Chapter 4 AMI BIOS Setup

4-1. INTRODUCTION

The board PMB-881LF 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.
