I’ve had OS/2 running in a virtual machine for years; specifically, a Virtual PC one. But I’ve always known that OS/2 has idiosyncracies, such that it won’t run in VMWare (although it’s getting better in VirtualBox).
By change I stumbled on the excellent site OS/2 Museum. The whole site is fascinating, and if you’re interested in the history of OS/2, or Windows, for that matter, it is a great read.
However the post that caught my eye (obviously) was Installing OS/2 in a virtual machine, which finally explained why it’s such a pain to get OS/2 going in a virtualiser.
Still, nice work – makes me want to dig out the zip file I saved it in and relive Warp 3 again, just for a while…
