4.1 Introduction
The board
BE-0966
uses an AMI Aptio BIOS that is stored in the Serial Peripheral Interface
Flash Memory (SPI Flash) and can be updated. The SPI Flash contains the BIOS Setup program,
Power-on Self-Test (POST), the PCI auto-configuration utility, LAN EEPROM information, and
Plug and Play support.
Aptio is AMI’s BIOS firmware 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 consists
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-boot applications. Following
illustration shows Extensible Firmware Interface’s position in the software stack.
EFI BIOS provides an user interface allow users the ability to modify hardware configuration,
e.g. change system date and time, enable or disable a system component, decide bootable device
priorities, setup personal password, etc., which is convenient for modifications and
customization of the computer system and allows technicians another method for finding
solutions if hardware has any problems.
