Notes on LHPM Installing The file DOSXMSF.EXE needs to be in a directory in your PATH, such as C:\DOS The file DOSXNT.386 is needed when running under Windows. The following line needs to be added to the [386Enh] Section in the SYSTEM.INI (any line so long as it's in the [386Enh] section) eg. device=c:\dos\dosxnt.386 The directory path can be anything, so long as the file is present in that directory. Typically you can put in with the dosxmsf.exe file in the dos directory, as shown above. The system.ini can be changed by running the program sysedit.exe in your windows directory. The LHPM.EXE and JPLOT.EXE files are typically put in a directory that is also in your path. This way you can run the two programs from anywhere.
