• Python 3.11 or greater is required to run the raw Python code (DellBiosTools.pyw)
• Windows 10/11 recommended for EXE build and usage

🚀 Quick Build (Recommended)

To create a standalone EXE without worrying about Python setup:

1. Download this repo as ZIP and extract it.

2. Double-click:

   builddellbiostools.bat

3. The script will:

   • Check if Python is installed
   • If missing, install it automatically
   • Upgrade pip and install PyInstaller
   • Compile DellBiosTools.pyw into a standalone EXE
   • Embed the custom icon from the icon folder (if present)
   • Rename the EXE with a timestamp so Windows Explorer always shows the correct icon
   • Place the finished EXE in the project folder

When it finishes, you’ll see something like:

DellBiosTools.exe

in the same folder. ✅

🔧 Manual Build (Advanced)

If you prefer to build manually:

1. Install Python 3.12+ from: https://www.python.org/downloads/windows/ (Check “Add Python to PATH” during install)

2. Open Command Prompt in this repo folder.

3. Upgrade pip and install PyInstaller:

   pip install --upgrade pip pip install pyinstaller

4. Build the EXE:

   pyinstaller --noconfirm --onefile --windowed --icon icon\DellBiosTools.ico DellBiosTools.pyw

5. The EXE will appear at:

   dist\DellBiosTools.exe

6. (Optional) Clean up temporary build files:

   rmdir /s /q build rmdir /s /q dist del DellBiosTools.spec

👉 Always back up your BIOS before patching and test in a safe environment.

⚠️ Important Note: Building the EXE with PyInstaller may trigger antivirus false positives. This is a common issue with Python-packed executables. If flagged, add an exclusion for the folder or use the raw Python version (DellBiosTools.pyw) instead.
