Many of you are asking about how to update BIOS without CPU. You have to use the BIOS Flashback to do so. Download the updated version in the BIOS flashback, and connect the flashback to the motherboard. Now give power to the motherboard through an SMPS. Lastly, press the flashback button for 3 seconds.
As the process is tricky, you may not understand it properly unless you dive deeper. Therefore, we have shared a detailed procedure. Keep on reading, and you will understand the process if you don’t want to use the CPU for the update.
We have also shared a handful of other pieces of information regarding this. So, without any further ado, let’s get started!
Step By Step To Update BIOS Without CPU
Updating your PC’s Basic Input or Output System without a CPU can be difficult and risky. And if you are doing it without a CPU, it might get even more complicated and tricky.
Almost all the motherboards come with a feature that does not require a CPU to flash the BIOS. So if you own a motherboard manufacturer model above the B550 and X570, you can flash it without a CPU. But an older motherboard may not offer this advantage.
However, if you don’t have a motherboard manufacturer model above B550 and X570, you need to connect a CPU to do the work as your PC’s mobo can’t work without the CPU. You will need a CPU to keep your motherboard running. So it’s better if you bring a CPU before updating.
If you update your BIOS with the help of your CPU, the risk of your motherboard being damaged will lessen. And updating the system for the latest BIOS version won’t even be that much complicated and tricky as it would be if you do without your CPU.
But if you still can’t manage a CPU, then it’s all right. You can go the non-CPU way. Here’s how you have to update without the help of the CPU:
You only need the USB BIOS Flashback to upgrade the system without a CPU. The USB BIOS flashback lets you upgrade the system without requiring a CPU. You can use a USB flash drive and the dedicated flashback USB drive port. The flashback USB drive port is on your back I/O panel of the PC.

Quick Info: What Is A BIOS Flashback?
Using the Flashback feature means you can go back to an older version of any software or even a newer version. Faulty operations and instability often require you to go for an older or a more recent version.
All you have to do is download the version of the software you want in the flashback, and you can connect the flashback to the motherboard’s power supply area.
Therefore, now that you know about the flashback, Here’s the complete update process without CPU:
- Step 1:
First, plug the flashback device into your motherboard.
- Step 2:
Next, you must plug in the USB flash drive with the updated, correct BIOS version for the motherboard.
- Step 3:
You must give power to the motherboard through an SMPS at this phase.
- Step 4:
Lastly, you must press the flash BIOS button or flashback button for 3 seconds.
Your work ends here. The rest of the procedure will happen automatically. But if you still face problems while doing it with the flashback, ask any professional or someone who has done this many times to do it for you. Remember to do it carefully as the BIOS is connected to your computer’s motherboard.
What Is A BIOS Update?
Motherboard BIOS is the basic input or output system of your PC. You can use it to adjust and configure your PC’s different components like RAM and fan. You can also fix various issues and add necessary features to the PC.
The primary intent behind the update is to keep everything content and compatible. Similarly, you can get the needed security updates and stability from the update. It can also help in the Windows update.
Checking The Current Version Of The Operating System: How To Do It?
Before you update, you need to check the system’s current BIOS version. Otherwise, installing the wrong BIOS update file might ruin the motherboard and will be of no potential use. Here are the steps to check the current version if you have Windows 8 or 10:

That’s all you have to do. Now you can make the necessary changes as you like.
BIOS Vs. UEFI Firmware – The Differences
You might have already heard the term UEFI alongside BIOS. UEFI is simply a modern alternative to the other system. BIOS stands for your PC’s input or output system, and UEFI stands for Unified Extensible Firmware Interface.
You will find many advanced features with UEFI as a modern alternative, but the bottom line is the same as using a BIOS. Yet there are a few differences in UEFI BIOS; let’s have a look at those:
|Full-Form||Basic Input/Output System||Unified Extensible Firmware Interface|
|Storing Area||EPROM (Erasable Programmable Read-Only Memory) Firmware||.efi File Stored On The ESP Of The Hard Disk|
|Accessing Keys||Del, F2 Or F10||Del, F2, F10 Or F12|
|Boot-Time||Average Boot-Time||Faster Boot-Time|
|Supportable Drive Sizes||2.2 Zettabytes||9 Terabytes|
|Running Mode||16bit||32bit Or 64bit|
Does My PC Need A BIOS Update?
