About OS/2

OS/2 is an OS for x86 and PowerPC based computers, made with IBM and Microsoft under the leadership of Ed Lacobucci (IBM software designer).
The name starts for Operating System/2 beacuse it was introduced as the second lineup to IBM's Personal System/2 (PS/2) line of "second-generation PCs."
OS/2 was intended as a protected-mode successor of PC-DOS targeting the 80286 processor, and OS/2 shares similarity with Unix, Xenix, and Windows NT.
