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}. .
