Hi @black-raven, I have a Medion Erazer Deputy P60 MD62594, i5 12th gen, RTX 4060, BIOS version 1.07.04RMES_00018. I would like to unlock the advanced menu. How can I make the BIOS dump? Can you help me?
Hi
Need your SPI bios dump.
Check your private chat.
BIOSUtilities is a collection of various BIOS/UEFI-related utilities which aid in research and/or modding purposes.
BIOSUtilities is a Python 3 project at its core, but also relies on various external utilities and/or dependencies.
First, you must make sure that a compatible Python version (i.e. 3.10.x - 3.13.x) is installed:
Note: On Windows, avoid installing Python from the Microsoft Store and prefer the "installer" from the official website instead.
There are two main types of requirements, depending on the utility: "Python Packages" and "External Executables / Scripts".
Python packages can be installed via Pypi (e.g. pip)
python -m pip install --upgrade -r requirements.txt
or
python -m pip install pefile==2023.2.7 dissect.util==3.20
External executables and/or scripts (e.g. TianoCompress.exe, big_script_tool.py, 7z.exe) are expected to be found via the "PATH" local environment variable, by default, which is configured differently depending on the operating system.
or
sudo install "/path/to/downloaded/executable" /usr/local/bin
Note: In the "Environment Variables" window, you can modify the "Path" variable under "User variables" instead of "System variables", contrary to what many guides suggest.
Alternatively, you can create a folder named "external" at the root of the "biosutilities" project (i.e. next to "common" directory) and place all external dependencies there.
Note: On Linux, you need to compile "comextract" from sources as no pre-built binary exists.
Note: On Linux and macOS, you need to compile "TianoCompress" from sources as no pre-built binary exists.
Optionally, to decompile the Intel BIOS Guard Scripts (when applicable), you must have the following 3rd party python script at PATH or "external":
Note: On Windows, in the "Environment Variables" window, you need to add ".PY" to the PATHEX system variable, as it may not have been added when installing Python.
Unless explicitely noted, all utilities should work under Windows, Linux or macOS operating systems which have Python 3.10 - 3.13 support.
There are two different possible flows when using the BIOSUtilities project:
You can use either one or the other, depending on your needs. Most end-users should probably choose the "Main" flow, which is very simple to use and automatically attempts to process one or more input files against all available utilities in one run. The "Package" flow is for those who are more familiar with python and/or need to use the project programmatically as a library/dependency.
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 you use Linux, macOS, or the Windows command prompt/terminal, you may also call "main.py" via arguments and options, as such:
usage: main.py [-h] [-e] [-o OUTPUT_DIR] [-u UTILITY] [paths ...]
positional arguments:
paths
options:
-h, --help show this help message and exit
-e, --auto-exit do not pause on exit
-o, --output-dir OUTPUT_DIR extraction directory
-u, --utility UTILITY utility class name
python ./main.py "/path/to/input/file.bin" --output-dir "/path/to/output/folder"
python ./main.py "/path/to/input/file.bin" -e -o "/path/to/output/folder" -u AmiUcpExtract
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 either via the CLI (main.py script) or programatically (python imports, utility arguments).
biosutilities --help
biosutilities "/path/to/input/file.bin" -o "/path/to/output/folder/" -u PhoenixTdkExtract -e
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 = runtime_root()
padding: int = 0
If the required arguments are not provided, placeholder values are set so that it is 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()
AmiPfatExtract
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 -- ALL" but it is up to the end user to determine its usefulness. Additionally, any custom OEM data, after the AMI PFAT structure of "n" components, is stored in the last file with the name "<n + 1> -- OOB" and it is once again up to the end user to determine its usefulness. In cases where the data of a component 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.
AmiUcpExtract
Parses AMI UCP (Utility Configuration Program) Update executables, extracts their firmware components (e.g. SPI/BIOS/UEFI, EC, ME etc) and shows all relevant info. It supports all AMI UCP revisions and formats, including those with nested AMI PFAT, AMI UCP or Insyde iFlash/iFdPacker structures. The output comprises only final firmware components and utilities which are directly usable by end users.
Additional optional arguments are provided for this utility:

AppleEfiIdentify
Parses Apple EFI images and identifies them based on Intel's official "IBIOSI" tag, which contains info such as Model, Version, Build, Date and Time. Additionally, the utility can provide both "IBIOSI" and "Apple ROM Version" structure info, when available, as well as a suggested EFI image filename, while also making sure to differentiate any EFI images with the same "IBIOSI" tag (e.g. Production, Pre-Production) by appending a checksum of their data.
Additional optional arguments are provided for this utility:
The utility exposes certain public class attributes, once parse_format() method has been successfully executed:
AppleEfiPkgExtract
Parses Apple EFI PKG firmware packages (e.g. FirmwareUpdate.pkg, BridgeOSUpdateCustomer.pkg, InstallAssistant.pkg, iMacEFIUpdate.pkg, iMacFirmwareUpdate.tar), extracts their EFI images, splits those in IM4P format and identifies/renames the final Intel SPI/BIOS images accordingly. The output comprises only final firmware components which are directly usable by end users.
No additional optional arguments are provided for this utility.
