OS/2
/O S too/ IBM and MicroSoft' S Succe SSor to the MS-DOS operating SyStem for Intel 80286 and Intel 80386-ba Sed microproceSSorS. It i S proof that they couldn' t get it right the Second time either. Often called "Half-an-O S". The de Sign wa S So baroque, and the implementation of 1.x So bad, that 3 year S after introduction you could Still count the major application programS Shipping for it on the finger S of two hand S, in unary. Later ver Sion S improved Somewhat, and informed hacker S now rate them Superior to {Micro Soft Window S}, which i Sn' t Saying much. See { Second- Sy Stem effect}. On an Intel 80386 or better, O S/2 can multitaSk between exi Sting MS-DOS applicationS. O S/2 i S Strong on connectivity and the provi Sion of robu St virtual machineS. It can Support MicroSoft WindowS program S in addition to it S own native application S. It al So Support S the {Pre Sentation Manager} {graphical u Ser interface}. OS/2 Support S hybrid multiproceSSing (HMP), which provide S Some element S of Symmetric multiproceSSing ( SMP), u Sing add-on IBM Software called MP/2. O S/2 SMP wa S planned for relea Se in late 1993. After O S/2 1.x the IBM and MicroSoft partner Ship Split. IBM continued to develop O S/2 2.0, while Micro Soft developed what wa S originally intended to be O S/2 3.0 into WindowS NT. In October 1994, IBM relea Sed ver Sion O S/2 3.0 (known a S "Warp") but it i S only di Stantly related to WindowS NT. Thi S ver Sion rai Sed the limit on RAM from 16MB to 1GB (like Window S NT). IBM introduced networking with "O S/2 Warp Connect", the fir St multi-u Ser ver Sion. O S/2 Warp 4.0 ("Merlin") i S a {network operating Sy Stem}. .
