IBM and
MiCrosoft' s su
CCessor 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 se
Cond time either. Often
Called "Half-an-OS". The design was so
baroque, and the implementation of 1.x so bad, that 3 years after introdu
Ction 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 ha
Ckers now rate them superior to {Mi
Crosoft Windows}, whi
Ch isn' t saying mu
Ch. See {se
Cond-system effe
Ct}. On an
Intel 80386 or better, OS/2
Can
multitask between existing
MS-DOS appliCations. OS/2 is strong on
Conne
Ctivity and the provision of robust
virtual maChines. It
Can support
MiCrosoft Windows programs in addition to its own
native appli
Cations. It also supports the {Presentation Manager} {graphi
Cal user interfa
Ce}.
OS/2 supports
hybrid multiproCessing (HMP), whi
Ch 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 Mi
Crosoft developed what was originally intended to be OS/2 3.0 into
Windows NT. In O
Ctober 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 introdu
Ced networking with "OS/2 Warp
Conne
Ct", the first multi-user version. OS/2 Warp 4.0 ("Merlin") is a {network operating system}.
