CentOS 7 查看 BIOS 信息
BIOS (Basic Input/Output System) 是计算机开启时运行的固件,它负责初始化计算机的硬件设备,并启动操作系统。在 CentOS 7 中,可以通过不同的方式来查看 BIOS 信息,本文将介绍三种方法。
方法一:使用 dmidecode 命令
dmidecode
是一个能够从 BIOS 中读取信息的工具。在 CentOS 7 中,可以使用以下命令安装 dmidecode
:
sudo yum install dmidecode -y
安装完成后,可以使用以下命令查看 BIOS 信息:
sudo dmidecode -t bios
命令执行输出的结果类似于以下内容:
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 2.8 present.
Handle 0x0000, DMI type 0, 24 bytes

方法二:使用 lspci 命令
lspci
是一个用于显示所有 PCI 总线相关信息的命令。在 CentOS 7 中,可以使用以下命令安装 lspci
:
sudo yum install pciutils -y
安装完成后,可以使用以下命令查看 BIOS 信息:
sudo lspci -vvv | grep -i "vendor\|product" --color=auto
命令执行输出的结果类似于以下内容:
00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09)
00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09)
00:14.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller (rev 04)
00:16.0 Communication controller: Intel Corporation 7 Series/C216 Chipset Family MEI Controller #1 (rev 04)
...
方法三:查看 /sys/firmware/dmi/tables/ 目录
BIOS 信息存储在 /sys/firmware/dmi/tables/
目录下的文件中。可以使用以下命令查看 BIOS 信息:
sudo cat /sys/firmware/dmi/tables/smbios_entry_point
命令执行输出的结果包含 BIOS 的详细信息。
通过这三种方法,我们可以方便地在 CentOS 7 中获取到 BIOS 的信息。
