'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.'

The one and only time I came across OS/2 was in the late 90s (at a bank)...
