If you can access BIOS on your PC, you can do various things such as change hard drive settings, create a password for BIOS to make your computer more secure, change the boot order, and more. Otherwise, an error message such as the BSOD (blue screen of death) or several others will be displayed. Once everything has been certified OK during startup, your computer will boot successfully.

It is embedded into computers as a motherboard chip and is primarily responsible for booting the computer system.Īpart from booting up your computer, BIOS is responsible for a lot of other functionality behind the scenes – like managing data flow between an operating system and attached hardware devices such as printers, mouse, keyboard hard disk, and scanners.

BIOS stands for Basic Input/Output System.
