Abstract: Embedded computer based on X86 platform has been widely applied to many fields. There are a great amount of interest in speeding up the configuration of embedded BIOS, shortening the developing period, and discarding the old complicated BIOS configuration process. This paper brings forward a new design method of BIOS differing from tradition¬al ones——to separate codes of test and initialization from the data of initialization, which simplifies the maintenance of core codes during the configuration. The practice shows that the new method is more simple and effective in the embedded BIOS configuration.

摘要： 基于X86平台的嵌入式计算机得到了广泛应用。该文就如何有效提高嵌入式BIOS的配置速度，抛弃传统的BIOS开发的繁琐过程，缩短BIOS的开发周期，提出了一种不同于传统BIOS的新的设计方法——将POST过程的检测和初始化代码与初始化数据分离，以简化配置过程对核心代码的维护。实践证明，该方法使嵌入式BIOS的配置工作更加简单、高效。
