What are some functions of BIOS?

BIOS is a significant part of a computer. It’s primary function is to is to boot up the operating system. In order to do it, it must first identify and test all hardware components, such as monitor, keyboard, processor, hard drive, other optical drive, etc. It will then load the operating system and then transfer control to it. Additionally, it will also load the drivers for the hardware components to ensure that the operation system can detect and control them.
