答案1

您可以从计算机的 DMI（桌面管理接口）AKA SMBIOS（系统管理 BIOS）表中获取信息，使用转储它dmidecode，并获取类型 0（BIOS）的值：

sudo dmidecode -t 0
sudo dmidecode -t 0 | grep 'Version:'

sudo dmidecode -t bios
sudo dmidecode -t bios | grep 'Version:'

查看man dmidecode。

例子：

% sudo dmidecode -t 0
# dmidecode 2.12
# SMBIOS entry point at 0x000f04c0
SMBIOS 2.7 present.

Handle 0x0000, DMI type 0, 24 bytes

您还可以检查输出lshw以获取有关 BIOS 的一些基本信息：

$ sudo lshw | grep -A8 '*-firmware'
     *-firmware
