On the Socket A board that just crapped I had 3.1, 95, 98, XP, and a Linux idstro run when there was a second drive available before loaning that out. The main thing lacking there was drivers/software for the board. I ran 3.1 briefly on a 2gb partition created there with dos 6.0. 95 was placed at first on an extended 2gb partition. When a dual boot with 98 and Linux was then tried that saw a new 50gb primary eventually replaced by.... XP. So that was to become full circle again until the drive was loaned out.
