In this instruction, I will proceed from the fact that you know why you need an update, and I will describe how to update BIOS in steps that should be performed regardless of which motherboard is installed on the computer.
In the event that you do not pursue a specific goal, updating the BIOS, and the system does not show any problems that could be related to its work, I would recommend leaving everything as it is. When updating, there is always a risk that a failure will occur, the consequences of which are much more difficult to fix than reinstalling Windows.
Is an update required for my motherboard?
The first thing to find out before proceeding is to revise your motherboard and the current version of BIOS. This is not difficult to do.
In order to find out the revision, you can look at the motherboard itself, there you will find the inscription rev. 1.0, rev. 2.0 or similar. Another option: if you still have a box or documentation for the motherboard, there may also be revision information.
In order to find out the current BIOS version, you can press the Windows + R keys and enter msinfo32 in the Run window, and then see the version in the corresponding paragraph. Three more ways to find out the BIOS version .
Armed with this knowledge, you should go to the official website of the motherboard manufacturer, find the board of your revision and see if there are BIOS updates for it. You can usually see this in the “Downloads” or “Support” section, which opens when you select a specific product: as a rule, everything is quite easy to find.
Note : if you bought an already assembled computer of any major brand, for example, Dell, HP, Acer, Lenovo and the like, you should go to the website of the computer manufacturer, not the motherboard, select your PC model there, and then in the section downloads or support to see if BIOS updates are available.
Various ways BIOS can be updated
Depending on who the manufacturer is and what model of the motherboard on your computer, BIOS update methods may vary. Here are the most common options:
- Update using the manufacturer's proprietary utility in the Windows environment. The usual way for laptops and for a large number of PC motherboards is Asus, Gigabyte, MSI. For the average user, this method, in my opinion, is preferable, since such utilities check whether you downloaded the correct update file or even download it yourself from the manufacturer’s website. When updating BIOS on Windows, close all programs that you can close.
- Update in DOS. When using this option, modern computers usually create a bootable USB flash drive (previously a diskette) with DOS and the BIOS itself, as well as possibly an additional utility for updating in this environment. Also, the update may contain a separate Autoexec.bat or Update.bat file to start the process in DOS.
- Updating BIOS in BIOS itself - many modern motherboards support this option, and if you are absolutely sure that you have downloaded the correct version, this method will be preferable. In this case, you go into the BIOS, open the necessary utility inside it (EZ Flash, Q-Flash Utility, etc.), and specify the device (usually a USB flash drive) from which you want to update.
For many motherboards, you can use any of these methods, for example, for mine.
How exactly to update BIOS
Depending on what kind of motherboard you have, BIOS updates can be performed in different ways. In all cases, I highly recommend reading the manufacturer's instructions, although they are often presented only in English: if you are too lazy and miss any nuances, there is a chance that during the update there will be failures that will not be easy to fix. For example, the manufacturer Gigabyte recommends disabling Hyper Threading during the procedure for some of its boards - without reading the instructions, you will not know about it.
Instructions and programs for updating BIOS manufacturers:
- Gigabyte - http://www.gigabyte.com/webpage/20/HowToReflashBIOS.html . The page presents all three of the above methods, where you can also download the program for updating BIOS on Windows, which itself will determine the desired version and download it from the Internet.
- MSI - to update the BIOS on MSI motherboards, you can use the MSI Live Update program, which can also determine the required version and download the update. Instructions and the program can be found in the support section for your product at http://www.msi.com
- ASUS - for new Asus motherboards it is convenient to use the USB BIOS Flashback utility, which you can download in the "Downloads" - "BIOS Utilities" section at http://www.asus.com/en/ . Older motherboards use Asus Update Utility for Windows. There are options to update BIOS in DOS.
One point that is present in almost any manufacturer’s instructions: after the update, it is recommended to reset the BIOS to the default settings (Load BIOS Defaults), then reconfigure everything as needed (if necessary).
The most important thing that I want to draw your attention to: be sure to look at the official instructions, I don’t specifically describe the whole process for different boards, because if I miss one moment or you will have a special motherboard and everything will go wrong.
