About
Various BIOS/UEFI-related utilities which aid in modding and/or research
Usage
Main
The "main" script provides a simple way to check and parse each of the user provided files against all utilities, in succession. It is ideal for quick drag & drop operations but lacks the finer control of the BIOSUtility method. If needed, a few options can be set, by using the command line:
usage: main.py [-h] [--output-folder OUTPUT_FOLDER] [--pause-exit] input_files [input_files ...]
positional arguments:
input_files
options:
-h, --help show help message and exit
--output-folder OUTPUT_FOLDER extraction folder
--pause-exit pause on exit
python ./main.py "/path/to/input/file.bin" --output-folder "/path/to/file extractions"
BIOSUtility
Each utility is derived from a base template: BIOSUtility. The base BIOSUtility offers the following options, applicable to all utilities:
usage: [-h] [-e] [-o OUTPUT_DIR] [paths ...]
positional arguments:
paths
options:
-h, --help show help message and exit
-e, --auto-exit skip user action prompts
-o OUTPUT_DIR, --output-dir OUTPUT_DIR output extraction directory
python -m biosutilities.ami_pfat_extract -e "/path/to/input/file1.bin" "/path/to/input/file2.bin" "/path/to/input/folder/with/files/" -o "/path/to/output_directory"
If no arguments are provided, the BIOSUtility.run_utility() method gets executed, which will request the input and output paths from the user. If no output path is provided, the utility will use the parent directory of the first input file or fallback to the runtime execution directory.
Enter input file or directory path: "C:\P5405CSA.303"
Enter output directory path: "C:\P5405CSA.303_output"
Package
All utilities form the "biosutilities" python package, which can be installed from PyPi:
python -m pip install --upgrade biosutilities
Installing the python package is the recommended way to call one or more utilities programatically, while fully controlling arguments and options.
from biosutilities.ami_pfat_extract import AmiPfatExtract
ami_pfat_extractor = AmiPfatExtract()
ami_pfat_extractor.check_format(input_object='/path/to/input/file.bin')
ami_pfat_extractor.parse_format(input_object='/path/to/input/file.bin')
from biosutilities.dell_pfs_extract import DellPfsExtract
dell_pfs_extractor = DellPfsExtract()
with open(file='/path/to/input/file.bin', mode='rb') as pfs_file:
pfs_buffer = pfs_file.read()
dell_pfs_extractor.check_format(input_object=pfs_buffer)
dell_pfs_extractor.parse_format(input_object=pfs_buffer)
It also allows to use directly the four public methods which are inherited by every utility from the base BIOSUtility class.
run_utility
Run utility after checking for supported format
run_utility(padding: int = 0) -> int
check_format
Check if input object is of specific supported format
check_format(input_object: str | bytes | bytearray) -> bool
parse_format
Process input object as a specific supported format
parse_format(input_object: str | bytes | bytearray, extract_path: str, padding: int = 0) -> int | None
show_version
Show title and version of utility
show_version(is_boxed: bool = True, padding: int = 0) -> None
Requirements
There are two main types of requirements (dependencies), depending on the utility.
Python Packages
Python packages can be installed via Pypi (e.g. pip)
python -m pip install --upgrade -r requirements.txt
python -m pip install --upgrade pefile
External Executables / Python Scripts
External executables (e.g. 7-Zip, TianoCompress, UEFIFind) and Python scripts (e.g. BIOS Guard Script Tool) need to be found via PATH.
Linux
or
sudo install "/path/to/downloaded/external/executable/to/install"
Windows
MacOS

AMI BIOS Guard Extractor
Description
Parses AMI BIOS Guard (a.k.a. PFAT, Platform Firmware Armoring Technology) images, extracts their SPI/BIOS/UEFI firmware components and optionally decompiles the Intel BIOS Guard Scripts. It supports all AMI PFAT revisions and formats, including those with Index Information tables or nested AMI PFAT structures. The output comprises only final firmware components which are directly usable by end users.
Note that the AMI PFAT structure may not have an explicit component order. AMI's BIOS Guard Firmware Update Tool (AFUBGT) updates components based on the user/OEM provided Parameters and Options or Index Information table, when applicable. Thus, merging all the components together does not usually yield a proper SPI/BIOS/UEFI image. The utility does generate such a merged file with the name "00 -- <filename>_ALL.bin" but it is up to the end user to determine its usefulness. Additionally, any custom OEM data, after the AMI PFAT structure, is stored in the last file with the name "<n+1> -- _OOB.bin" and it is once again up to the end user to determine its usefulness. In cases where the trailing custom OEM data includes a nested AMI PFAT structure, the utility will process and extract it automatically as well.
