How to Update Your BIOS

The Basic Input Output System, usually referred to as BIOS, is software stored on a small memory chip on the motherboard.

BIOS is sometimes incorrectly referred to as the Basic Integrated Operating System. BIOS instructs the computer on how to perform a number of basic functions such as booting and keyboard control.

BIOS is also used to identify and configure the hardware in a computer such as the hard disc, floppy drive, processor, etc. As with any software, your computer or motherboard manufacturer periodically updates the BIOS to fix bugs, add compatibility with new devices, improve caching functions, and make several other hardware tweaks that can speed up your boot time and fix annoying issues. Follow these steps to update your BIOS without any problems.

1. Identify your Current BIOS Version

Open the Command Prompt (Search for 'cmd' in your Search Window) and type the words "systeminfo" (without the quotation marks) and hit Enter. After a few moments, a screen will appear giving you a report of information about your system and the BIOS version installed. 

1. Find The Most Current BIOS

Although most PC manufacturers don’t actually build the motherboards they use, they do maintain libraries of BIOS updates. So pay a visit to your PC manufacturer’s website to see if there’s a newer version available. Jot down the model number you own and go to the Support or Downloads area of the site. If you’ve built your own PC, go directly to the motherboard manufacturer’s site. You can get the model number of your motherboard in step one, above. In either case, you should also download any readme files or other documentation related to the BIOS update.

Note: Make sure that you Back Up Your Existing BIOS. This won’t necessarily help you recover from a failed BIOS update, but it will give you something to roll back to in the event you encounter any compatibility issues.

2. Find the latest BIOS Version and Read the Manual

After noting the model number of your motherboard which you got after doing the 1st Step, Visit your Motherboard manufacturer's Website to find out if there is a Newer version available. You will find the update details in  the Support or Downloads area of the site. Also take a good look at any documentation that accompanies the new BIOS version. Read the manual that comes along with the your PC or Laptop on visiting the manufacturers website.

3. Update Your BIOS

Make sure that you download the correct update from your verified manufacturer's website.
After downloading the update, Install it. When the program is finished, reboot your machine using your new BIOS. After updating start your system again to find the new update working perfectly.
And if some went wrong during the BIOS update and the PC fails to boot, you should first refer to your user manual for your system’s BIOS recovery procedure. If your computer doesn’t have such a feature, most older motherboards have a jumper setting that you can strap to reset the BIOS to its default values and try booting it again. If you’ve programmed the BIOS with an incorrect version and your computer still won’t boot, you’ll need to restore the BIOS using a bootable USB thumb drive.
