Could you help me to get access to the hidden advanced menu on my Acer Nitro 5 AN517-54 laptop?

Thanks in advance!

Hello, I have an ERAZER Deputy 15 P1 MD62764 laptop... Could you please help me unlock?

Hi, @Black-Raven
I have a Lenovo IdeaPad G50-70.
I upgraded the hard drive to an SSD, added 16GB of RAM, replaced the screen with a higher-resolution IPS display, and I'm now learning Linux. I installed CachyOS and I'm thrilled with the computer's speed, but the old Broadcom Wi-Fi 5 card doesn't work with Linux, so I bought the new Wi-Fi 6 AX210.

It's a shame to throw this computer away; we need to recycle because we're going to destroy the planet if we keep consuming so much. Please help, remove the whitelist.
Thank you, thank you so much for your help.

BIOSUtilities

Description

BIOSUtilities is a collection of various BIOS/UEFI-related utilities which aid in research and/or modding purposes.

Installation

BIOSUtilities is a Python 3 project at its core, but also relies on various external utilities and/or dependencies.

Python

First, you must make sure that a compatible Python version (i.e. 3.10.x - 3.13.x) is installed:

1. Download the latest official Python 3.13.x installer
2. During installation, make sure that the Optional Features "pip" and "py launcher" are both selected
3. In the Advanced Options, make sure to "associate files with Python" and add to "environment variables"
4. Once installation is complete, make sure you install all "Python Packages" and "External Dependencies"

Note: On Windows, avoid installing Python from the Microsoft Store and prefer the "installer" from the official website instead.

Requirements

There are two main types of requirements, depending on the utility: "Python Packages" and "External Executables / Scripts".

Python Packages

• pefile
• dissect.util

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 / Scripts

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.

Setup "PATH" on Linux

Linux Path

or

sudo install "/path/to/downloaded/executable" /usr/local/bin

Setup "PATH" on Windows

Windows Path

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.

Setup "PATH" on MacOS

Mac Path

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.

• 7-Zip (i.e. 7z.exe for Windows or 7zz for macOS or 7zz, 7zzs for Linux)
• UEFIFind (i.e. UEFIFind.exe for Windows or UEFIFind for Linux/macOS)
• UEFIExtract (i.e. UEFIExtract.exe for Windows or UEFIExtract for Linux/macOS)
• TianoCompress (i.e. TianoCompress.exe for Windows or TianoCompress for Linux/macOS)
• ToshibaComExtractor (i.e. comextract.exe for Windows or comextract for Linux/macOS)

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":

• BIOS Guard Script Tool (i.e. big_script_tool.py)

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.

Compatibility

Unless explicitely noted, all utilities should work under Windows, Linux or macOS operating systems which have Python 3.10 - 3.13 support.

Usage

There are two different possible flows when using the BIOSUtilities project:

• Main (simple)
• Package (advanced)

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.

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 "Package" method.

1. Download or clone the repository to a local directory
2. Install the requirements ($PATH or "external" directory)
3. Drag and drop one or more files to the "main.py" script

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"

Package

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()

Arguments

Each BIOSUtility expects the following required and optional arguments to check and/or parse a given file format:

input_object (required)

input_object: str | bytes | bytearray = b''

extract_path (required)

extract_path: str = runtime_root()

padding (optional)

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.

Methods

Once the BIOSUtility-inherited object is initialized with arguments, its two public methods can be called:

check_format

Check if input object is of specific supported format

is_supported: bool = check_format()

parse_format

Process input object as a specific supported format

is_extracted: bool = parse_format()

AMI BIOS Guard Extractor

AmiPfatExtract

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 -- 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.

Arguments

No additional optional arguments are provided for this utility.
