How to flash motherboard BIOS?

To ensure that your mining rig runs smoothly, it is very important that you have a good motherboard. With some problems involving multiple graphics cards, you can resolve them by setting the right motherboard options. However, sometimes the settings alone won’t give you optimal results. You might need to tweak them. You may need to flash your motherboard’s BIOS.

BIOS – Basic Input / Output System. This is software that runs on a small memory chip inside the motherboard. BIOS firmware is usually stored on a CD or USB drive.

Updating the BIOS is similar to installing an update for your operating system, but the BIOS software is not installed on the hard drive, so it’s a different process.

There are several reasons why flashing the motherboard BIOS is not recommended. As miners, you’ll probably need to do this so that you can use the newest processors that aren’t supported by your current BIOS. If everything goes smoothly, don’t update the BIOS.

Before continuing, you should know that flashing the BIOS may render the motherboard inoperative and you won’t be able to use it anymore. In addition, the warranty will be void in most cases. I am not responsible for any damage caused by our products.

When performing BIOS flashing, there are two important things to keep in mind:

  1. Make sure you choose the right BIOS for your motherboard from a reputable source!
  2. DO NOT shut down the computer during the firmware update.

These are the two riskiest steps in firmware development.

Step 1: Finding the correct BIOS.    

To find out where to change the settings on your motherboard, visit its manufacturer’s website and look under the “motherboard” section. To find out which motherboard you have, look at the EAN or serial numbers. Different motherboards may have the exact same model name but different revisions. Check the revision (or version), not just the date.

Step 2: Boot BIOS.

Make sure you download the latest firmware. Please double check if you’re downloading the correct BIOS for the model (and revision) you own! If you update the firmware incorrectly, you could damage your motherboard. Copy the content to an external hard drive. You should use a clean, file-less USB stick (FAT 32 format).

Step 3: Flash BIOS.

We use an ASUS motherboard in this guide. If you’re using a motherboard from another manufacturer, you may need to adjust some settings before you get started.

Use this guide for reference only.

  1. Copy the downloaded files to a USB stick.
  2. After you’ve copied the BIOS to the flash drive, restart your computer. Keep pressing End or F12 on your computer’s keyboard until you reach the BIOS. To see the exact motherboard model and its current firmware version, go here. Press F7 to enter Advanced Mode.
  3. Click on the tab “Tools” and then click on the Flash 3 utility. Each motherboard manufacturer has its own unique method of installing the BIOS.
  4. Select the update method by using the storage device.
  5. Click on the file.CAP on the storage device and choose it.
  6. Make sure that the BIOS file you are going to flash is correct before clicking Yes.
  7. Pressing the button will start the firmware.
