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.

The image below is from the AMI website, 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 a Series S875 AMI Motherboard (it actually says AMI123-P on the image above as an example).

If your computer does not have an AMI reference, refer to your computer providers website 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.

CPU-Z Tool In Action

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 website 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.

Click the Open Button to search for and select the ROM file you downloaded from your motherboard manufacturers website.


American Megatrends Bios Update

Click SAVE to take a copy of your existing BIOS Settings. If anything goes wrong you have an option to restore!

Click the Flash Button. The Process tab will be displayed to show you the update BIOS process in action.

When the process is complete, exit the Flash Utility and Restart Your Computer (if it doesn't restart for you).

Your BIOS is now updated to the latest version. Refer to the AMIBIOS Support web page if further support is required.

American Megatrends BIOS Update Final Thoughts

The American Megatrends BIOS Update process is a little complicated. I hope the information provided on this web page is useful. Good luck with your BIOS update.

A very useful link is to the AMI BIOS and UEFI Utilities page(Opens New Window). There is a form at the bottom of the page where you can request extra support from AMI direct.

Don't forget to take a look at part 1 of this tutorial series, which introduces you to the BIOS concept, AMIBIOS beep error codes and the BIOS Setup Utility.

Is There A Better Way Than This?

Some professionals recommend you don't update your BIOS unless absolutely necessary. This is good advice if you are a true novice.
Do you agree? Do you know of a better, easier way to update your AMI BIOS than what is described in this article?
