Introduction

An American Megatrends BIOS Update is sometimes necessary because, like any other software, improvements are made to improve stability and performance.

You should really update your computer's BIOS when a newer version is released.

This is easier to do these days (20+ years ago it was a nightmare!). AMI and other computer manufacturers provide free Flash BIOS Utilities which update your BIOS for you when you run the program (more on this later).

However, I think the AMI instructions are not very clear for typical home computer users. This tutorial aims to make the process as clear as possible for you.

There are a few things to do first before updating your computer's BIOS.

Motherboard Identification

There are different AMIBIOS products on different computer systems. Most computer makers change the AMIBIOS code to suit their own computer models.


Modern computers now come with a new type of BIOS, called Unified Extensible Firmware Upgrade (UEFI). Click here for more details (Page Coming Soon).


The image below is from the AMI web site, and shows you how to identify whether your home computer has a native AMI approved motherboard or not.

Where it says 'BIOS from 1991-Present', there is a reference to AMI and the motherboard type, if it is a AMI approved motherboard.

This reference looks something like: AMIS875-P, signifying an Series S875 AMI Motherboard (it actually says AMI123-P on the image above as an example).

If you computer does not have an AMI reference, refer to your computer providers web site for guidance. If you require more details on this step, go to the AMI BIOS (Opens New Window) web page.

If you don't understand this step. Don't worry! Download the AMIBID (Opens New Window) motherboard identification tool. Simply install and run on your computer.

If the AMIBID utility fails, go to the CPUID (Opens New Window) web page, download and install the CPU-Z tool. This is another motherboard identification utility.

From the example above, this computer has an AMIBIOS, but it is not an AMI motherboard. In this instance, the home computer user must visit the ASRack web site and search for the BIOS update for the ALive motherboard.


This is Very Important! You must always use the BIOS update made available by your motherboards manufacturer.

AMIBIOS ROM And Flash Utility

If you determine you have an AMI motherboard, download the AMI Firmware Update Tool (Opens New Window).

Unzip the American Megatrends BIOS Update utility. Go to the AFUWIN folder (under the AMIBIOS parent folder), then either the 32-bit or 64-bit sub-folder. Left click AFUWIN.EXE.

Click OK if this disclaimer appears.
