BIOS firmware is based on the UEFI (Unified Extensible Firmware

Interface) Specifications and the Intel Platform Innovation Framework for EFI.

The UEFI specification defines an interface between an operating system and

platform firmware. The interface con

sists of data tables that contain

platform-

related information, boot service calls, and runtime service calls that

are available to the operating system and its loader. These provide standard

environment for booting an operating system and running pre

applications.

The diagram below shows the Extensible Firmware Interface’s location in the

you to modify hardware

configuration, e.g. change the system date and time, enable or disable a

system component, determine bootable device priority, set up personal

password, etc., which is convenient for engineers to perform modifications and

customize t

he computer system and allows technicians to troubleshoot the

occurred errors when the hardware is faulty.
