|

Parses Panasonic BIOS Update executables and extracts their SPI/BIOS image. The utility automatically uses [Rustam Abdullaev's unpack_lznt1](https://github.com/rustyx/unpack_lznt1) tool in order to decompress the initially Microsoft LZNT1 compressed resource data.

Parses VAIO Packaging Manager executables and extracts their contents.

The utility automatically uses [Igor Pavlov's 7-Zip](https://www.7-zip.org/) tool in order to decompress the initially obfuscated Microsoft CAB compressed contents.

## **Fujitsu SFX Packager Extractor**
|

|
||||
|

<sub><sup>*Icon owned by FUJITSU*</sup></sub>
|
||||
|
||||
#### **Description**
|
||||
|
||||
Parses Fujitsu SFX Packager executables and extracts their contents. The utility automatically uses [Igor Pavlov's 7-Zip](https://www.7-zip.org/) tool in order to decompress the initially obfuscated Microsoft CAB compressed contents.
|
||||
|
||||
#### **Usage**
|
||||
|
||||
You can either Drag & Drop or manually enter the full path of a folder containing Fujitsu SFX Packager executables.
|
||||
|
||||
#### **Download**
|
||||
|
||||
An already built/frozen/compiled binary is provided by me for Windows only. Thus, **you don't need to manually build/freeze/compile it under Windows**. Instead, download the latest version from the [Releases](https://github.com/platomav/BIOSUtilities/releases) tab. To extract the already built/frozen/compiled archive, you need to use programs which support RAR5 compression. Note that you need to manually apply any prerequisites.
|
||||
|
||||
#### **Compatibility**
|
||||
|
||||
Should work at all Windows, Linux or macOS operating systems which have Python 3.6 support. Windows users who plan to use the already built/frozen/compiled binary must make sure that they have the latest Windows Updates installed which include all required "Universal C Runtime (CRT)" libraries.
|
||||
|
||||
#### **Prerequisites**
|
||||
|
||||
To run the python script or its built/frozen/compiled binary, you need to have the following 3rd party tool at the same directory:
|
||||
|
||||
* [7-Zip Console](https://www.7-zip.org/) (i.e. 7z.exe)
|
||||
|
||||
#### **Build/Freeze/Compile with PyInstaller**
|
||||
|
||||
PyInstaller can build/freeze/compile the utility at all three supported platforms, it is simple to run and gets updated often.
|
||||
|
||||
1. Make sure Python 3.6.0 or newer is installed:
|
||||
|
||||
> python --version
|
||||
|
||||
2. Use pip to install PyInstaller:
|
||||
|
||||
> pip3 install pyinstaller
|
||||
|
||||
3. Build/Freeze/Compile:
|
||||
|
||||
> pyinstaller --noupx --onefile Fujitsu_Package_Extract.py

||||
