ArcaOS is an operating system based on OS/2, developed and marketed by Arca Noae, LLC under license from IBM.[3][4] It was codenamed Blue Lion during its development.[5] It builds on OS/2 Warp 4.52 by adding support for new hardware, fixing defects and limitations in the operating system, and by including new applications and tools,[6] and includes some Linux/Unix tool compatibility. It is targeted at professional users who need to run their OS/2 applications on new hardware, as well as personal users of OS/2.[7]

Like OS/2 Warp, ArcaOS is a 32-bit[8] single user, multiprocessing,[9] preemptive multitasking[10] operating system for the x86 architecture.[11] It is supported on both physical hardware[12] and virtual machine hypervisors.[13]
