How to update bios asus step by step

Asus is one of the leading motherboard manufacturers in the world, and it deserves a single article dedicated to how to update Asus BIOS. There are many users who use boards of this brand to mount their computers, and sometimes they do not find the concrete and effective way to update their BIOS safely.

As we always think of the best for our readers, we have decided to do a new step by step that tells the process in detail of how to update our Asus BIOS. You will not need to install strange programs or visit a lot of Russian forums to do the procedure, since that's what we are there for.

Do you know what is the utility of the BIOS?

What would be the point of updating your BIOS if you still don't know exactly what its existence is for? And the truth is that we only remember the BIOS when our PC has a problem and even formatting it we have not solved it. Then at the end we will leave a couple of useful articles about the problems that our processor or motherboard can give.

Let's go to what interests us, the BIOS or in Spanish, " Basic Input and Output System " and basically a chip provided with a permanent storage flash memory that is natively installed on our motherboard. A computer wouldn't be able to boot if it weren't for this little chip with a program inside it.

The BIOS is responsible for initializing all the devices that are connected to the motherboard and the PC, for example, the processor, RAM, hard drives, mouse and keyboard, etc. But it is that in addition to initializing them, the BIOS performs a check on all these components for errors or incompatible elements, and it is for this reason that sometimes we get a sequence of beeps when booting a newly mounted or very old PC. It is there when our heart speeds up and the burdens begin, because without a doubt, something is wrong.

The evolution to the UEFI

Currently the BIOS system of modern motherboards has been updated a lot since the first BIOS Phoenix or American Megatrends appeared in their day with their beautiful blue color in conjunction with the Windows Screen of Death. The case is that the BIOSes are currently called UEFI (Extensible Firmware Interface), and it is a profound evolution of the traditional system, adding new, much more advanced functionalities and a way of user interaction that is more similar to a supported operating system. for mouse and keyboard.

And something that this update has brought with it, is the presence of tools within the BIOS itself, such as a more friendly overclocking, the possibility of making screenshots, and what we are dealing with today, a tool to be able to update the BIOS quickly and secure with just a few clicks.

How updating a BIOS benefits us

Well, the fundamental benefit to obtain by updating a BIOS is to always have support for the latest hardware available on the market. We already know that manufacturers release new models almost daily, for example the amount of daily hardware news that we usually get. The fact is that in some cases this update is necessary to support critical components like a new CPU or RAM.

But, in addition, it is a much more complex firmware than that of an old BIOS, so there are usually small bugs in this firmware that make the system unstable or problems with certain hardware are detected (bad luck for anyone who I touched). For all this, it is very worthwhile to gradually inspect the manufacturer's page to check for updates.

Let's take an example: AMD will shortly be releasing our Ryzen 3000 processors with a new 7nm architecture and major changes in processor structure. It is announced that current AM4 socket boards will support both old and new processors, but as long as they have their BIOS updated. Otherwise, surely when we put this new CPU on a board from two years ago, it will either not work or we will have a rather unstable system. We hope we have convinced you of the usefulness of the update.

In most manufacturers, if not all, we will have two ways to update the motherboard BIOS:

• From within the BIOS: We have already said that the new UEFI BIOS have a tool installed within them that allows us to update it safely and easily just by having a firmware image on a flash drive. From the operating system: in the same way, all manufacturers have applications to manage BIOS and basic hardware functionalities from our OS. One of these features is updating the BIOS. We don't consider it as safe as the first method, but it can be more comfortable.

Update Asus BIOS from within the BIOS

So let's go to the practical part after brainwashing so you can update your BIOS. We will start with the first method discussed, since in our opinion it is the safest and with which we ensure that we have the latest version of the BIOS on our computer.

Firmware download

To start, we will have to know the model of our motherboard well, since the manufacturer has different firmwares depending on the model of the motherboard we have, and we do not want to make a mistake, right?

Visit our article to know how to find out the model of your motherboard

With the information obtained, we will go directly to the manufacturer's website to use its search engine and locate our specific motherboard. Of course, we can also use the browser search engine, in short, all roads reach Rome if we know how to do it right.

Well, within the tab of our Asus board, we will have a small menu to go to the characteristics, description and what we are interested in " support ". Well, once in the support section, it's time to go to the subsection of " Drivers and utilities ". As if that were not enough, we will still have to go to another section within this where the Firmware list of our BIOS will be found, as always, ordered by dates.

Prepare for installation

Once we have the file that we are interested in downloaded, the next thing we have to do is unzip it and copy all the files that it had on a USB flash drive. In principle, it is not strictly necessary, since the BIOS detects all the storage units, but if we want to have it well located, we recommend doing this.

If more than one file comes, the one that really interests us is the one with a.CAP extension. We will not need to do more, just restart our computer and access the BIOS in the normal way in which we do it. Asus uses the "Delete" key to enter the BIOS, or in its case the "F2" key, so as soon as the PC starts up again, we will press repeatedly and as if there was no tomorrow this key to enter inside.

Update process

Well, it's time to update, finally. Inside the BIOS and located on the main screen, we will have to look for the Asus EZ Flash tool, so, if it is not on the main screen, we will have to go to the advanced options section " Advanced Mode"

Here, in advanced mode, we will go to the end of the list of options where " Tool " is located. Inside, we will already have the application that interests us. We just have to click on it to run it.

In the first window that appears, we can choose whether to update the BIOS from a storage device, which is our case, or through the Internet.

Well, once the first option is chosen, the tool will detect all the disks in the system, including the flash drive where we have the file. On the right it will appear, so we must select it by double-clicking for the update process to take place.

During the process in which we see a bar below, we must not restart or turn off our PC, since we could run out of BIOS, main, although good, the most current boards have double BIOS.

Update Asus BIOS from Windows

Now we will quickly see how the same process would be done from the Windows 10 operating system.

To start, we would again have to go to the page related to our motherboard to download the software in question. So again we will enter " Support " (the one on the board, not the generic one), then " Drivers and Utilities " and " Drivers & Tools ".

Next we are going to look in the software list that shows us one of these two utilities:

• ASUS EZ Installer: It will be the tool that executes the BIOS update directly. AI Suite III: This software is the generic one to control all aspects of our motherboard, fans, USB, sound and also the BIOS update, since it implements EZ Update.

We are going to download the latter to get more out of the plate. It is possible that you already have it installed, for those who do not, it will be as simple as downloading it, executing it, and installing it as normal and current software.

Well now we are going to run the program and go to the options panel, located on the left side. Here we will choose " Asus EZ Update " and then click on " Search now " so that the program searches directly on the Internet for the most current version of the BIOS firmware, and in case we have it out of date, it will proceed to install it.

We just have to click on " connect " to perform the search. In our case. We already have the latest updated version, so it just tells us that "it is not necessary to update the environment".

Conclusion and interesting articles

Well there we have the procedure to update the BIOS of an Asus board. This process is very similar to that of other manufacturers such as Gigabyte or MSI, since, in short, a UEFI BIOS from the manufacturer, will have practically the same advantages.

Having the updated BIOS will be important to obtain maximum compatibility with all types of new generation hardware. All manufacturers are always one step ahead of the new models to come out, and provide all users with firmware updated prior to the official release, an example is the BIOS updates for the next Ryzen 3000.
