Solution:
			Mouse Hardware
			--------------

All Logitech Mice work with the IBM OS/2 mouse drivers. 
Proper installation for the various types of mice is as follows:

Serial Mouse
    Select "PC Mouse Systems Mouse" during OS/2 installation.

    BIG NOTE: In OS/2, version 1.2, if you start in DOS and use the BOOT
    program to switch to OS/2, the mouse may not work if it is not
    configured as a PC Mouse Systems Mouse. To do that, while in DOS, ]
    enter the command:

                 MOUSE PC

    (assuming MOUSE.COM is in the path). Then use the BOOT program
    to get into OS/2:

                 \OS2\BOOT /OS2

    The specific lines you need in the CONFIG.OS2 (which is renamed to
    CONFIG.SYS by BOOT):

         DEVICE=C:\OS2\PCMOU01.SYS
         DEVICE=C:\OS2\MOUSE.SYS TYPE=PCMOU$
         DEVICE=C:\OS2\COM01.SYS

    This assumes you are using COM1 as the mouse port.

    The mouse should work fine if you are in OS/2 and turn your machine
    off, then turn it on again.  CONFIG.SYS will initialize the mouse as
    a PC Mouse Systems Mouse automatically.  You only need the above
    procedure if you start in DOS and switch to OS/2 with BOOT because
    BOOT does a warm boot which does not reinitialize the mouse.

Bus Mouse, EGA-&-Mouse
	Select "Microsoft Mouse, Bus Version" during OS/2 installation
	. 

Series/2 Mouse
	Install as IBM PS/2/Microsoft Inport Mouse during OS/2 installation 


EGA-&-Mouse Board
The EGA board works well under OS/2 provided the switches are set to
make it look like a standard EGA - Autoswitching OFF, with enhanced
display (in some circumstances the board works when set to an Autosynch
display). We have AutoCAD and Windows drivers that can put the Monitor
in 640x480 mode, and they work in the DOS box, but switching to OS/2 and
back gets you a corrupted screen. OS/2 will not boot if Autoswitching is 
set to ON. 


			Mouse Software
			--------------

All of the software mentioned below can only be run in the DOS
Compatibility Box (also known as Real Mode). 

Driver
The DOS driver can only be run if the OS/2 driver is not loaded, the DOS 
driver works perfectly in the Compatibility Box.  
Customers who do not have OS/2 applications that use a mouse should use 
the DOS driver, since it appears to update the cursor more frequently, 
giving smoother motion. 
Click & Menu are both Compatible in the Real Mode.


			Logitech's Bundled Programs
			---------------------------

LOGICADD (Generic CADD)
Can only be used if the OS/2 mouse driver is not installed, because it
tries to take over the interrupt for the mouse (which is not allowed by
OS/2). It does work if the DOS driver is installed. 

Logitech Publisher (First Publisher)
Works with both the OS/2 driver and the DOS driver. 

LOGIPAINT (PC Paintbrush)
Works with both the OS/2 driver and the DOS driver. 

Logitech PaintShow
Works with both the OS/2 driver and the DOS driver. Use the EGA mode for
proper operation.
