The last version | Released: active
ArcaOS (previously: Blue Lion) – a 32-bit single-user multiprocessor operating system with preemptive multitasking for the x86 architecture, built on the basis of OS/2 Warp 4.52.
Since the source code of OS/2 is closed and belongs to IBM, in November 2015, Arca Noae (English) signed a license agreement with IBM to release and sell a new distribution for modern hardware – ArcaOS 5.0.
The system is distributed in two editions – Personal (including a subscription to updates and technical support for six months) and Commercial Edition (providing a wider range of updates and priority technical support for a year).
The ArcaOS operating system can run OS/2 applications (32- and 16-bit); 16-bit Windows applications; DOS applications; ported Linux applications; some 32-bit Windows applications; Java applications; Qt 3, 4, 5, and 6 applications; REXX applications.
ArcaOS 5.1 is the first ever release of an OS/2-based operating system with the ability to boot from modern UEFI-based systems, with or without the assistance of a Compatibility Support Module (CSM). ArcaOS 5.1 includes Secure Boot certificates which may be imported into the system keystore to allow trusted booting either when ArcaOS is the only OS installed or when it is installed alongside another OS (where Secure Boot may have already been enabled).
ArcaOS 5.1 is able to install to and (under UEFI) boot from GPT disk layouts. Device capacity limitations from previous OS/2-based releases are no longer an issue or ArcaOS 5.1. Need to install to a 16TB SSD? No problem.
