IBM 16/4 Token Ring PCMCIA Network Card May Need Enabler

• Microsoft Windows 95

SYMPTOMS

When you use an IBM Token Ring PCMCIA network adapter in MS-DOS mode, the adapter may not function and the computer may not be connected to the network.

CAUSE

This network adapter requires an IBM enabler to work properly in MS-DOS mode.

RESOLUTION

Load the real-mode enabler in the Config.sys file. To do so, follow these steps:

1. Use any text editor (such as Notepad) to open the Config.sys file.

2. Add the following line to the Config.sys file

         device=<path>:\pointtr.sys
   

   where <path> is the path to the Pointtr.sys file.

   NOTE: This line should be the first line in the Config.sys file. Do not load real-mode card service drivers or socket service drivers in the Config.sys file.

3. Remove any other socket or card drivers you may have installed with your PCMCIA cards, as these conflict with the IBM driver. If you are unsure of which lines to remove, consult the documentation included with your PCMCIA hardware, or contact the hardware manufacturer.

4. Save and then close the Config.sys file.

5. Restart your computer.

This problem does not occur when you use the 32-bit Windows 95 PCMCIA drivers. For more information about configuring the IBM 16/4 Token Ring PCMCIA network adapter in MS-DOS mode, please contact IBM.
