The BIOS (Basic Input-Output System) is the software component of the computer that provides a series of functions for accessing hardware and peripherals by the operating system and other programs installed on the computer itself. The BIOS is located in a chip on the motherboard.
Configuring the BIOS is an important operation for those who want to learn how to use their computer to the fullest. Keep in mind that each motherboard uses different BIOSes.
So the appearance and entries on it may vary a little from computer to computer.
But, all in all, the sense of the BIOS settings that I am going to describe below. You can be easily found on almost all the BIOS present in circulation.
Which setting can be configured via the bios screen?
My first tip is to restart your computer with every BIOS change you make to make sure your system is working properly.
If, on the other hand, you make a lot of changes before rebooting and your system doesn’t load properly, you won’t be able to figure out which change caused the problem.
The second tip is to always read the advice on the right side of the BIOS screen. Each time you select an item or option in the BIOS on the right, explanations about it will be provided.
Be aware that incorrectly changing the BIOS settings could make your system unstable. So, proceed very carefully and cautiously.
However, if anything abnormal should happen, you can always do a BIOS reset. This will return the BIOS settings to their default values.
You can reset the BIOS by moving some jumpers on the motherboard. But if you follow my guide step by step, you shouldn’t encounter any problems.
Ready? So, let’s see together how to configure the BIOS.
Enter the BIOS
The process of entering the BIOS may vary depending on the computer you use.
First, to enter the BIOS you have to turn on (or restart, if it was already on) the computer and, while the very first PC start-up screen is shown (the one with the manufacturer’s logo, usually), repeatedly press one of the following keyboard keys: F10, F1, F2 or Del (or DEL).
This key changes from manufacturer to manufacturer, in some cases it is written on the screen but, if not, I suggest you try one at a time to find out which is the one on your motherboard.
You should find an indication on which key to press right on this screen (eg Press F10 to enter setup ).
Set the main BIOS options
Once you enter the BIOS control panel, you will find yourself on the main screen which contains the basic information about your PC and its components (such as processor, RAM, BIOS version and BIOS language) and the options to change the time and date system.
To change them, you must use the keys indicated at the bottom of the BIOS screen.
Further down you will find the settings of Primary Master, Primary Slave, Secondary Master and Secondary Slave.
They are the options related to the hard disks and optical drives on your computer.
In the Primary Master item, there must be the abbreviation of your main hard disk (or SSD), where the operating system is installed.
If you do not have other disks, to speed up the startup of the computer you must avoid that the BIOS checks for the presence of new peripherals connected to the motherboard at each power-on. Set the values just indicated to NONE and not to AUTO.
In fact, they leave the settings on AUTO where there are no devices connected, the computer will search for the presence of a device on that specific port at each start.
On newer motherboards, these options are no longer present as the system optimizes itself.
Configure the BIOS security options
In the Security tab, you will find the options to protect the BIOS and the peripherals on the computer. There you can add an administration password, which will be requested every time someone tries to access the BIOS.
In addition, you can set up a power-on password, which you must enter every time the computer is turned on.
In many BIOSes, there is a panel to monitor the hardware, from here you can monitor the temperature of the CPU and other components of the computer.
