10.3 Logitech Mouse . Some Logitech mouse models are detected as "Microsoft or IBM PS/2" mouse models by the Setup program. In this case, Setup will install the mouse driver for the Microsoft or IBM PS/2 mouse. If you have a Logitech mouse, you should use the Logitech mouse driver instead. To install the Logitech mouse driver, run Windows Setup from the Main group, and then select Logitech from the list of Mouse options. For more information about using Setup after you have installed Windows, see Chapter 15, "Maintaining Windows with Setup," in the Microsoft Windows User's Guide. . When installing the Logitech mouse driver, Windows Setup copies the LMOUSE.COM file to your Windows directory. This is the mouse driver that is required in order to use the Logitech mouse with non-Windows applications. To use your mouse with non-Windows applications, you need to load LMOUSE.COM before you start Windows. You can do this by adding it to your AUTOEXEC.BAT file. You will also need to add the following line to the [386Enh] section of your SYSTEM.INI file: local=PC$MOUSE .
