By the end, you’ll be able to update your BIOS with confidence and hopefully solve those pesky computer problems.

What Is BIOS?

BIOS (Basic Input/Output System) is firmware embedded in a chip on the motherboard of your computer. It controls the boot process, performing hardware checks and initializing components like the CPU, RAM, and storage devices before the operating system starts. Without a properly functioning BIOS, the computer can’t communicate with its hardware, meaning it won’t boot or recognize key devices. BIOS also determines the boot order, which defines whether the system should boot from the hard drive, USB drive, or CD/DVD first.

When you turn on your computer, BIOS runs a Power-On Self-Test (POST) to ensure all hardware components are working correctly. It then loads the bootloader, which initiates the operating system. The configuration for BIOS settings can usually be accessed by pressing a specific key (like F2 or DEL) during startup. These settings let users manage important configurations like system time, boot order, and hardware monitoring.

More recent computers have shifted toward UEFI (Unified Extensible Firmware Interface), a modern replacement for BIOS that offers enhanced functionality. While BIOS is limited in terms of storage and hardware support, UEFI allows for larger storage drives, faster boot times, and a graphical interface for easier navigation. UEFI also supports secure boot, which helps prevent malware from infecting the boot process.

The transition from BIOS to UEFI gives systems more flexibility and improved performance, particularly in modern computing environments.
