Once the process completes, the utility will yield a raw binary file. You can verify the success of the extraction by checking:
An extracted BIOS Guard update package often contains only the BIOS region of the firmware. A complete motherboard SPI chip image consists of multiple regions: (Information about chip layout) Intel ME/TXE Region (Management Engine firmware) BIOS Region (The part you just extracted)
Recovering a corrupted motherboard via an external SPI programmer. Technical Architecture of BIOS Guard Containers ami bios guard extractor
AMI BIOS Guard Extractor a specialized tool used to parse and extract firmware components from images protected by Intel BIOS Guard (formerly known as —Platform Firmware Armoring Technology).
Before diving into the extractor, it is crucial to understand what it is extracting. AMI PFAT (Platform Firmware Armoring Technology) is a mechanism designed to protect the BIOS/SPI flash from unauthorized updates or modifications. Once the process completes, the utility will yield

The output files will be saved to the directory you specified in the extract_path argument.
The is a specialized utility designed to parse and extract firmware components from American Megatrends (AMI) BIOS images that are protected by Intel BIOS Guard (formerly known as PFAT —Platform Firmware Armoring Technology).
