If you’re updating the BIOS on a laptop, you’ll want to make sure the battery is fully charged and you’re plugged into the charger.It’ll handle installing the new BIOS and restarting your computer. You’ll need to load the BIOS files you downloaded to an external USB drive and plug it in. When your computer restarts, there should briefly be white text on a black screen (perhaps with a logo) that tells you the key you need to press to get into the BIOS.This will be easy to miss, but the keys are usually F1, F2, F11, Esc, or Delete.The BIOS also runs a Power On Self Test, or POST, which discovers, initialized and catalogs all connected devices, and provides an interface for conjuration.
It also loads the operating system into the RAM from a boot device.
Otherwise you can download CPU-Z and it’ll tell you.
