version management. Simultaneously, in actual production, the production line produces multiple products with different requirements, also involving the management of numerous different BIOS versions. Currently, manual control and inspection are required, which is prone to omissions, leading to missed flashes, flashing the wrong version, and sometimes even flashing failures that prevent booting, severely impacting production efficiency and customer experience.

[0004] Therefore, there is an urgent need to propose a basic input / output system customization method and device that can help optimize the development process of customized BIOS, achieve compatibility with product versions on the same platform, and simplify code development.
