Jul. 26, 2023 / Updated by Eloise to Windows Driver Solutions

BIOS stands for Basic Input/Output System, and it is a software program that controls the startup, communication, and loading of the operating system on a computer. The BIOS is like the brain of your computer. It tells your computer what to do when you turn it on, how to talk to the different parts inside it, and how to load the system that you use. The BIOS driver is a part of the BIOS that helps it communicate with the parts inside your computer, such as the processor, memory, hard drive, keyboard, mouse, etc. The BIOS driver is saved in a special chip on the motherboard of your computer, and it can be changed to fix problems, work better with new parts, or add new features. This guide will walk you through how the BIOS driver functions and how to update it.

1. What are BIOS drivers?

The BIOS driver is responsible for initializing and testing the hardware devices, setting up the system configuration, and loading the boot loader or operating system. BIOS driver also provides a low-level interface for the operating system to access the hardware devices. It works as follows:

• When you turn on your computer, the BIOS driver performs a power-on self-test (POST) to check the hardware components and verify their functionality.

• The BIOS driver then reads the system settings from a configuration file stored in the CMOS memory, which is a small battery-powered chip on the motherboard. The system settings include the date and time, boot order, security options, etc.

• The BIOS driver locates and loads the boot loader or operating system from a specified device, such as a hard disk drive, a CD-ROM drive, a USB flash drive, etc. The boot loader or operating system then takes over the control of the computer.
