OS/2 is an operating system developed by IBM. It was initially develeped as a joint project between Microsoft and IBM. However due to differences they split and MS went on to develop Windows NT. Wndows XP is based on the NT kernel.
OS/2 was never used to denote any version of Windows. You're probably thinking of Windows 95 OSR2 or Windows 95b as its also known by. OSR2 stands for Official Service Release 2.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
