Various BIOS/UEFI-related utilities which aid in modding and/or research
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 "Package" method. If needed, a few options can be set, by using the command line:
usage: main.py [-h] [-e] [-o OUTPUT_DIR] [paths ...]
positional arguments:
paths
options:
-h, --help show help and exit
-e, --auto-exit do not pause on exit
-o OUTPUT_DIR, --output-dir OUTPUT_DIR extraction directorypython ./main.py "/path/to/input/file.bin" --output-dir "/path/to/file extractions"If no arguments/options are provided, the "main" script requests 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"Each utility is derived from a base "BIOSUtility" template and all utilities form the "biosutilities" python package, which can be installed from PyPi:
python -m pip install --upgrade biosutilities[pefile,lznt1]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(input_object='/path/to/input/file.bin', extract_path='/path/to/output/folder/')
is_supported = ami_pfat_extractor.check_format()
is_extracted = ami_pfat_extractor.parse_format()from biosutilities.dell_pfs_extract import DellPfsExtract
with open('/path/to/input/file.bin', 'rb') as pfs_file:
pfs_data = pfs_file.read()
dell_pfs_extractor = DellPfsExtract(input_object=pfs_data, extract_path='/path/to/output/directory/', padding=8)
is_supported = dell_pfs_extractor.check_format()
is_extracted = dell_pfs_extractor.parse_format()Each BIOSUtility expects the following required and optional arguments to check and/or parse a given file format:
input_object: str | bytes | bytearray = b''extract_path: str = ''padding: int = 0If the required arguments are not provided, it is still possible to use the BIOSUtility-inherited instance to access auxiliary public methods and class constants. However, checking and/or parsing of file formats will not yield results.
Once the BIOSUtility-inherited object is initialized with arguments, its two public methods can be called:
Check if input object is of specific supported format
is_supported: bool = check_format()Process input object as a specific supported format
is_extracted: bool = parse_format()Unless explicitely noted, all utilities should work under Windows, Linux or macOS operating systems which have Python 3.10 - 3.12 support.
There are two main types of requirements, depending on the utility.
Python packages can be installed via Pypi (e.g. pip)
python -m pip install --upgrade -r requirements.txtpython -m pip install pefile==2023.2.7 dissect.util==3.18External executables and/or scripts (e.g. TianoCompress.exe, big_script_tool.py, 7z.exe) need to be found via the "PATH" environment variable, which is configured differently depending on the operating system.
Alternatively, if neither modifying PATH environment variable nor copying the executables in standard OS PATH directories is an option, you can create a folder "external" at the root of the "biosutilities" project.
or
sudo install "/path/to/downloaded/external/executable/to/install" /usr/local/binNote: In the "Environment Variables" window, you can modify the "Path" variable under "User variables" instead of "System variables", as many guides suggest.

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.
No additional optional arguments are provided for this utility.
