BIOS is an acronym that stands for “Basic Input/Output System” it is stored on the motherboard itself and is the first software to run when the computer is powered on. The BIOS performs a POST (Power On Self Test) check to verify that all components are present and functioning properly before running through the boot sequence. The BIOS normally contains a number of settings for the computer, some of which will be standard such as what the boot order should be. Other options will only be available if suitable hardware is present such as disabling touchscreen functionality or overclocking settings.
