[SOLVED] Trying To Update My Motherboard's BIOS

[ddogg26]

Just got a Gigabyte B450M DS3H for my Ryzen 3600. I have to update the motherboard's BIOS before the cpu can work with it though. I downloaded the F40 driver from the website, but when i run the autoexec.bat file or the Efiflash.exe file, it comes up with the error 'Unsupported 16-Bit Application' 'Cannot start or run due to incompatibility with 64-Bit versions of Windows.

There was only one option for the driver on the website.
Am I just updating the BIOS wrong?

Guide on how to use the Efi Flash Tool

You need to create a bootable drive using a USB stick, then update the BIOS using the EFI Flash Tool through DOS.

Check here for help in creating Bootable USB Pendrive: http://rufus.akeo.ie/

Download the BIOS File for your motherboard and save it to your desktop so that you can find it easily. Double click on the 7Zip file (it is self extracting) and it will put the 3 download files onto your desktop for you. You only need the EFI Flash Exe file and the BIOS File, the Autoexec file can be discarded. Make a note of the BIOS File name as you will need this information later in the process and if you don't get this part correctly you will not be able to update the BIOS.

Create the Bootable Pendrive using the Rufus program.

Copy the Efiflash exe and BIOS files onto the USB Pendrive

Reboot the PC and press F12 to go to the BOOT Menu.

Select the USB Pendrive and press enter, this will take you into the DOS environment.

At the C:/ prompt type: Efiflash and press enter. This will start the Efiflash tool.

At the C:/ prompt type: efiflash xxxxxx.xx (replace the x's with the name of your BIOS File that you noted earlier) IMPORTANT: Make sure that you insert a space between the words efiflash and the BIOS name. Also make sure you enter the full point (.) before the BIOS version number. Press enter.

The BIOS Flashing process is now done and there is no further input required. The first stage you will see that the BIOS is being erased. The 2nd stage the BIOS is written and the 3rd stage the BIOS is verified. DO NOT power down or reset the PC whilst this process is happening. Once the BIOS update has been verified the PC will automatically go into a shutdown/restart/shutdown/restart sequence. DO NOT PANIC, this is normal.

Once this sequence has finished you can enter BIOS and make any changes you require, as you normally would.
