For ASUS motherboards, they have a special feature named EZ Flash 3 and an application named AI Suite 3, through which you can easily update a motherboard’s BIOS. In this article, we are here to provide you with simple steps to update the BIOS on an ASUS motherboard.
Is My ASUS Motherboard BIOS Up-To-Date?
Before updating your BIOS, make sure that the current BIOS version is outdated. If you have recently updated your BIOS, you can ignore the update. Follow the steps mentioned below to check the BIOS version for ASUS products.
How to Update BIOS on ASUS Motherboard?
For ASUS motherboards, you can update BIOS in three different ways. Although all three of them will update the BIOS, each of them has a unique purpose.
EZ Flash 3: Updates BIOS either using the internet or the USB drive AI Suite 3: Updates the BIOS within Windows and installs them once the PC restarts. USB Flashback: Updates the BIOS without a CPU processor
Download and Extract the BIOS Update File
Follow the steps mentioned below to download the BIOS update file. Extract the BIOS update file that you just downloaded. Once the extraction process is complete, copy the extracted file with a larger file size to the USB drive. Before copying the file, make sure that you format the flash drive to the FAT32 file system. We also recommend placing the update file on the root folder of your USB drive.
Using EZ Flash
ASUS EZ Flash is a utility built into the UEFI BIOS and is only specific to the ASUS motherboard. Using ASUS EZ Flash Utility, you can use a wired connection or a USB containing the update file to update the BIOS. Follow the steps mentioned below to access ASUS EZ Flash Utility. If your motherboard has ASUS EZ Flash 2 Utility, you can only use the USB with the update file to perform a BIOS update. However, if you have ASUS EZ Flash 3 Utility, you can update the BIOS using a USB or by accessing the internet.
Using the Internet
Updating the BIOS using the internet is only possible if you have a wired connection. If you do not have an ethernet cable with internet access connected to the motherboard, this method will not work. The BIOS will automatically access the internet and download the desired BIOS update file. Once the BIOS downloads the update file, it will automatically install the BIOS update.
Using Storage Device
Using a storage device or a USB is a classic method to update your BIOS. This method can be a little complicated compared to using the internet to update as you need to download the BIOS file manually. To update, turn off the system and insert your USB drive containing the BIOS update file into your I/O panel. Then, power on the system and enter the BIOS. Once the process completes, the system will reboot. Make sure that the system does not lose power and do not press any keys that interrupt the update process. Check your BIOS version to ensure that the update process is successful.
With AI Suite 3
Using the AI Suite 3 application, you can update your BIOS within the OS itself. If you do not want the hassle of entering the BIOS to perform the update, the AI Suite 3 is the tool for you. Follow the steps mentioned below to download and install AI Suite 3. Before we start the update process, make sure you download the BIOS update file and extract it somewhere on your PC. The PC should now restart automatically and begin the update process. Do not interrupt the update process. If the process is successful, the BIOS should give you an indication saying ‘Update successfully! The system will be reset!’
Using Flashback USB
Using the flashback method, you can update the BIOS even without having the CPU chip present on the motherboard. This can be especially useful if the PC is having difficulty detecting the CPU. However, not all ASUS motherboard supports BIOS update via flashback USB. Therefore, make sure the motherboard supports USB flashback. One quick way to check this is by looking for BIOS FLBK writing on the I/O panel. Alternately, you can also refer to your motherboard’s user manual. Now, start by preparing the USB drive. Prepare USB Drive Now that the USB drive is ready, locate the flashback USB port. Locate Flashback USB port You can find the flashback USB port on the I/O panel. Usually, the flashback USB port is indicated by the word “flashback” written near the USB port. Some will have a USB port with a colored outline. If you cannot determine the flashback USB port, refer to the motherboard user manual. Update the BIOS Once you have located the flashback USB port, follow the steps mentioned below to update the BIOS. The blinking indicates that the process has started. Do not interrupt the system once the blinking LED starts. Once the blinking stops and the LED turns off, it’s a sign that the BIOS update process is complete.
