Linux系统如何使用命令查看BIOS信息呢,这多多少少都会困扰到用户。

其它,Linux系统查看主机BIOS信息是非常方便的,使用”dmidecode”命令就可以了。这个工具可以查看主机BIOS数据,在执行时需要以root权限登录。

在命令行输入如下命令:

// run as root user ##
# dmidecode | less
// or use sudo ##
$ sudo dmidecode | less

典型输出内容如下:

# dmidecode 3.1
Getting SMBIOS data from sysfs.
SMBIOS 2.4 present.
10 structures occupying 300 bytes.

当然,如果觉得内容过多不容易区分的话,可以使用如下命令显示特定内容:

# dmidecode -s system-manufacturer   //制造商
# dmidecode -s system-product-name   //制造商名
# dmidecode -s bios-release-date     //制造日期
# dmidecode -s bios-version          //BIOS版本

可以看到,Linux系统也可方便的使用命令行工具显示BIOS的详细信息。
