Important Notes

1. It wipes the old BIOS settings, and so you would need to re-activate your Windows(if using Windows) again (wipes the activation key, needs Internet to activate again).

2. If you have the non-EMMC version of ODYSSEY-X86, before updating the BIOS, Please make sure to disable eMMC in the BIOS Settings Before and After the updates.

You may check in the BIOS main page for BIOS and EC Firmware's versions.

Latest BIOS Firmware​

SD-BS-CJ41G-300-101-K 07/26/2022 15:00:00

  • Improve overall stability.

Note: If you want the above BIOS with bifurcation feature enabled, please contact [email protected]

With bifurcation feature, you will be able to use the M.2 M-Key for 4 PCIe x1. This enables you to connect four different PCIe x1 devices to the M.2 such as multiple network ports, multiple SSDs and other expansion devices. With the normal BIOS without bifurcation feature, M.2 M-Key can be used for only one PCIe x4.

Step 1 - Download the newest version of BIOS​

Download the latest version of BIOS from here.

Step 2 - Prepare bootable USB​

Just like creating a bootable USB for installing OS, format the USB into FAT32 file system. This time, just unzip the downloaded file and copy the contents into the USB.

Step 3 - Upgrading BIOS​

The first boot up from the BIOS upgrade is relatively long, please be patient to wait, and the installed OS will launch eventually. It will take around 3 ~ 5 minutes.

  • Keep pressing F7 Key to Enter Boot Manager Screen. Select the UEFI: Built-in EFI Shell as boot device and press Enter.
  • Wait a couple of seconds to enter the EFI shell
  • You will see the following message
  • Type BIOS.nsh and press ENTER to start the update process
  • If the BIOS update was successful, you will see the following output

Step 4 - Reboot​

  • When the BIOS is upgraded, press the ON/OFF button, and you should see the blue light goes off.

  • Unplug the DC power jack and RTC battery from the ODYSSEY-X86.

  • Wait a couple of minutes

  • Plug the RTC battery and DC power jack back to the ODYSSEY-X86.

  • Press the ON/OFF button and wait patiently. You should see the blue light goes on.

Step 5 - Wait Patiently​

How to update the Embedded Controller​

The X86 also has a embedded controller that can be updated. Updating the EC has the same procedure as updating BIOS(auto-update):

  1. Download the firmware files.

  2. Save them in the root location of a FAT32 formatted USB drive.

  3. Start ODYSSEY-X86 and press F7 to enter Boot Select Mode

  4. Choose the connected flash drive (if there are 2 options for the flash drive, choose the one that starts with UEFI)

  5. Wait and it will automatically start the flashing process.

  6. Reboot the device when it's done.
