4-1. INTRODUCTION
The board Prox-E591LF 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 menu, 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.
