# Test the Adapter (Optional)

| NOTE: If you are using a 64-bit processing environment (Itanium™-based computers), you should switch to the Itanium User Guide from the User Information page.

Intel's diagnostic software lets you test the adapter to see if there are problems with the adapter hardware, the cabling, or the network connection.

#### Windows* Cable Test

The cable test is available for 82550-based PRO/100 adapters without a link to the network.

1. Double-click the Intel PROSet II icon in the Control Panel or system tray.

2. In Intel PROSet II, select an Intel PRO/100 network adapter.

3. Click the General tab, then click Test Cable.

The results display in the Troubleshooting tab.

#### Windows Diagnostics

1. Double-click the Intel® PROSet II icon in the Control Panel or system tray.

2. In Intel PROSet II, select an Intel PRO/100 adapter.

3. Click the Diagnostics tab. A list of available tests will be displayed.

4. Click Run Tests. You can also select/deselect individual tests with the check boxes. If an error is detected, information about the error will be displayed.

5. Repeat steps 2 - 4 for each network adapter installed in the computer.

#### NetWare*, DOS Diagnostics

1. If you are not already at a DOS prompt, shut down the OS and start up MS-DOS*.

2. Insert the Intel CD or change to the installer directory that contains DIAG100.exe.

3. At the DOS prompt, type: DIAG100 and press Enter.

4. If you have more than one PRO/100 adapter in your computer, an Adapter Selection menu appears on the screen. From that menu, select the network adapter you want to test.

5. From the Main menu, select Test adapter and then select the type of test you want to run.

6. Repeat steps 3 and 4 for each PRO/100 adapter installed in the computer.

More information is available on the DIAG100 test utility.

#### Responder Testing

The Intel PRO/100 adapter can send test messages to another Ethernet adapter on the same network. To set up this type of responder test in Windows (98SE, Millennium, NT 4.0, 2000 and XP), see the Intel PROSet II help.
