Line: 15 to 15
 
  • UBU_v1817.rar (UEFI BIOS Updater) package, which includes MMTool. A tool which lets you include extra driver modules in the existing UEFI firmware.
  • The original BIOS image (M5A97-R20-ASUS-2603.CAP)
  • A USB stick, formatted as FAT32

  • A Windows PC to run MMTool (Running in Wine will probably work as well)

First, extract the UBU rar file and start MMTool.exe, click on "Load Image" and select the M5A97-R20-ASUS-2603.CAP file. Next, Click on the Browse option, next to "Module file". Select the samsung-m2-dxe file. In the "Vol. Index" field, enter: 03. Click the Insert button. Save the new BIOS image file as: M5A97R20.CAP

Flashing the new BIOS image

Changed:
<
<		Insert the FAT32 formatted USB stick and copy the new BIOS image, M5A97R20.CAP, to it. Note: the name of the file is important. The USB stick needs to be inserted into the BIOS flashback port (see the motherboard manual, lowest USB port below the network interface for the M5A97 R2.0).

<		Make sure your PC is turned off and keep pressing the BIOS flashback button on the motherboard for about 3 seconds. The BIOS flashback LED should now start blinking, which means it is being installed. When the blinking stops, your new BIOS image has been installed. Turn on your PC, check the BIOS settings and see if the Samsung XP941 SSD has been recognized by UEFI.

>		Make sure your PC is turned off and keep pressing the BIOS flashback button on the motherboard for about 3 seconds. The BIOS flashback LED should now start blinking, which means it is being installed. I think it is blinking slow when the BIOS file is being read from USB and fast when it is being written to the motherboard. When the blinking stops, your new BIOS image has been installed (this can take up to 8 minutes). Turn on your PC, check the BIOS settings and see if the Samsung XP941 SSD is recognized by UEFI.

Notes

Please note it is possible to create a BIOS update file which contains drivers for both NVME and Samsung XP941 SSDs. Insert both NvmExpressDxe_4.ffs and samsung-m2-dxe into the BIOS update file and flash it using the flashback method. See also: M5A97R20NVMEBIOS
