We all know that it is necessary to keep our PC in good condition and updated. In relation to this, it is also important to keep the BIOS or UEFI updated. Therefore, in this article you will learn what the BIOS or UEFI, how to update it and why it is important and necessary to do so. Perhaps you do not have much knowledge of this topic, so before continuing we invite you to know what the BIOS is, what it is used for and how it works, in this article.
What is BIOS or UEFI and why is it necessary to update it?
Before entering the matter, it is necessary that you know that both the BIOS and the UEFI are firmwares, that is, a portion of code that is stored in a separate memory located on the motherboard of your PC.
The firmware is responsible for starting, configuring and verifying that the hardware of the computer is in good condition. This includes memory RAM, hard drives, and motherboard or graphics card. Then, select the boot device and proceed to start the operating system, giving it control of the PC.
Taking this into account, the BIOS (Basic Input Output System) or Basic Input and Output System in Spanish, resided on the computer’s motherboard and began to perform its tasks from the moment the PC was started.
It was a chip or integrated circuit that inside stores a series of software routines that put the rest of the motherboard’s hardware into operation.
We talk about BIOS in the past because this firmware was eventually superseded by UEFI. The UEFI (Unified Extensible Firmware Interface) is actually the successor firmware to the BIOS. After so many years it was logical that this was obsolete. Therefore, several tech companies came together to found this new firmware.
So the UEFI basically performs the same but improved BIOS functions and some new ones. For example, it has a much more modern graphical interface, a more secure boot system, a higher boot speed and support for hard drives larger than 2 TB.
It is necessary to update the firmware since it runs the PC board with a processor that could not be installed before and also to solve accounting issues with certain types of hardware with memories or boards.

How to update BIOS or UEFI?
Keeping the above in mind, it is necessary to update the UEFI, however, it should not be done unless it is really necessary since any wrong step could lead the computer to the end of its active life.
Download the firmware from the official website of your device.
Access your BIOS OR UEFI menu. For that you just have to press “Del” several times until the menu appears. There we will see the version of our firmware.
With that information we can go to our provider’s page and check if there is a later version than the one we have and if it is really necessary to update it or not.
After making sure of all the data and verifying that we have to update it, we must access the manufacturer’s website and in the technical support and downloads section we will see if there is an update available.
Once we see that there is an update, we will download it. This file is a ZIP with ROM or firmware ready to install quickly and easily. If the file in the ZIP is an executable then we unzip it and execute it.
Normally, unzipping and running it is enough to update the BIOS or UEFI. It is important that before this you close all the programs that you have open since it could generate conflicts between the programs.
If the file is not executable, you must transfer it to a previously formatted pendrive. Then, you must restart the computer, enter the BIOS or UEFI and with the pendrive inserted you will see the option “Advance”. Then a wizard will allow you to choose the drive where the downloaded file is located. All you have to do is select it, accept the process and download.
And so in these simple steps you can update the Bios, on the other hand if you want to disable the UEFI of the BIOS of your Windows PC, continue reading this link.
