You don’t need to keep your eyes laid all the time on your system’s BIOS version. The term actually comes to the light when a BIOS update is released and the system starts asking for this update.

Downloading a BIOS file (latest)

Go to your system (motherboard) manufacturer’s official website and find the model whose BIOS update you want to do. Go to the Download/Support page of your model (on that site) and there you’ll see all the BIOS versions with their details like the release dates, bug fixes and other new features.
Check the details of your current BIOS and compare it with the available BIOS version on the site. This would help you in choosing and downloading a correct BIOS file.

Note: Choose the version next to your existing version or simply update to the latest version available on that page.

Extract the contents of the .zip file (Downloaded BIOS file). It contains a BIOS file and a readme.txt file. You can see this .txt file for the instructions which will guide you towards updating your BIOS.

Updating the BIOS

Before moving to the update, you need to copy BIOS files to a CD or a bootable USB drive. The readme.txt file would tell you the BIOS flashing tool your motherboard supports. You’ll need to choose this tool only out of a no. of flashing tools for different motherboards.

Method 1:

BIOS Flashing is either directly displayed in the BIOS (thanks to some manufacturers), or requires pressing a special key while the system is booting up. Just keep in mind copying the BIOS file, you downloaded, to the USB drive and reboot the system. Press the right key at the right time to show up the BIOS screen (search in your PC’s manual, is F2/Delete button usually).
Choose the Bios updating option, select the BIOS file from the USB drive and that’s it. Your Bios will now be updated to a new version.

Method 2: From a DOS USB Drive

For DOS based BIOS flashing tool utility, simply copy the BIOS file and the supported flashing tool to a live DOS USB drive (create it). Reboot the system and then boot from the USB drive. Run the command flash.bat BIOS3245.bin and you’d see the new version of BIOS. Follow the instructions step by step and this would ultimately update your BIOS. (The file with .bat or .exe file extension in the downloaded BIOS file is the DOS based flashing tool).

Why you shouldn’t use Windows flashing tools to update your BIOS?

There are certain Windows flashing tools which can be easily run on the desktop. These flash the BIOS and then proceed to the system reboot. This is a risky process as your system can freeze or be bricked due to the interference of processes running in the background. This can cause errors while writing the BIOS which would bring more problems to the system instead of doing anything good. So to make sure that your BIOS is not corrupt, don’t update it using these flashing tools.
BIOS-based or the DOS-based flashing tools are safer in comparison.

What next to running the BIOS flashing Utility?

Reboot your system once the BIOS update is complete and you’ll feel the performance of the new BIOS version. You can cross check it by checking your system’s BIOS version back again (see the methods to check the BIOS version discussed above). It would be different.
