dmidecode：找出硬件细节，而不打开电脑机箱
版本1.0
作者：Falko Timme
dmidecode是一种用于以人类可读格式转储计算机的DMI（有些说SMBIOS）表格内容的工具。 该表包含系统硬件组件的描述，以及序列号和BIOS修订等其他有用的信息。 感谢这个表，您可以检索这些信息，而无需探测实际的硬件。
看一眼
man dmidecode
找出所有选项。 最常见的选项是--type开关，其中包含以下一个或多个关键字：
bios, system, baseboard, chassis, processor, memory, cache, connector, slot
您还可以指定以下一个或多个数字：
Type Information
----------------------------------------
0 BIOS
1 System

32 System Boot
33 64-bit Memory Error
34 Management Device
35 Management Device Component
36 Management Device Threshold Data
37 Memory Channel
38 IPMI Device
39 Power Supply
每个关键字等同于一个类型号列表：
