Hope this helps.

BIOS is Basic Input/Output System. And it's wriiten in assembly language and is stored in some chips on your motherboard. When you turn on your CPU BIOS checks the installed devices and checks if they all work. After it checks all hardware and if everything ok it executes code in boot sector of your hard drive.
