What is BIOS and why do we need it? BIOS is basically a low-level firmware embedded on a non-volatile ROM chip used to perform hardware initialization during the booting process. While modern machines have upgraded to a more advanced visual version called UAFI, the fundamental job remains exactly the same. Your operating system is completely useless without this code running first. When you press the power button, your computer's processor actually has no idea that a keyboard, monitor, or hard drive even exist. That's why BIOS wakes up instantly and runs a diagnostic routine called the Power On Self Test. It systematically to check your RAM, verify your graphics card, and test your processor. If a critical component is broken or missing, the BIOS stops the boot completely and outputs a specific sequence of audio beeps to tell you exactly what failed. But its main responsibility is the bootloader handoff. Once the hardware is verified safe, the BIOS searches your system storage devices based on a preset boot priority list. It looks for a tiny piece of code called the bootloader, activates it, and hands over total operational control of the hardware to Windows, Mac OS, chip, you can access its settings menu before the computer boots.
