3Com Corporation 3Com Megahertz 10/100 LAN CardBus PC Card Troubleshooting Information If the PC Card diagnostic tests fail, the PC Card may not be defective. Check the following: 1. Make sure that the PC Card is operating in a notebook containing a CardBus slot. 2. Make sure that the PC Card is completely seated in its slot. 3. Make sure that your notebook is running DOS 3.1 or higher and that no device drivers or memory managers are loaded. 4. Inspect all cables and connections. 5. If you are configuring the I/O base address or interrupt request level make sure that the settings you select for these parameters do not conflict with any other peripheral or software program installed in the computer. 6. The notebook in which the PC Card may be defective. Install the PC Card in a known functioning notebook and run the tests again. 7. Replace the failed PC Card with a known working PC Card, with the same configuration. If the second PC Card fails, something is probably wrong with the test environment, not with the PC Card.
