Most modern computer users have no idea what a BIOS is, why it is needed, do not understand the principle of its operation, do not know how to open it. But every self-respecting user is simply obliged to know what it is.
What is BIOS
So, first, let's find out what BIOS is and what it is for.
BIOS (BIOS) is a program that is written on a special chip, this chip is located directly on the motherboard. There are a huge number of BIOS varieties, but the principle is the same for everyone.
There is a BIOS in every computer, without it the computer simply will not be able to work, tk. in the BIOS, the basic parameters are set, it tells the computer: where to boot from, which systems to use at a certain stage of loading, at what speed to rotate the coolers at a given stage of work. We will not consider all the duties of BIOS, because this list can be continued for a very long time. Also in the BIOS, the basic settings of the components installed in the computer are set. Next, let's figure out why you need to sometimes go into BIOS.
Why go to BIOS
There are a great many reasons why you need to enter BIOS. For example, you bought a new computer that does not have an operating system installed. Next, the user is faced with the task of installing the OS. As you know, the main media from which the operating system is installed are flash drives and DVDs. In order to start the OS installation process, you just need to boot from the selected drive. For this, you need to go to BIOS and select the required device in the download settings.
How to enter BIOS
So, you are faced with the task of entering the BIOS to perform any actions. To do this, you must turn on the computer or, if it is turned on, restart it. When the start window appears, as a rule, there is an inscription “Press DEL to Enter Setup” at the bottom left. If you press the DEL key at this stage of the computer boot, you will enter the BIOS.
The principle of entering the BIOS on all computers is the same, but the key used to enter may differ. Below is a table showing how to enter BIOS on motherboards and laptops from various manufacturers.
