 Last reviewed: November 22, 1994
Article ID: Q81320
The information in this article applies to:
  • Microsoft Windows operating system versions 3.0, 3.0a

SYMPTOMS

When Microsoft Windows version 3.0 is installed with a serial mouse on the following machines 

   KLH 386 Model 215
   KLH 286 Model 195
   Premier 286 Model 1400
the following problems may occur:
  • If the Microsoft Or IBM PS/2 option is selected for the pointing device, the mouse pointer remains frozen in the middle of the screen.
  • If the MouseSystems Or (VisiOn On ComX) option is selected for the pointing device, the mouse pointer will disappear as soon as it is moved.

CAUSE

These problems occur because the above computers have a built-in bus mouse port and the motherboard is set to access this port by default.

RESOLUTION

Disabling the built-in bus port by setting DIP switch number 3 to OFF on the motherboard of these machines corrects the above problems.

MORE INFORMATION

If a bus mouse is being used, no problems should occur.

The three machines above are referred to as "Revision 1" machines and are no longer in production.
