The ReactOS project, dedicated to replicating the Windows NT operating system, has reached a new milestone by successfully booting on ARM64. This achievement, while still in an experimental state, showcases the potential of ReactOS on modern hardware.
ReactOS has been a long-standing open-source initiative, recently celebrating its 30th anniversary since the first commit to its source code. The current development efforts are primarily focused on achieving compatibility with Windows Server 2003. Unlike WINE, which provides a compatibility layer for running Windows applications on Linux, ReactOS aims to recreate the NT kernel from the ground up, including support for drivers.
Experimental Build on Raspberry Pi 5
The ARM64 port of ReactOS is currently a proof of concept, with limited functionality available. Users have reported mixed results when attempting to run it on a Raspberry Pi 5, indicating that the installation process is challenging and not suitable for inexperienced users. The ReactOS team has emphasized that this build is still in its early stages, and users should approach it with caution.
Technical Requirements and Development Efforts
To successfully boot ReactOS on ARM64, a UEFI ARM64 system with GICv2 or v3 enabled is necessary. The software supports boards from the ARMv8-A architecture onward, with the Raspberry Pi 5 being a notable case. A contributor to the project dedicated eight months to make this booting process possible, highlighting the complexity involved.
Current Limitations and Future Prospects
While the ability to reach the familiar Windows desktop is a notable achievement, the current build of ReactOS on ARM64 is still very much in its infancy. Users are advised to use it on a non-essential device, as ReactOS is classified as an alpha-quality operating system. Stability and application support are not yet robust, and the project encourages users to provide feedback to aid in its development.
In summary, ReactOS’s successful boot on ARM64 represents a significant step forward for the project, although it remains a work in progress. Users interested in exploring this experimental build should be prepared for a challenging setup process and limited functionality.
