Linux系統如何使用命令查看BIOS信息呢，這多多少少都會困擾到用戶。

其它，Linux系統查看主機BIOS信息是非常方便的，使用”dmidecode”命令就可以了。這個工具可以查看主機BIOS數據，在執行時需要以root權限登錄。

在命令行輸入如下命令：

// run as root user ##

# dmidecode | less

// or use sudo ##

$ sudo dmidecode | less

典型輸出內容如下：

# dmidecode 3.1

Getting SMBIOS data from sysfs.

SMBIOS 2.4 present.

當然，如果覺得內容過多不容易區分的話，可以使用如下命令顯示特定內容：

# 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系統也可方便的使用命令行工具顯示BIOS的詳細信息。
