如何知道我的 BIOS 版本的发布日期？

使用简单的单个命令直接从终端仿真器检查 BIOS 版本的发布日期非常容易。那么如何做到这一点？

答案1

轻松使用命令 dmidecode。

如果还没有安装，请先安装：

sudo apt-get install dmidecode

现在可以轻松运行以下命令来检查 BIOS 的发布日期：

sudo dmidecode --string bios-release-date

输出将如下所示（我的输出）：

07/23/2012

答案2

dmidecode确实是最简单的方法，但应谨慎使用。正如结尾处提到的man dmidecode：

BUGS
   More often than not, information contained in the DMI tables is inaccu‐
   rate, incomplete or simply wrong.

因此，作者自己警告用户返回的信息可能是垃圾。

另一个可用于获取有关 BIOS 的信息（但不是发布日期）的程序是 ，biosdecode它曾经是 BIOS 的一部分dmidecode，但现在已与 BIOS 分离。示例输出：

# biosdecode 2.12
