Using the AMI* Video BIOS Utility

Introduction

The AMI* Video BIOS Utility (AVBU*) is a command line utility that can extract, replace, insert, and delete PCI video option ROM modules from a ROM image file. This utility is used in conjunction with the Intel^® Embedded Media and Graphics Driver (Intel^® EMGD) CED utility. CED can be used to generate a customized video BIOS (VBIOS) ROM file that meets your specific display settings. AVBU can then be used to merge the VBIOS ROM image with the hardware platform system BIOS ROM image.

This utility is provided by American Megatrends Incorporated* (http://www.ami.com), and is designed to work only on the specific hardware platform listed below. For other platforms, please contact your hardware platform supplier. To obtain a copy of this utility, please visit http://www.ami.com/crownbayavbu/ and register for your copy free of charge.

Supported Hardware Platforms

Currently the utility exclusively supports the Intel^® Atom™ Processor E660 with Intel^® Platform Controller Hub EG20T Development Kit.

Scope

The AVBU command line utility uses an internal table to control whether an option ROM can be added or removed from the image, depending on its Firmware ID, Firmware GUID, and the vendor and device IDs of the module.

This version of AVBU is designed to work specifically with the Intel^® Atom™ Processor E660 with Intel^® Platform Controller Hub EG20T Development Kit; it will not function on other platforms.

Features

• Filtered access: an internal table controls access to option ROM modules based on the identity of the BIOS and the module vendor and device identifiers. If there is no table match, the program issues the error message: “Access denied”

• Extract or copy a video option ROM

• Insert or Replace existing video option ROM

• Delete video option ROM
