SMBIOS
SMBIOS(System Management BIOS)是主板或系统制造者以标准格式显示产品管理信息所需遵循的统一规范。
DMI (Desktop Management Interface, DMI)的主要组成部分是Management InformationFormat (MIF)数据库。这个数据库包括了所有有关电脑系统和配件的信息。通过DMI，用户可以获取序列号、电脑厂商、串口信息以及其它系统配件信息。
在介绍什么是DMI之前，先说说SMBIOS (System Management BIOS，SMBIOS)的概念。 SMBIOS是主板或系统制造者以标准格式显示产品管理信息所需遵循的统一规范。 DMI (Desktop Management Inte***ce, DMI)就是帮助收集电脑系统信息的管理系统，DMI信息的收集必须在严格遵照SMBIOS规范的前提下进行。
SMBIOS和DMI是由行业指导机构Desktop Management Task Force (DMTF)起草的开放性的技术标准，其中，DMI设计适用于任何的平台和操作系统。 DMI充当了管理工具和系统层之间接口的角色。它建立了标准的可管理系统更加方便了电脑厂商和用户对系统的了解。为了提供更为友好的用户工作环境，AOpen开发了实用的WinDMI工具，它采用Windows界面，能够用于多款AOpen主板，完全兼容 Windows 98SE/98/2000/XP操作系统。 WinDMI分为几种功能，首先，默认的[Normal
Mode]功能让用户可以获取包括BIOS、操作系统、主板、内存、扩展槽及扩展接口的所有详细系统信息。 第二种功能为[Dump Memory]，它可以让用户转储内存数据，因为它显示了当前DMI的结构数据，所以可以帮助高级用户及软件设计人员处理内存数据。此外，对DMI结构有兴趣的用户也可以使用此项功能进行初步的问题诊断。第三，WinDMI还可以让用户以普通或raw模式保存DMI数据，如果用户需要保存DMI信息，只需按下[Save As]即可。此项功能会在用户指定的文件夹下创建一个 .txt文件，用户就可以在此文本文件中找到所有所需的系统信息。
