The BIOS is the software that is built into your computer’s motherboard. Each and every time you press your PC’s power button, the BIOS is the first operation to load your operating system and all of the personal settings that make your computer your own, controls everything from the boot order of your drives to preboot security options to whether the Fn key on your keyboard activates a function key or a media control. Inside the BIOS you can change many basic computer settings, like the boot order, system time and date, or enabled hardware components. That’s why the BIOS (basic input/output system) is also known as “Setup”. When troubleshooting, you might need to check your BIOS version to see if an update is available or you may need to check your BIOS version if you plan to update the BIOS.
