Computers are now coming with UEFI firmware instead of the traditional BIOS, but the same is true for UEFI – it’s low-level system software with a similar role.
Unlike your operating system (which is stored on your hard drive), your computer’s BIOS is stored on a chip on your motherboard.
You will often want to flash your computer from DOS (yes, DOS – you may have to create a bootable USB drive with DOS on it and restart into that environment), as problems could occur when flashing from Windows.
You should only update your BIOS if the new version contains an improvement you need. 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.Updating your operating system and software is important.On the other hand, we have previously covered why you shouldn’t generally update your hardware drivers, although gamers will definitely want to update their graphics drivers. BIOS updates will not make your computer faster, they generally won’t add new features you need, and they may even cause additional problems.BIOS flashing tools usually try to detect whether the BIOS fits your hardware, but if the tool attempts to flash the BIOS anyway, your computer could become unbootable.
If your computer loses power while flashing the BIOS, your computer could become “bricked” and unable to boot.If your computer is working properly, you probably shouldn’t update your BIOS.You likely won’t see the difference between the new BIOS version and the old one.However, most computers made in the past four years boot Windows 10 too quickly to listen for a key press at startup. You can get there by clicking the gear icon on the Start menu. To access your BIOS on a Windows 10 PC, you must follow these steps. Windows 10 gives you a lot of options you can configure directly within the operating system, but on every computer, there are some settings you can only change in the BIOS (basic input / output system).
