OS/2 2.0 uses the instruction set of the Intel 80386 microprocessor, and therefore requires a system unit equipped with either an Intel (or compatible) 80386SX (or higher) microprocessor.
IBM systems equipped with such microprocessors include:
OS/2 2.0 will not run on machines equipped with an Intel 80286 processor. Therefore, computers such as the IBM PC AT, PS/2 Model 30-286, and Models 50, 50Z, and 60 cannot be used with OS/2 2.0. However, OS/2 2.0 does support non-386 based machines that have been upgraded with a 386 or 486 processor using the Aox Micromaster, Intel SnapIn, or Kingston SX/Now! card.
IBM has tested key functions of OS/2 2.0, based on selected model configurations provided by the manufacturers of non-IBM hardware systems. Test results are available on CompuServe, Natboard, the National Support Center Bulletin Board System, the OS/2 Bulletin Board System, IBM Forums (OEM and OS2ARENA), and IBMLINK(*).
