First, navigate to the Minisforum Downloads site. You can just google this term and it should show as the first result, but here is the link I have: https://www.minisforum.cn/new/support

Navigate to motherboards and select the model you want to update. In my case, I have both the BD795M and the BD795i SE motherboards. Click > Downloads > BIOS & Firmware.

Below, I am selecting the BIOS v1.12 download.

AAfter you get the download it will be a .7z file. So you will seen something like 7-zip if you are on Windows. After extracting, you will see the following files:

When I downloaded the above package as you can see above when extracted, there is no EFI folder. When I booted from USB into UEFI it didn't like the USB key. An easy workaround I found was to download the MS-01 BIOS package which does have an EFI folder and just copy this folder into your downloaded package to the above folder after you extract it. Below is a look at the MS-01 files extracted.

After copying the EFI folder into the extracted motherboard upgrade files, this is what my folder looks like:

USB key prep

 Now that we have the files we need, we need to prepare the USB key. To do that, following the steps here to prepare it with diskpart:

diskpart
list disk
select disk X  # Replace X with the number of the disk you want to format
clean
create partition primary
format fs=fat32 quick

Run the update

1. Boot into U disk, with uefi shell (F7 to choose boot disk)
2. Use “FS0:” “FS1:” “FS2:” to find your BIOS udisk (mine below was FS6 as you can see, you just have to try and see which one it is, likely FS0 for many)
   • Use the command “ls” to check the files contained as you change to each one until you find your USB disk
3. Run EfiFlash.nsh
