BIOS/UEFI Modding BIOS Modding Requests

Hello,

I modded the latest bios but I can’t get it to flash, I get “Secure Flash Check Failed”. Anybody know what I have to do in order to get this to work?

Expected, mod files are not allowed to be flashed by regular known tools, due to security rules of the OEM (ASrock) and the bios vendor (AMI).

Besides a cheap or not…SPI programmer, other options on Intel base systems are the use of the Intel FPT tool, a little experience user is required when using it.
