What is OS/2?

A 32-bit operating system originally developed by IBM and Microsoft as a replacement for MS-DOS. IBM later extended OS/2 to include both server and desktop versions. IBM’s current line of OS/2 software includes the OS/2 Warp Server, the OS/2 Advanced Warp Server, and the OS/2 Warp 4 client.

OS/2 Warp in its various forms is a 32-bit preemptive multitasking operating system that supports application, file and print, groupware, and Web server configurations as well as desktop workstations. OS/2 Warp Server includes symmetric multiprocessing support and clustering technologies for high-availability server environments.

OS/2 Warp Server supports most common networking protocols and all types of clients, including Microsoft Windows, Macintosh, and AIX clients.
