How to update the BIOS of your computers motherboard in 5 steps

One of the most important things you should not mess is updating the BIOS of the computer’s motherboard. Yes, the process is not that complicated, although it is not easy, but there are so many things that you must get right, it might seem overwhelming. We decided to help and share a list of best practices that will help to update the BIOS without problems from his first attempt.
Let’s begin:

NOTE: If this is the first time I have heard of the BIOS or you do not know exactly what it is, read this article: simple questions: What is the BIOS and what it does? .

Step 1: Find the BIOS version that uses your computer’s motherboard

First, you will need to find if there is an update available for the BIOS on the motherboard of the computer. To do that, you need to know the current BIOS version being used by the team. There are many ways to learn the BIOS version and we have shared in this article: 6 Ways to learning BIOS version on your computer.

Step 2. Check for any BIOS updates available

Once you know the BIOS version used by the computer’s motherboard, it’s time to see if new updates are available. To do this you must find the support page of the company that makes the computer (if it is a system of pre-compiled HP, Dell and others) or motherboard (if not a computer brand). The manual you received for your computer or motherboard should tell you what this site is.

Once you have landed on the website of manufacturer support, look for something as drivers or downloads. Because each computer model or motherboard has its own specific BIOS, you have to identify exactly. The manufacturer’s website usually offers more ways to do that. You will probably be able to use a search box, a list of products and models, or application that you can download and run to automatically find the appropriate BIOS version for your computer.

Once you have correctly identified the computer or motherboard, BIOS and look for the section Download, firmware or utilities. On the BIOS update it is possible to find more than one version available. In addition, each version could be available in different formats, depending on the method you choose to update the BIOS. These methods often include BIOS upgrade directly from Windows, updating from DOS or BIOS upgrade the BIOS itself.

If an update for the BIOS is available, download the latest version, taking care to select the file for the method that will be used to upgrade.

Be sure to download the BIOS update for the exact model of your computer or motherboard and not another. If you manage to rewrite the BIOS with a BIOS that is written for other computer model or motherboard, you run the risk of bricking your motherboard.

Step 3. Prepare your computer for the upgrade

Preparation of the team is a very important updating the BIOS step and there are a couple of things you should do:

Read the readme files that are distributed with the BIOS update files that you downloaded. These can give you very important information about the update procedure information and what to do and not do. If possible, try to update the BIOS for the use of a reliable source of electricity. If you are upgrading the BIOS of a laptop or other portable device, make sure your battery is fully charged. If you’re doing it on a desktop computer, use an uninterruptible power supply if you have one. These precautions are necessary because only a small power fluctuation can corrupt the BIOS while it is being updated. That can lead to a computer unusable. If you are upgrading from Windows BIOS it is preferable to clear running any antivirus or security suite, so it does not block anything during the upgrade process.

Step 4. Back up your existing BIOS Version

Most BIOS update programs include an option to backup your current BIOS version. If this feature is available, take advantage of it and back up your existing BIOS version before upgrading. In case something goes wrong with the update, the backup can be a lifesaver.

If the BIOS update program provided by the manufacturer of your computer or motherboard does not provide a backup option, a good free alternative is the Toolkit universal backup BIOS.

Try it and use it to back up your existing BIOS version.

Step 5. Update the BIOS of your computer or motherboard
The steps depend on the method you chose for updating the BIOS.

Step 5.1. Updating the BIOS from Windows

The simplest method is to update the BIOS from Windows. If this is what you choose, you must have one or more files downloaded to your computer. Here you can see an example of what should have when updating a motherboard Asrock. These files must have an executable.

Double click or tap to run the executable. To begin the BIOS update you may need to choose the new BIOS or may be automatically selected. Then look for a button called Update, Flash, Run or something similar and click or tap on it. Once you’ve done that, all you have to do is relax and watch your BIOS being updated.

In most cases, when the process is done, the upgrade program will notify you that a reboot is necessary.

If all went well, the BIOS has been updated. You can now access it and adjust its settings to your liking.

Step 5.2. Updating the BIOS from DOS

If you choose to update the BIOS from DOS, you must create a boot drive (USB stick, CD bios DVD, external hard drive) and copy the file (s) BIOS in it. Then restart the system and boot from this drive. Depending on the instructions shared by the manufacturer of your computer bios motherboard, you will need to execute a specific command. This may simply be the filename of the BIOS or it may be something like the following command:
afudos bios inewbios. rom
Wait for the BIOS upgrade and restart the computer.

Step 5.3. Updating the BIOS BIOS

A third method involves updating the BIOS using the BIOS itself. Some manufacturers include this feature. However, it takes a different name from one manufacturer to another. For example, if you have a motherboard Asrock, its BIOS will have an immediate utility Flash. If you own an ASUS motherboard, its BIOS will have a utility called EZ Flash.

Such utilities usually request that the new BIOS file is saved on a USB drive or external memory. This unit does not have to be bootable and there is no command to be executed in order to start the update process. These utilities automatically detect the presence of the new BIOS file on the drive that you selected and start the BIOS update. When the update is complete, restart your computer and go.


Updating the BIOS is not as difficult as it seems at first, but it does require some attention and care. If you mess up a little detail, you will have a lot of problems to deal with. Also, things like a power failure during the update process can corrupt the BIOS and make your computer unusable. These problems can only be repaired by specialized computer repair shops or the manufacturer of your personal computer.
