The OS battle...
IBMs OS/2 was part of an effort to regain complete control of the PC market that included the new PS2 systems. In the original PC, IBM allowed MS to sell DOS to other parties and used an open architecture. Everybody started creating PC clones and IBM was loosing market share fast. So they decided to create a new platform, new hardware, new software, both completely controlled by IBM and legacy free. OS/2 was unable to run DOS applications and PS2 systems where not compatible with IDE. Oddly enough, OS/2 was optimized for 80286 processors and unable to use the 386 virtual mode. Windows 3.0 had none of these problems and quickly took the market. OS/2 Warp solved all the shortcomings. It was awesome and a better OS than Windows, but it came too late.
