Troubleshooting Windows 95 (NDIS 3)

Windows 95 sometimes has trouble selecting available resources for the 3C389 PC Card, causing the 3C389 PC Card not to function. If you find that your

3C389 PC Card is not functioning, follow this procedure.

1Click Start.

2Go to the Settings menu selection and click Control Panel.

3Click System.

4Click the Device Manager tab.

5Check the 3C389 PC Card network adapters icon for for indications of a resource conflict.

The resource conflict indicator is an exclamation point inside a yellow or red circle that appears on top of the network adapter icon.

6If you see a conflict indicator, double click the 3C389 PC Card networks adapters icon.

The properties dialog for the 3C389 PC Card appears.

7Click the Resources tab of the dialog box.

There are three resources that must be correct before the 3Com TokenLink Velocity PC Card will function correctly: the Interrupt Request (IRQ), Memory Range, and Input/Output (I/O) range. The interrupt request value should be a value between 3 and 15 that does not conflict with any other devices. The memory range is often set incorrectly by Windows 95. It is recommended that the memory range be set in the 000D0000 to 000DC000 in a non-conflicting memory region. The memory range 000C0000 to 000CFFFF is often used for video caches and Windows 95 does not always exclude memory regions that are already in use. Acceptable values for the input/output range include any four consecutive values beginning at 0300.
