The design of Operating System/2

The design of Operating System/2™ (OS/2™) is a result of matching the requirements of IBM and its customers for a new operating system for various models of the Personal System/2® with the need for continuity with a very large body of established DOS applications. The design of OS/2 represented a significant challenge both in meeting these requirements and in making efficient use of the hardware. In this paper, the design characteristics of OS/2 are discussed.
