Your computer
's BIOS, or basic input/output system, is stored on a chip in the motherboard and is designed to run when your computer is powered on. BIOS identifies and tests your system devices (your computer's hardware) and allows the computer's operating system to interface with this hardware. Identifying your BIOS in Ubuntu requires booting on your computer and entering some information in the command line.
Instructions
1. Turn on your computer and enter setup. This usually requires pushing a key or combination of keys before your computer fully loads the operating system (see resources for a website that gives these key combinations by computer manufacturer).
2. At the command line that appears, enter this command exactly:
sudo dmidecode -s bios-version
This will check your current BIOS version.
3. Enter in the following command to get information about the release date of your current BIOS version:
sudo dmidecode -s bios-release-date
4. Exit setup when you are done checking your BIOS version.
