Modules with BIOS Region/Setup only inside the flash can be updated with AFU utilities (usually 1-3MB BIOS binary file
size) directly. Modules with Intel® Management Engine, Ethernet, Flash Descriptor and other options additionally to
the BIOS Region (usually 4-16MB BIOS binary file size) requires a different update process with Intel Flash Utility FPT
and a wrapper to backup and restore configurations and the MAC address. Therefore it is strongly recommended to use
the batch file inside the BIOS download package available on EMD Customer Section.
