http://linuxtoy.org/archives/dmidecode.html

Dmidecode 应该在主流的 Linux 发行版中都可以找到，因此你只需通过所用发行版的包管理器安装即可，如:

1

pacman -S dmidecode # Arch Linux
emerge -av dmidecode # Gentoo
aptitude install dmidecode # Debian/Ubuntu
yum install dmidecode # Fedora

不带选项执行 dmidecode 通常会输出所有的硬件信息，以下是在笔者机器上执行 dmidecode 后所得到的结果 (部分) :
