Its main function is to provide the lowest-level, most straightforward hardware setup and control for the computer.

In addition, the BIOS provides some system parameters to the operating system. Changes in the system hardware are hidden by the BIOS, and the program uses the BIOS function instead of directly controlling the hardware.
