Intel FPT tool has nothing to do with AMI tools, 2 different companies, 2 similar tools but different approaches, Intel tool not intended for end-user, AMI tool as option for end-user when OEM doesn’t provide it or included own flash tool.
Every “enthusiast” user comes to a forum with a mod request… but in these modern days and technologies, it requires much more “tricks” to bypass security measures implemented by the UEFI specification and firmware providers, to flash the mod itself.
So different approaches have to be taken and not always equal to all kind of system boards and firmware (aka BIOS->UEFI Firmware) types, this will envolve the use of several tools in one way or another… why?, because as the firmware is modified, regular OEM or official flash tools will prevent it as its considerate a hack, breach, intrusion etc etc…
The cmd you show in your capture screen, is not valid to the Intel FPT tool and its placed in the end of it (-bios), this flag tells the tool to flash ONLY the bios_region, when entered like you did, the flag is invalid and the tool flashes the given data to the whole IC…
The IC SPI firmware of the system has several regions…can you picture it now!!!
