SUMMARY
It is possible to run Microsoft Windows operating system version 3.0 from inside Microsoft Windows operating system version 3.1, but only in real mode. To do this safely and efficiently, create a program information file (PIF) that sets up the memory requirements for real mode Windows and runs a batch file that removes Windows 3.1 from the PATH environment variable in the AUTOEXEC.BAT file.

MORE INFORMATION
The optimal memory configuration for Windows 3.0 real mode is as follows:

  XMS memory required: 512K XMS memory desired : 512K

EMS memory required: 1024K EMS memory desired : 2048K Windows 3.1 must be removed from the PATH environment variable to ensure that no version 3.1 drivers or dynamic-link libraries (DLLs) will be loaded by Windows 3.0.

The PIF file should have a batch file as the executable filename. The batch file should at least have the following lines

...SET PATH=C:\WIN30 ...C: ...CD\WIN30 ...WIN /R where &quot;WIN30&quot; is your Windows 3.0 program directory and C is the drive that contains Windows 3.0.

Note: If the Windows 3.1 directory is on a drive other than C, it is critical to have the line &quot;C:&quot; in the batch file (where C is the drive that contains Windows 3.0).
