So while I was playing around with the idea of a Windows 3.0 powered (lol) BBS I ran into one weird thing with it swapping like crazy, and eventually depleting all my disk space!
Well when I actually used Windows 3.0 back in the day, I had a 286 so I never got to play with virtual memory. By the time I got a 386, I was using Windows 3.11 & OS/2 which in Windows you configure it with the 386 icon in the control panel. On OS/2 it’s a line in the config.sys.
But for Windows 3.0 it’s a standalone program, swapfile.exe. And the best part is that you cannot run it in 386 Enhanced mode, nor in standard (286) mode. You have to first start Windows in realmode.
