What is a BIOS?

BIOS is the basic input/output system for the computer. It starts the computer’s initial program loading and provides communications among the various hardware devices. This component is like a liaison between hardware and an operating system making sure it can understand internal parts of the computer.


BIOS is a short form for Basic Input/Output System, which acts as a primitive software program that provides a wake-up call for the system, and a channel through which its hardware communicates with one another. This acts as a connection between the hardware and the operating system so that the computer can identify these internal components of the computer.

The role played by BIOS during the booting process:

1. Power-On Self-Test (POST)

After acquiring control, Bi-OS performs post which is a full range of diagnostic checks ensuring there are no hard wear defects, like on the CPU, main memory and external storage, input/output controllers, etc. The purpose of this is to ensure necessary components work properly, before the boot process.

2. Boot Loader Initialization

After the successful completion of POST, BIOS locates and loads the boot loader, which starts the OS. The boot loader is an intermediate between BIOS and the operating system that provides a smooth passage of commands from the hardware initialization process to running software.

3. Operating System Initialization

After that, the boot loader hands over the command to the operating system whereby it loads a few more components such as drivers, and starts initializing required system services. The computer becomes ready to work when the operating system takes control of it.

Key Functions of BIOS: Ensuring Smooth System Operation

BIOS serves a multitude of essential functions that guarantee the smooth operation of the computer system:

1. Hardware Initialization and Configuration

BIOS identifies and adjusts different hardware parts so that they can easily exchange data and act as one unit. It creates a linkage with the processor RAM, hard disk, input-output devices, etc, which are peripherals.

2. System Settings Management

The user interface of the BIOS is mainly text-based and can have some little graphics to enable the configuration of system settings. These settings encompass boot order, memory, power management, and date/time for the operating system.

3. Low-level Hardware Control

Low-level hardware interaction is handled by the BIOS making sure that the system can respond to the user’s input and perform necessary hardware operations. For example, this includes functions like keyboard and mouse input, system fan management, power consumption, and hardware monitoring.

4. Security Features

The BIOS may also comprise security features like password protection that prevent other unauthorized persons from accessing the system. Such attributes may avoid tampering with the settings of a system, including cases of malice that would jeopardize the system’s integrity.

Let us see how to enable graphics card in BIOS:

Enabling the graphics card through the BIOS would let the PC utilize its own GPU for imaging rather than relying upon IGP built into the motherboard. This will enhance your computer’s efficiency in gaming, video editing, and other graphic-intensive tasks.


There are many ways to enable graphics card in BIOS, depending on your computer manufacturer as well as the BIOS version. However, the general process is as follows: 

  1. Restart your computer. When your computer begins to reboot, you should strike a key that allows you to get into the BIOS. The delete key is often used in place of this key.
  2. Find the BIOS settings of your graphic card. These settings will be located within different locations depending on the BIOS that you use, but most likely under the advanced or peripherals menu section.
  3. Enable the graphics card. The option might be labeled PEG, Primary Graphics Adapter, or PCI Express Graphics.
  4. Finally, save any changes and exit BIOS. Reboot your PC, and now, you are running on the dedicated graphics card.

In case you do not know how to enable the graphics card in BIOS on start-up, check your computer’s manual or call its manufacturer.
