BIOS Introduction
BIOS (Basic Input/Output System) is the motherboard firmware that runs first when the board powers on. It wakes hardware, performs self-tests, and then boots the operating system. In other words, BIOS acts as a “bridge” between hardware and the OS.
BIOS Overview
- Arrow keys: Move between menu items
- Enter: Open or confirm the current option

Knowing these shortcuts makes it easier to navigate through the BIOS pages.
