How to Identify BIOS Chip on Motherboard – A Detailed Guide

The Basic Input/Output System (often abbreviated as BIOS) is located on a chip on your motherboard. The BIOS-Chip is permanently stored on your motherboard and lets you access, set up, and maintain your computer at the most basic level. But the chip can fail if you try to flash it, if a virus corrupts it, or if you set it up wrong and lose the BIOS. The BIOS is a sort of firmware, but it is permanently saved on that little chip and can only be erased by disordering the component. Thus, “how to identify BIOS chip on motherboard?”

This article explains how to identify the BIOS chip on the motherboard. Before we go into it, let me explain the functions of the BIOS. Let’s get right down to it.


Functions of BIOS

The primary function of the basic input/output system (BIOS) is to load the operating system and initialize the computer’s hardware. The BIOS provides the necessary loading instructions for the hardware. In addition, it runs a test that may help determine whether or not the computer has the minimum specifications needed to start up. Specifically, this is called a “Power ON Self-Test” or POST. The computer will begin beeping if a problem is detected during the POST test.

Here are some of BIOS’s significant functions:


First, the BIOS checks to see whether the computer hardware is working correctly and detects any problems. The Power ON Self-Test is used for this purpose. The computer will make a beep sound, indicative of the nature of the POST failure. With the POST completed successfully, the booting begins.


Once POST has been completed, the BIOS will search for and recognize the operating system. If an operating system is found, the BIOS will let it take over. The term “booting” describes this procedure.

BIOS software

The drivers for the BIOS are a group of programs kept in a programmable read-only memory chip. The Basic Input/Output System Drivers, or BIOS Drivers, provide the most fundamental system configuration data.

The BIOS Setup

It is a configuration utility that allows you to alter many hardware settings and system parameters like time, date, and security passwords.

How to Update BIOS?

Having this information is necessary. You’ll find it somewhere on the computer’s circuit board. There are various versions of the BIOS, and each one may be modified to operate with a particular make and model of computer. Keeping in mind that BIOS files are version-specific will be helpful.

If you think an updated BIOS could be available for your model, look it up on the maker’s site. Get the newest version if one is available. In the past, updating the BIOS required including a flash program inside the installation file. These days, a motherboard’s built-in utility may do the same thing as a flashing application, so you don’t need to bother with either.

What Causes BIOS to Fail?

The BIOS-Chip is permanently stored on your motherboard and allows you to access, set up, and store your computer system at the primary level. However, the chip can fail due to an attempt to flash it, a virus corrupting it, or a wrong configuration leading to missing BIOS.

Also, if you have changed the BIOS parameters to incorrect values, your BIOS chip may stop working.

The following is a step-by-step guide that will assist you in identifying and locating the appropriate BIOS for your PC.

How to Identify Bios Chip on Motherboard

Finding the BIOS chip on your PC’s motherboard can be challenging. But you’ll enjoy our step-by-step instructions.
Now that we’ve discussed what could go wrong with a BIOS let’s talk about the three ways to find the BIOS chip on your motherboard.


A BIOS chip is usually on the corner or edge of a motherboard close to the coin cell socket, called the CMOS memory. It is the one that stores the system’s BIOS configuration. The Super IO/SMC houses the CMOS Memory, a bridge between the BIOS and the rest of the computer’s hardware by storing the BIOS’s configuration data. Even though it isn’t a hard and fast rule and may be found elsewhere, it’s usually easy to find because it’s written on the motherboard PCB and has a little colored blob.


Another way to find the BIOS chip is to look for a “BIOS label” on the motherboard. The BIOS chip is easy  to find if you have the latest motherboard because it is usually while naming it UEFI BIOS, M BIOS, or something similar. Once you look at your motherboard and find the label, it’s easy to find your BIOS chip.


Lastly, read the instructions that came with your computer. A user manual lists all of a motherboard’s parts and where they go. You can quickly check it out and find out where the BIOS chip is on your model. It’s much easier to find the BIOS chip’s location if you read the manual for your motherboard or search for the model and manufacturer of your board. There will be a diagram of the motherboard’s layout in the documentation, making it easy to find the BIOS chip.

Frequently Asked Questions

How many BIOS chips does a computer have?

Most of the time, there is only one BIOS chip on a motherboard. Gigabyte is one of the few motherboard manufacturers that uses the second chip in their products (for Gigabyte motherboards, the second chip is a Backup BIOS)

How to find a BIOS manufacturer?

Using the Microsoft System Information tool, you may determine the BIOS version, the motherboard manufacturer, and the motherboard model. The components and software environment of the system is showing in System Information.

Can you turn on your computer without the BIOS?

No, because the computer won’t turn on without the BIOS. The BIOS is like the “basic OS” because it connects the most important parts of the computer and lets it boot up. The primary operating system (OS) is continue to connecting with the hardware through the BIOS while loading.


In this guide on “how to identify BIOS chip on the motherboard,” we talked about how to find the chip by looking at it, using the label to find it, or consulting the user manual. We also talked about how to look online for your computer model’s motherboard specs and the company’s design.
Hopefully, you don’t have to worry anymore. One of the methods in this article will work for you and help you find the BIOS chip on your motherboard.
