How to properly configure BIOS on a computer

How to configure BIOS on a computer? BIOS The Basic Input / Output System is responsible for the initial boot of the device and initialization of the equipment on a personal computer or laptop.

Today BIOS has a lot of versions and boot options. But, what is it and why, and most importantly, few computer users know how to configure it.
First of all, we will figure out what it contains in itself and what can be done about it. And so, usually the BIOS consists of several parts. Information, Advanced, Main, Power Security, Boot, Exit.

Now in order.
In the Information, or Main section, you will find information about your PC, namely: data and characteristics about the process (frequency, number of cores, etc.), RAM (volume, frequency), hard disk (o ‘volume and technical data ), (integrated, discrete, size).

How to properly configure BIOS on a computer

In Advanced, you can make changes to the configuration of the device as a whole or of individual components.

You can overclock the processor,, RAM frequency (remember, if you do it wrong it will lead to the failure of the device, if you do not have the necessary experience and knowledge it is better not to do this)

Boot is important when we need to choose from which particular device our system will boot and configure their order (optical drive, USB, HDD, etc.)

This is necessary when installing the operating system, or when diagnosing software (the same OS).

Remember that all the changes you make are at your own risk and they can dramatically affect the operation of your computer.

Almost all motherboards have a speaker (squeaker), and when you turn on the computer and hear a one-time squeak, this BIOS sends a signal to the speaker so that it will beep 1 time. The BIOS is needed in fact for the survey of equipment, for the correct transfer to the “next step (I will explain later).” The BIOS has a clock, thanks to them in your computer in a de-energized state. time does not go astray. The BIOS also includes a minimum package of parameters for the motherboard and devices on it, but let’s talk about everything in order.
BIOS setup

What are bios

BIOSes are different, looking at the picture above, you can understand that outwardly they can be very different from each other. But, the main feature of each bios is that they are all similar. Therefore, if you understand one bios, then sorting out the second one will not be difficult for you. Further in the article I want to open each tab and talk about all the functions so that I can understand how bios can be configured.

How to set up bios. Main

The tab “Main” contains information about the current time, date and about the main devices on the board.
System time. the current time in the format “Hours: minutes: seconds” (it can be configured);
System Date. the current date in the format “Day of the week day / month / year” (it can be configured);
BIOS Version. the current version of your BIOS, on the developer’s site you can download the BIOS update and install them, read the article on how to update the BIOS;
Processor Type. information about the processor that is currently installed in your motherboard;
Processor Speed ​​- processor clock speed, measured in megahertz (MHz) or in gigahertz (GHz);
Microcode Update. stability update version for the processor microcode;
Cache Size. processor cache size, measured in KB or MB;
Total memory. the total amount of RAM (RAM), which is installed in the motherboard;
DDR3_A1-A2 / B1-B2. slots for installing RAM, contain information about the type of RAM (ddr. ddr4), the frequency of each bar and the amount of internal memory, if “None”. then the slot on the motherboard is empty.

How to set up BIOS. Advanced

The “Advanced” tab contains information on the main parameters of the system. On many Advanced systems are different, so do not be surprised if in this menu you see other options, as I said. the principle is similar.
JumperFree Configuration. setting the voltage and frequency of the processor, memory, etc.
CPU Configuration. setting the parameters of the central processor, or viewing its current parameters (cache, frequency, multiplier, etc.);

Chipset. chipset setup (south / north bridges);
Onboard Devices Configuration. setting up on-board devices, such as a network (LAN);
PCIPnP. settings for Plug and play devices, as well as PCI / VGA (palettes);
USB Configuration. USB port settings, you can change the port speed settings, disable / enable ports;

An interesting fact: In Advanced, most often there is a menu for overclocking the processor. If anything, here’s a little article about overclocking, all of a sudden anyone is interested.

BIOS Setup. Power

The Power tab contains settings and information that relates to the power of the computer.
Suspend Mode. selection of the operating mode of the motherboard in the economy. mode (depends on the PSU and the motherboard itself);
ACPI 2.0 Support. enables or disables the power management interface version 2.0;
ACPI APIC support. enables or disables the advanced interrupt controller;
APM Configuration. allows you to turn on and off the power supply to the keyboard / mouse PS / 2, PCI / PCIE, etc.
Hardware Monitor. contains information about the temperature of the processor, the speed of rotation of the coolers and the incoming voltage;

An interesting fact: in some versions of the BIOS. in the Power menu, the rotation speed of coolers can be manually adjusted.

BIOS Setup. Boot

The Boot tab is probably one of the most interesting tabs. In it, you can configure the boot order of the OS from different media.
Boot Device Priority. allows you to build the boot order. If you put cd-rom in the first place, then before starting the usual Windows boot from the hard drive, the system will first check the CD-ROM, and if the drive does not have a disk (or there are no suitable data on the disk), the system will go to the second point and start loading Windows on your hard drive;
Hard Disk Drives. option to select the 1st hard drive. If your computer has several hard drives, then some bios can only perceive 1 in the boot queue. Sometimes, to install Windows from a USB flash drive, you need to select your USB flash drive in this menu, and only after that it will appear in the Boot Device Priority menu;
Boot Settings Configuration. adjusting secondary boot parameters (Num power, Quick boot, logo, etc.);
Security. allows you to set passwords for editing BIOS parameters;

BIOS tab Tools

The “Tools” tab usually contains a utility for updating the BIOS. Read more. read our article how to update the BIOS. In a nutshell, I want to say that you need a flash drive and firmware file, said from the official website of the manufacturer of the motherboard (in this case, Asus).

How to set up bios. Exit

The Exit tab contains the final step in BIOS setup:
Exit Save Changes. Exit and save changes;
Exit Discard Changes. Quit without saving changes;
Discard Changes. discard changes;
Load Setup Defaults. Apply all the “Default” parameters;
