V.E.R.A. -- Virtual Entity of Relevant Acronyms (September 2014):

OS2 Operating System /2 (IBM, OS), "OS/2"
The Jargon File (version 4.4.7, 29 Dec 2003):

OS/2 /O S too/, n. The anointed successor to MS-DOS for Intel 286- and 386-based micros; proof that IBM/Microsoft couldn't get it right the second time, either. Often called ?Half-an-OS?. Mentioning it is usually good for a cheap laugh among hackers ? the design was so baroque, and the implementation of 1.x so bad, that three years after introduction you could still count the major apps shipping for it on the fingers of two hands ? in unary. The 2.x versions were said to have improved somewhat, and informed hackers rated them superior to Microsoft Windows (an endorsement which, however, could easily be construed as damning with faint praise). In the mid-1990s IBM put OS/2 on life support, refraining from killing it outright purely for internal political reasons; by 1999 the success of Linux had effectively ended any possibility of a renaissance. See monstrosity, cretinous, second-system effect.

OS/2 Merlin Warp /O S too/ IBM and Microsoft's successor to the MS-DOS operating system for Intel 80286 and Intel 80386-based microprocessors. It is proof that they couldn't get it right the second time either. Often called "Half-an-OS". The design was so baroque, and the implementation of 1.x so bad, that 3 years after introduction you could still count the major application programs shipping for it on the fingers of two hands, in unary. Later versions improved somewhat, and informed hackers now rate them superior to Microsoft Windows, which isn't saying much. See second-system effect. On an Intel 80386 or better, OS/2 can multitask between existing MS-DOS applications. OS/2 is strong on connectivity and the provision of robust virtual machines. It can support Microsoft Windows programs in addition to its own native applications. It also supports the Presentation Manager graphical user interface. OS/2 supports hybrid multiprocessing (HMP), which provides some elements of symmetric multiprocessing (SMP), using add-on IBM software called MP/2. OS/2 SMP was planned for release in late 1993. After OS/2 1.x the IBM and Microsoft partnership split. IBM continued to develop OS/2 2.0, while Microsoft developed what was originally intended to be OS/2 3.0 into Windows NT. In October 1994, IBM released version OS/2 3.0 (known as "Warp") but it is only distantly related to Windows NT. This version raised the limit on RAM from 16MB to 1GB (like Windows NT). IBM introduced networking with "OS/2 Warp Connect", the first multi-user version. OS/2 Warp 4.0 ("Merlin") is a network operating system. (http://mit.edu:8001/activities/os2/os2world.html).
