BIOS

Determining the BIOS version

The BIOS version is usually displayed quickly when a computer is booting, and when you are in the BIOS options screen

You can also get the BIOS version when your operating system is running!

From Windows

Use the msinfo32 command and check the BIOS version line in the system summary screen

From Linux

Use the dmidecode command: dmidecode -s bios-version

$ sudo dmidecode -s bios-version
[sudo] Password for your_login:
1.10.0

Entering the BIOS

Power off the machine, then power it on again and press repeatedly the appropriate key several times while the computer is starting, until you see the BIOS options screen. This should take place before you have to type the Windows bitlocker password, or the Linux (de)crypting password
