Having a problem with your motherboard BIOS will prevent your computer from being able to begin the boot process. Do not attempt to replace your motherboard BIOS chip unless you are confident in your ability to do so.

BIOS chip identification is done by these 3 steps

1) Location

A motherboard’s BIOS chip is typically found on one of the board’s corners or edges. Keep in mind that it’s typically located near the coin-cell socket when looking for it. It is, after all, the one with the BIOS settings. Even yet, this isn’t an absolute guideline, and it may be found in another place entirely. Fortunately, it is generally marked on the motherboard’s PCB and has a little, colored blob on it, making it easier to identify.

2) Label

Another technique to identify the BIOS chip is to inspect the motherboard for a ‘BIOS’ label. This label, however, is only accessible on recent models.

3) Manual

Finally, review your computer’s instruction manual. All of the motherboard’s components and their locations are typically described.

Finding the BIOS chip’s location is a lot easier if you consult your motherboard’s manual or search for your specific board’s model and manufacturer. The motherboard documentation will include a diagram of the motherboard’s layout, making it easy to locate the BIOS chip.

 How To Identify BIOS Chip On The Motherboard

Working with electronic components can be dangerous due to their sensitivity. A computer store employee can always do a BIOS upgrade for you. Or, if possible, send the motherboard back to the manufacturer and get it replaced.

To replace the BIOS chip, you will need to locate a new BIOS chip now that you know where it is situated. To begin, look for the precise BIOS that came preinstalled on your motherboard. It’s normally printed on the chip, although it could also be in the motherboard’s user manual.

Power-on self-test (POST) is the mode your computer enters when you turn it on for the first time. The computer and its components are self-tested here by the BIOS. If it identifies a problem, it will display an error message. A self-test is then performed by the BIOS before loading the operating system from the disc into memory.

Make sure that you purchase the BIOS chip that is compatible with your motherboard. When it comes to replacing the BIOS chip, you should only do so if you are an expert. The motherboard may be permanently and irreparably damaged if the BIOS chip or the PCB around it is damaged.

At startup, the BIOS isn’t done; it also conducts other critical functions. When displaying data on the screen, it communicates with other devices like a mouse and keyboard. Using this program, you can read and write sectors to and from a hard drive or floppy disc.

Major Reason Behind Checking Your BIOS?

POST, the abbreviation for “Power-On Self-Test,” is another acronym for “BIOS.” This tells you whether or not your computer is capable of booting. If the PC is unable to perform POST, a series of sounds will alert you to the specific component in your PC that is malfunctioning.

The only way to determine if your BIOS is malfunctioning is to listen to these sounds. Now, you’ll need to remove your CPU and inspect the motherboard.


You can only use the BIOS chip to store your BIOS. The BIOS is available to the motherboard since it is a type of firmware. It’s not that difficult to identify the BIOS chip. Underneath or near the CMOS battery on the bottom right of the board, it is commonly found.

For convenience, the chip is usually marked with a sticker or dot by the manufacturer. If you are an expert, you can easily replace the BIOS chip once you know where it is located. If this is the case, why not have a computer store come in and replace it?

How To Update Your BIOS?

Having this knowledge is critical. Somewhere on the circuit board of the computer, you’ll locate it. There are a variety of BIOS versions, each of which can be tailored to a certain brand and model. You should also keep in mind that BIOS files are particular to revision numbers.

For your model, go to the manufacturer’s website and see whether the BIOS has been updated.
If a newer version is available, be sure to grab it. The old BIOS installations used a flash application in the installation file to run the setup from a USB when a command was entered. Modern motherboards have a built-in utility that eliminates the requirement for a flashing program.

In other words, the update itself and the release notes are all that’s included in the download. Before you begin, check the manufacturer’s website for instructions on how to install the BIOS update.


What is included in a BIOS?

The BIOS contains instructions on how to load the most fundamental computer components. In addition, it includes a test known as POST (Power-On Self-Test) that helps to ensure that the computer can boot up. You’ll hear a series of beeps if the computer fails the POST test. This indicates that something is wrong with the PC.

What were the first BIOS?

Gary Kildall created the first BIOS, which was incorporated in the CP/M operating system in 1974. It was the first of its kind. Kildall developed the name “BIOS” to refer to a portion of a computer’s operating system that loads during boot-up and communicates with other hardware components in the computer.

What BIOS is on my computer?

To find out what type or version of BIOS is installed on your computer, you must first enter the BIOS setup. This information should appear on the main BIOS screen, such as AMI, Award, or Phoenix, as well as what BIOS version is currently installed on the computer.
