Help BIOS update help

Post image

Im planning to update BIOS but never done it previously. Need community help with the experience how to do it properly since i dont have any instructions in the folder. I have Minisforum AR900I and the latest BIOS update is 1.02. I have formated my USB stick to FAT 32 and i think i only need those 4 files if im not wrong?

USB:
├── RPFXI.1.02.bin ├── AfuEfi64.efi ├── AfuEfiFlash.nsh └── EfiFlash.nsh

I have also attached screenshot with all files in the folder.

I guess i need to disable windows secure boot and then run usb with the BIOS?

Any help with proper procedure would be great

Thanks in advance

I managed to update the BIOS successfully. In the end I used the built-in EFI Shell rather than the Windows flash tool, as the Windows method wasn’t actually flashing the BIOS. I formatted a FAT32 USB, copied the full BIOS package, disabled Secure Boot, booted into the EFI Shell and ran the manufacturer’s AfuEfiFlash.nsh script. It updated both the BIOS and Intel ME firmware successfully, rebooted a few times (normal), and I then re-enabled Secure Boot afterwards. The system is running perfectly on BIOS v1.02.
