OS/2 can be difficult to install, because of the fact that you would originally need floppy disks. I may have a solution:
Download the OS/2 Warp 4 CD, and burn all the images to a CD.
Does it work? I don't know (yet).
I will test this out, don't worry.

Although I haven't played with OS/2 in about 7 years so don't quote me on that.
