Motherboard is composed of various parts and the BIOS chip is one of them. BIOS stands for Basic Input/Output System. Without the BIOS chip, the motherboard would not be able to boot up or perform any other tasks.

In this article, you will know everything about the BIOS chip and how to identify it on your motherboard. Also, we will discuss how to update your BIOS chip if needed. Without further ado, let’s get started.

What Is A BIOS Chip?

A BIOS chip is a small electronic chip found on every computer motherboard that stores important system information. This information includes the likes of the system’s boot order, what devices are installed and other low-level settings. The BIOS chip is also responsible for initializing all the other devices in the system before handing off control to the operating system.

Moreover, the BIOS chip helps to boot up the computer and perform some basic hardware tests. Other uses of a BIOS chip are to provide runtime services to operating systems and programs, and to perform hardware configuration.

There are two main types of BIOS chip: EEPROM and Flash. EEPROM is Electrically Erasable Programmable Read-Only Memory and is used in older computer systems. Flash is a newer type of BIOS chip that can be erased and rewritten in blocks, rather than one byte at a time like EEPROM.

Identifying BIOS Chip On Motherboard

Identifying the BIOS chip on can be quite difficult for amateur computer users because it is not labeled. However, there are a few ways that you can use in identifying the BIOS chip on the motherboard.

  1. Check the Motherboard Manual

Read the motherboard manual that came with your device. In this manual, you will find information on the location of the BIOS chip as well as any other relevant information. The manual should have a diagram that shows you where the BIOS chip is located. Usually, the motherboard manual has a dedicated section that discusses the BIOS chip.

  1. Check the Motherboard Layout

If you do not have the motherboard manual, you can check the motherboard layout. The BIOS chip is usually located near the CMOS battery. It is often labelled as “BIOS” or “CMOS”.

  1. Inspect the Motherboard Physically

If you cannot find the BIOS chip using the methods above, you will need to inspect the motherboard physically. This is best done with a magnifying glass. The BIOS chip is usually small and square in shape. It is often labelled with the manufacturer’s logo.

  1. Check The Motherboard Drivers

If you still cannot find the BIOS chip, you can check the motherboard drivers. The BIOS chip is typically listed as a component in the motherboard drivers. This information can be found in the “Device Manager” on Windows.

How To Install A BIOS Chip?

Installing a BIOS chip is not a difficult task and can be done by anyone. However, you should take proper precautions to avoid damaging the BIOS chip or your motherboard.

  1. Prepare The Tools

You will need a few tools to install the BIOS chip. These include a small Phillips screwdriver, an antistatic wrist strap and a fine-pointed tweezer.

  1. Remove The Old BIOS Chip

First, remove the old BIOS chip from the motherboard. To do this, you will need to unscrew the retaining screws that hold the chip in place. Be careful not to lose the screws because they are very small. Once the screws are removed, you can carefully remove the old BIOS chip using the tweezer.

  1. Install The New BIOS Chip

Next, install the new BIOS chip. To do this, you will need to align the pins on the chip with the socket on the motherboard. Once the chip is properly aligned, you can gently push it into place. Be careful not to bend the pins on the chip. Once the chip is in place, you can screw the retaining screws back into place.

  1. Test The New BIOS Chip

Once the new BIOS chip is installed, you should test it to make sure it is working properly. To do this, you will need to boot up your computer and enter the BIOS setup utility. If the new BIOS chip is working properly, you will be able to see and change the BIOS settings.

Updating BIOS Chip

Updating the BIOS chip is a simple process that can be done using a software utility provided by the motherboard manufacturer. To update the BIOS chip, you will first need to download the appropriate BIOS update file from the manufacturer’s website. Once you have downloaded the file, you will need to run the utility and follow the instructions on the screen.

It is important to note that you should only update the BIOS chip if there is a new version available. Updating the BIOS chip unnecessarily can lead to problems and can even render your computer unusable.


Knowing how to identify a BIOS chip on a motherboard is a valuable skill that can come in handy if you ever need to replace or update the BIOS chip. By following the steps above, you should be able to easily identify and install a BIOS chip. We hope you learned something new from this article.
