The entire boot of your system is done with BIOS. BIOS loads up PS/2 connections which is typically your keyboard or mouse but most people are upgrading to USB keyboards and mouses. BIOS also boots up your harddrive which is turn boots up your Operating System.
In very old computer systems, those using DOS, the BIOS was the interface between the operating system and the hardware. But in modern systems the BIOS is of much less importance, being used only during the early stages of the boot process. While the computer is in operation the device drivers take over completely the former functions of the BIOS.

Typically changes in the BIOS are not stored on any file, but on the BIOS chip itself. This is why it is expressly important to back it up ( if supported ) when changing or flashing ( updating ) your BIOS
