DESCRIPTION

This document describes what to do if the Logitech mouse does not work 
after installing OS/2 or after a Dual Boot from DOS. It also describes 
how to add a Logitech mouse.

RESOLUTION

Logitech Mouse Does Not Work after OS/2 Installation
----------------------------------------------------
You might need to select another mouse driver. Before 1991, Logitech 
sold "C-Series" (CA or C7) serial mice. Since 1991, Logitech has sold 
only "M-Series" Microsoft-compatible serial mice. To determine which 
series you have, look at the bottom of the mouse. Use Selective Install
to select the correct Logitech mouse driver.

Logitech Mouse Does Not Work after a Dual Boot from DOS
-------------------------------------------------------
Your mouse might be running in a mode set by a DOS-based mouse device 
driver. If the COM2 port is being used, switch back to DOS; then type 
either MOUSE PC or MOUSE 2 PC and press Enter.

This resets the mouse to a mode recognized by OS/2.

Note: You must use the MOUSE.COM that came with the mouse.

Adding a Logitech Mouse
-----------------------
1. At an OS/2 command prompt, type E CONFIG.SYS to edit the CONFIG.SYS
   file.

2. Ensure the following statements are present (x is the drive where 
   OS/2 is installed; y is the COM port the mouse is using):

   For the C series mouse:

      DEVICE=x:\OS2\MDOS\VMOUSE.SYS
      DEVICE=x:\OS2\POINTDD.SYS
      DEVICE=x:\OS2\PCLOGIC.SYS SERIAL=COMy
      DEVICE=x:\OS2\MOUSE.SYS TYPE=PCLOGIC$

   For the M series mouse:

      DEVICE=x:\OS2\MDOS\VMOUSE.SYS
      DEVICE=x:\OS2\POINTDD.SYS
      DEVICE=x:\OS2\MOUSE.SYS SERIAL=COMy

   For the bus mouse:

      DEVICE=x:\OS2\MDOS\VMOUSE.SYS
      DEVICE=x:\OS2\POINTDD.SYS
      DEVICE=x:\OS2\MOUSE.SYS
