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 "WIN30" 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 "C:" in the batch file (where C is the drive that contains Windows
3.0).
