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.
