Updating OS/2 Warp 4

IBM OS/2 Warp 4 is a classic when we talk about OS/2. On this page we will try to list all the IBM fixpacks and files available for OS/2 Warp 4 to have it to the last level available. Just some kind of "If Warp 4.1 exists, which fixes should it have". This list only covers the English language of this OS.
