Linux 查看硬件信息

 

Linux 查看系统硬件信息(实例详解)

 

区别ATAE R2 R3 R2+单板：

dmidecode -t 2|grep 'Product Name'

 

 

dmidecode命令及SMBIOS、DMI等：

Linux系统中直接查看BIOS的信息，一般可以使用dmidecode命令

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)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；不过DMTF宣布DMI的生命期在2005年结束了。

使用dmidecode命令时，如果不加任何参数，则打印出所有类型的信息；而加上“-t type_num”或者“-t keywords”可以查看某个类型信息。

dmidecode
dmidecode -t 1
dmidecode -t system
