You may have heard the term, if but you’re not sure what it means, or you may be completely unfamiliar with what BIOS is, we’ve got everything you need to know about BIOS.

What Is BIOS?

BIOSIf you’re wondering – What does the BIOS stand for? – let us enlighten you. BIOS is an abbreviation standing for Basic Input Output System. In a nutshell, the BIOS represents a collection of non-volatile firmware that allows you to configure individual components of your system unit, as well as your OS loader, and other important settings.

The BIOS is a small chip located on your motherboard, and for good reason, since it’s the motherboard that ensures interaction and proper operation of all computer components.

Many would agree that the appearance of it is somewhat obsolete, with most users not attaching much importance to that. Nonetheless, if you’re looking for more aesthetic, you may opt for the latest models of Asus motherboards featuring modern design.

BIOS Functions

The main function of the BIOS lies in performing hardware initialization during the booting process, as well as providing runtime services for your operating system and various programs.

Using the BIOS, you can:

  • Set the system time;
  • Change the boot order;
  • Change power management settings; and
  • Enable or disable some devices, etc.

BIOSHow To Enter The BIOS

You’ll first need to reboot your computer. Before Windows loads, hold down the Delete or F1 key on the keyboard, depending on the motherboard you’re using. After that, you’ll find yourself in the BIOS.

You can control it using 5 buttons:

  • Arrows help you navigate various sections and select required settings.
  • Enter opens a selected section or selects a specific option.
  • Traditionally, ESC is an exit.

In addition, you can restore default system settings by pressing the “F9” key. By pressing the “F10” key, you can save selected settings.

As for managing BIOS setting on new motherboard models, you can do it with a mouse.

BiosHow to Reset the BIOS

Experienced users sometimes resort to resetting their BIOS to restore factory settings. Resetting the settings is more of a necessary measure taken when the previously made changes had led to critical errors, problems with the entire system, or a devices.

Locate the following jumpers on your motherboard: CCMOS, Clear CMOS, or Clear RTC.

Each manufacturer offers their “recipes” for resetting the settings. Still, keep in mind that resetting the BIOS settings should be performed only when the computer is turned off, as well as other devices connected to it.

After locating the jumper, move it to the other two pins. For example, if the jumper is covering the first and second pins, move it so that it is covering the second and third pins. Make sure to pull the jumper straight up to remove it. After you boot up your PC, you’ll discover it has been reset.

It’s also possible to reset your BIOS by removing the CMOS battery. To do it, unplug your PC from any power sources, open your case, and remove the CMOS battery that’s usually located next to your PCI slots. If you’re unable to locate the battery, make sure to check under expansion cards and cables. If the battery doesn’t remove, which is also possible, don’t use force to pull it out. Instead, opt for the “jumper” option described above

Flashing The BIOS

Oddly enough, the BIOS features its own firmware, which can be updated. Updating the firmware can eliminate some problems with it and its settings. There is no special need to update the firmware, but if you have problems with it and you have specialized knowledge to perform this procedure, you can update the firmware. Read how to update it in the manuals, in which this process is described specifically for your motherboard.

You can download the latest firmware for your motherboard from the official site of its manufacturer. As a rule, flashing the BIOS is done using a special utility stored on your motherboard driver CD/DVD that comes with a motherboard.
