Chapter 4 BIOS Setup

4-1. INTRODUCTION

®
The board BM-0947 (with Intel H81) 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.
