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 impleme
NTation of 1.x so bad, that 3 years after i
NTroduction you could still cou
NT 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 {Prese
NTation Manager} {graphical user i
NTerface}.
OS/2 supports
hybrid multiprocessing (HMP), which provides some eleme
NTs 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 co
NTinued to develop OS/2 2.0, while Microsoft developed what was originally i
NTended to be OS/2 3.0 i
NTo
Windows NT. In October 1994, IBM released version OS/2 3.0 (known as "Warp") but it is only dista
NTly related to
Windows NT. This version raised the limit on RAM from 16MB to 1GB (like Windows
NT). IBM i
NTroduced networking with "OS/2 Warp Connect", the first multi-user version. OS/2 Warp 4.0 ("Merlin") is a {network operating system}.
