Information in the BIOS (Basic Input Output System) includes things such as power settings, installed memory, hardware details, clock settings, Access to various functions such as "wake on LAN". The initial function of the BIOS is to identify, test, and initialize system devices such as the video display card, hard disk, floppy disk and other hardware. This is to prepare the machine into a known state, so that software stored on compatible media can be loaded, executed, and given control of the PC
