Slashdot reader martiniturbide writes:ArcaOS 5.1.0 is an OEM distribution of IBM's discontinued OS/2 Warp operating system. This new version of ArcaOS offers UEFI compatibility allowing it to run in modern x86 hardware and also includes the ability to install to GPT-based disk layouts.
At OS2World the OS/2 community has been called upon to report supported hardware, open source any OS/2 software, make public as much OS/2 documentation as possible and post the important platform links. OS2World insists that open source has helped OS/2 in the past years and it is time to look under the hood to try to clone internal components like Control Program, Presentation Manager, SOM and Workplace Shell.
