I got the OS/2 Warp Connect, thanks Tony, and went and installed it.
PS/2 mouse wouldn't work, so I switched to a serial one.
It detected the video card as an ATI which it was, but when it asked for screen resolution I choose 1024x768 and now I cannot see anything. How do I reset it or switch to 640x480? In Windows 9X there is a safe mode, does OS/2 have a safe mode?
