如何从Linux命令行本身查看BIOS设置。
如何避免停机查看BIOS设置。
是否可以在不重新引导服务器的情况下查看BIOS设置?
您可以使用biosdecode和dmidecode命令从CLI获取BIOS设置。
biosdecode命令解析BIOS内存并打印有关所有结构的信息。
dmidecode是用于以人类可读格式转储计算机DMI(SMBIOS)表内容的命令行工具。
下表包含系统硬件组件的说明。
它还包括其他有用的信息,例如序列号和BIOS版本。
如何在Linux上的命令行中查看BIOS设置
打开终端应用程序。
您必须以root用户身份登录才能运行命令:
$ sudo -i
或者
$ su
执行以下命令:
# dmidecode | more
输出示例:
# dmidecode 3.0 Getting SMBIOS data from sysfs. SMBIOS 2.7 present. 66 structures occupying 3170 bytes. Table at 0x000E0840.

有关更多信息,请参阅在不打开机箱的情况下从shell获取有关BIOS /服务器硬件的信息(BIOS Decoder)。
另一种选择是运行:
# biosdecode
您也可以使用命令诸如hwinfo。
它用于探测系统中存在的硬件。
它可用于生成系统概述日志,以后可用于支持。
# hwinfo # hwinfo --short # hwinfo --disk # hwinfo --short --block # hwinfo --disk --only /dev/sdb
