Option Card Problems

If you install an option card and it is not functioning properly, check the following:

1.Is the option card installed correctly? Check the installation procedure described in Chapter 5 and also see the instructions that come with the option card. The most common problem with option cards is a loose connection. Make sure the option card is well-seated in its slot.

2. Did you set the necessary DIP switches or jumpers on the option card? See your option card manual for instructions.

3.Did you run the Setup program to redefine your computer’s configuration after installing the card? See Chapter 2.

4.If you installed a memory card in your computer, see “Post- installation Setup for Memory Cards” in Chapter 5.

5.If you installed a hard disk drive that has its controller on an option card, you may need to change the position of jumper J3 on the main system board. See “Changing Jumper Settings” in Chapter 5. Also, if your Equity 386SX came with a hard disk drive that you are no longer using be sure the cable leading from that drive to the main system board is disconnected.
