Option Card Problems If you install an option card and it does not function properly, check the following: 1. Is the option card installed correctly? Make sure it is well-seated in its slot. Check the installation procedure described in Chapter 6 and also see the instructions that come with the card. 2 . Did you set the necessary DIP switches or jumpers on the option card? See the card's manual for instructions. 3 . Did you set the necessary jumpers on the main system board? See Chapter 6 for more information. 4. Did you run the Setup program to redefine your computer's configuration after installing the card? See Chapter 2. 5 . Did you install a network option card in your computer? Some network option cards require your computer to generate an early input/output ready signal to operate properly. If you have trouble using your network card, set jumper JP15 on the main system board to position A to enable the early input/output ready signal. Then try using the network card again. If it still does not operate correctly, contact your dealer. 6 . If you used the option card to add an external device to your computer, did you use the proper cable to connect the device to the connector on the back panel? 7 . Did you perform the correct setup procedures for the software you are using with the option card? See your option card or software manual for instructions. B - 2 6 Troubleshooting