A computer’s basic input or output program does not need an update often. The BIOS chip is in a small chip in the motherboard. Its job is to manage the basic instructions of your computer that allow it to boot into an operating system.
It is better if you are not updating Computer BIOS that often. Moreover, installing it can be even riskier than updating a small Windows program. You can update it only if there is a problem with your hardware.
As the system is located on the motherboard, if the update process goes slightly wrong, you won’t be able to turn your Windows on again. However, if you want to upgrade it, take a professional’s help or do it carefully by following our steps.
When To Give The Update?
You should avoid giving your BIOS an update because that can be very risky for your computer. If something goes wrong while updating, your PC might not work correctly. So you have to be careful while working with your system.
If you notice your computer is working fine, you don’t have to think about updating BIOS. But if you face problems like lags and need an upgrade or change, you can consider updating the system.
Again, if you want an improvement in your computer that the new version provides, you can think of updating. You should even update the BIOS if you see any critical flaws that need to be fixed up. If you intend to upgrade to a new CPU, you should consider upgrading it.
You can only upgrade the system if you want an improvement feature in your computer system, a major bug, or if your computer hardware needs an update. If your computer doesn’t have any of the above problems, consider leaving your BIOS alone. Make sure to check the system information before you proceed further.
Will Updating BIOS Improve Performance?
The system is in your motherboard and manages basic instructions to boot into an operating system. So, updating can bring more disadvantages to your computer than advantages if you are unsure of the system information and what you need. As a result, if anything happens, it automatically damages your computer’s motherboard and PC hardware.
Updating BIOS does not change your computers, like significant software updates or performance improvement. Instead, updating it might just fix a software bug or add support to a new CPU model.
Upgrading the BIOS will not make your PC work faster or add any additional features you need. Instead, sometimes updating it might bring more problems than advantages to your PC hardware. Don’t think about updating the system unless updating it will bring an improvement feature you need for your computer.
If your computer works perfectly fine, you should not modernize your BIOS. You might not even like the difference between the old and new versions on your computer.
There are even chances that you may experience new bugs and new problems in your new version. This can happen because the BIOS that came with your computer might have gone through more tests than the updated one.
What Is The Benefit Of Updating BIOS?
Updating your computer’s Basic Input/Output System can benefit if done correctly. Many people may want to update their it without any reason. But it would be best if you didn’t do that.
You should consider updating it only when you face any problems while working with your computer or want a feature improvement in your computer. A professional should do the process of updating skillfully as one wrong move can damage your computer’s motherboard.
So Now, Let’s Take A Look At The Benefits Of Updating Your BIOS:
The newer updates will correctly identify new hardware devices such as the RAM and processors
The updated BIOS has the security update feature with it. It can increase the awareness of the boot sector viruses, but it is only possible if your motherboard supports the boot sector scanning
The updated system can quickly find bugs and motherboard issues and resolve those problems. And this may even affect the speed of data transfer and processing.
Before You Update: (Some Precautions)
It’s better to be safe than sorry. That’s why here are a few tips before you proceed with the update so you won’t regret it later:
- Backup all the data:
If the update fails to work, you may lose all the data. This is not very pleasant. So you need to backup all your data somewhere safe. As a result, even if the update result does not come good, you won’t have to worry about it.
- Hard-drive configuration information:
When you record the hard drive configuration information, you won’t have to re-enter the information even if you use a different Basic Input/Output System brand. You need to record the following pieces of information:
- Sectors per track
- Backup the settings:
You should also backup nonstandard settings like HD transfer rate, parallel port, and built-in serial settings to avoid unwanted consequences.
- Read the updating manuscript carefully:
The flash BIOS download or any update kit will show you some pieces of information that you need to go through carefully. Before you proceed, you need to understand every single thing thoroughly.
- Check the system compatibility:
Often motherboards can disable the updates due to existing system protection. So you have to allow your motherboard for the change before you update the Basic Input/Output System. But make sure to undo the settings after you have completed the update.
