Setup Does Not Detect IBM Token Ring 16/4 on IBM Aptiva

• Microsoft Windows 95

SYMPTOMS

When you install Windows 95 on an IBM Aptiva computer, the IBM Token Ring 16/4 network adapter in the computer may not be detected. If the network adapter is not detected, it does not function after you install Windows 95.

CAUSE

This problem can occur if your IBM Aptiva computer contains a Sound Blaster sound card that is configured to use a base I/O address of 220. A Sound Blaster card using this base address prevents Windows 95 from detecting the IBM Token Ring network adapter.

RESOLUTION

To allow Windows 95 to detect and use the IBM Token Ring network adapter, change the base I/O address that the Sound Blaster card uses to an address other than 220. For information about how to do so, please refer to the Sound Blaster documentation or contact the hardware manufacturer.

MORE INFORMATION

This behavior can also occur with other IBM computer models, including the 350- and 750-series desktop computers. These computers contain a VIBRA 16 CT2800 sound card, with the same problem as described above.
