Winflash: Free Open-Source BIOS Editor

A free, open-source software application for Windows allowing users to read and write to their BIOS firmware with a simple graphical user interface

What is Winflash?

Winflash is a free, open-source utility that enables users to read and update the BIOS firmware on their Windows PCs. Developed as an open-source alternative to commercial BIOS flashing tools, Winflash provides an intuitive graphical interface to view and configure low-level system settings that are normally inaccessible to end users.

With Winflash, users can easily dump the contents of their BIOS chip to a file, edit BIOS parameters and settings, and write the updated firmware back to the BIOS chip. This allows enthusiasts and power users to optimize performance, overclock components, enable advanced features, or fix firmware bugs and issues.

Some key features of Winflash include:

• Supports the latest UEFI and legacy Award, AMI, Phoenix, and Insyde BIOS variants.
• Automatically identifies BIOS type and model to ensure compatibility.
• Backup current BIOS contents to a file prior to any firmware flashing.
• Main interface displays system information and current BIOS version/date.
• Fine-tune DRAM settings, CPU ratios, voltages, fan profiles, boot order, and various tweaking options.

By providing low-level firmware access in an easy-to-use application, Winflash greatly simplifies the BIOS modification process for both basic and advanced users alike. And because it is open-source software, users can freely audit and build upon the codebase to best suit their needs.
