I'd imagine 2K, but not NT4, and none of the DOS-based Windows (98 and earlier).
There's enough support in the later NT branch of Windows (2K/XP/Vista) to run applications that expect a real operating system under them. But the DOS branch doesn't provide much support for that. 98 and earlier really were just single-user, single-application toys.
I say that as someone who still runs 98SE and DOS7 on old hardware sometimes. They have their place and time. But no one should expect support for them in 2008.
Yeah....... all of that is pretty much what I figured.......
However, seeing it in writing on their website is clearly a lot better than an assumption. :-)
That’s all I meant.
