   X399 Taichi motherboard with UEFI version 1.50 fails to upgrade.
The InstantFlash feature fails to recognize available upgrade file on EFI system partition as well as on external FAT-formatted USB stick.
Additionally, trying to install via InstantFlash Internet shows the available version.  However, every time I select the "Update" button, the result is "Internet Failure".
