What is BIOS?
The BIOS is software embedded in the motherboard of a computer that runs automatically as soon as the computer is turned on and allows the operating system to load.
What are the main functions of BIOS?
It has several functions, but the most important is to verify that all the components necessary for the operation of the system are in optimal condition and configured with the appropriate parameters.
Its options menu allows you to modify these values at your convenience, for example, to change the boot sequence or to overclock the CPU. It also allows you to set the system time, disable certain hardware components, and more.
