All modern PCs, laptops included, have a special Startup or Setup program. This program is not a part of your computer’s operating system (Windows). Instead, it’s built in to the computer’s circuitry, or chipset, and it might also be referred to as the BIOS Setup program. What the setup program does is configure your laptop’s. BIOS stands for basic input/output system. When you power your computer on, your BIOS takes control, starting the power-on self test (POST) and passing control over to the boot loader, which boots your computer’s operating system. The BIOS is low-level system software that should “just work” without getting in your way.
