BIOS

Introduction

The BIOS (Basic Input/Output System) resides in the Flash Memory on your motherboard, serving as the essential link between hardware and the operating system. When the computer starts, the BIOS takes control, performing the POST (Power-On Self Test) to verify the functionality of hardware components. After detecting and configuring hardware parameters, the BIOS hands over control to the operating system. As the central communication channel between hardware and software, the BIOS ensures system stability and peak performance.

In the BIOS setup menu, various configuration options are available. Below are the navigation keys for modifying these settings:

  • Esc: Exit the BIOS Setup.

  • Arrow keys (↑↓←→): Navigate through options.

  • F10: Save changes and exit the setup.

  • Page Up/Page Down or +/-: Modify values for the selected option.

Accessing BIOS

To enter the BIOS Setup:

  1. Power on the system and press the Del key immediately.

  2. If you miss the initial prompt, restart the system by turning it off and back on, or use Ctrl + Alt + Delete for a soft reboot.
