Installing the Infrared Drivers
-------------------------------

Note: Install the infrared drivers before you install any
      application programs that use the drivers.  Some of the
      application programs replace a part of the drivers with their
      own code.

 1. Insert the Infrared Features Diskette into the diskette drive.
 2. Open the DOS command prompt.
 3. Type A:¯ (or the drive letter for the diskette drive in your
    computer) and press ENTER.
 4. Type UINSTALL and press ENTER.
 5. Select the appropriate operating system support.
    You are prompted for the drive and path where Windows or
    WIN-OS/2 is installed.  The installation utility copies
    the following files to the directory where Windows or WIN-OS/2 is
    installed: IBMIR.DLL, IBMIR.INI, IBMIR.386, IBMIR2.DLL, and
    IBMIRVDD.SYS (for WIN-OS/2 only).

If you are using the large disk support added in Windows 95 Version
4.0095b, the installation program UINSTALL might not work.  If this
happens, do the following:
 1. Insert this diskette into drive A.
 2. Open My Computer, Control Panel, and Add/Remove Programs.
 3. Click on the Windows Setup tab, and Have Disk...   Choose A:¯
    and click on OK.
 4. Mark IBM IR driver for Windows 3.1x by clicking on the check
    box to the left of it.  Then select Install.

Windows 95 Considerations
-------------------------

The ThinkPad InfraRed port might appear as a generic COM port in the
Windows 95 Device Manager panel.  This is normal because such
conventional infrared applications as PDA interface programs often
bypass the ThinkPad driver and directly access the InfraRed port as
a COM port.

The Device Manager indicates that the IR port is also a COM port as
follows:

  Generic IrDA Compatible Device (COM1)

This message may vary depending on when the Windows 95 was released.
When the Device Manager does not recognize the IR port as a COM port,
do the following:

1. Open the DOS prompt.
2. Type CD C:¯WINDOWS¯INF and press Enter.
3. Type COPY MSPORTS.INF MSPORTS.BAK and press Enter.
4. Type EDIT MSPORTS.INF and press Enter.
5. Locate the following line:
   %*PNP0510.DeviceDesc% = NoDrv, *PNP0510 ; IR Communications Port
  Change this to:
   %*PNP0510.DeviceDesc% = ComPort, *PNP0510 ; IR Communications Port
6. Save the change.
7. From Device Manager, click on the IR port.  Select Remove and OK
   (temporarily removing the port information from the registry).
   Then select Refresh and OK.
8. Shut down and restart Windows 95.
