基于UEFI的SMBIOS设计与研究

Research and design of SMBIOS base on UEFI

为加速计算机固件中SMBIOS部分开发与定制化,提出了SMBIOS系统架构,将核心服务和数据表定制分离。设计了基于UEFI规范的实现方案,以协议的方式提供核心服务,并采用独立模块将该协议注册到UEFI系统;另一模块将调用核心服务,将已收集到的计算机系统信息,根据工业规范和定制化需求组织数据表内容。以定制化的数据表类型3为例,分别在UEFI Shell和Win32控制台中,采用调用Win32系统函数和WMI的方式查看了SMBIOS内容,表明了架构的可实现性,设计的的准确性和有效性。

To speed up the development and customization about SMBIOS in computer firmware, the SMBIOS system framework is proposed, the core services and structure table are separated by this framework. The implementation scheme based on UEFI standard is designed. Core services are provided as protocol and resisted to UEFI system by independent module. The SMBIOS structure table is constructed by the collected computer system information that satisfied the industrial standard and customized demands. Core services protocol will be called in order to construct the table in another independent module. Structure table （type 3） is customized for sample to do experiment. The test application that Win32 API or WMI being called in it is running in UEFI shell and win32 console environment demonstrate the SMBIOS table content. The example is presented to prove the realiz- ability of the framework and the accuracy and efficiency of the proposed design.
