是否可以从正在运行的 Ubuntu 实例检查我的计算机的 BIOS 版本?
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
