SYMPTOMS

Windows NT Setup allows you to install a single pointing device. If you later use Setup to change to another pointing device, the first pointing device is disabled.

This can present a problem, especially for users with portable machines that use one mouse type when the machine is in a docking station and a different mouse type when not in the docking station.

CAUSE

This is by design.

RESOLUTION

If you have mouse support in only one of your machine's configurations, do the following:

  1. Make sure both drivers are present on the machine. Setup never deletes driver files. Once you run Setup and select Mouse Port Mouse to install drivers, they remain on the machine until you explicitly delete them from the DRIVERS directory.
  2. In Control Panel, choose the Devices icon, and make sure all relevant mouse drivers are marked with the System startup type (use the Startup button if necessary). The following table lists the mouse types and corresponding drivers for those drivers Microsoft supplies:

          Mouse Type                                        Driver
          ----------------------------------------------------------
    
          Microsoft Mouse Port Mouse (includes BallPoint)   i8042prt
          Logitech Mouse Port Mouse                         i8042prt
          Microsoft InPort Bus Mouse                        inport
          Microsoft Serial Mouse                            sermouse
          Microsoft BallPoint Serial Mouse                  sermouse
          Logitech Serial Mouse                             sermouse
          Microsoft (green buttons) or Logitech Bus Mouse   busmouse
                            

For the Compaq LTE and other machines in which one configuration involves a Microsoft Mouse Port Mouse (also known as a PS/2-compatible mouse), the solution is even simpler. The keyboard and PS/2-compatible mouse share a driver; therefore, the Mouse Port Mouse support is available without additional charge if you install the other mouse type (usually serial) during Setup, everything will work from then on with no further intervention.
