27. Motherboard: BIOS & related stuff
BIOS: Basic Input/Output System
BIOS software is built into the PC (boot firmware)
Stored on a non-volatile ROM chip on the motherboard
First code that is run by a PC when powered on
When the PC starts up, BIOS initialize and identify system devices (POST-Power On Self Test)
video display card, keyboard and mouse, HDD, optical disc drive and other hardware.
BIOS then locates boot loader software held on a peripheral device (designated as a 'boot device'),
Eg: hard disk or a CD/DVD,
Loads and executes that software, giving it control of the PC.
This process is known as booting, or booting up or bootstrapping.
