    Your system may need to operate at the slower processor speed to access the device. Try reducing the processor speed (see Chapter 2). Make sure you install option cards that meet the system’s power requirements. See Appendix A. Make sure the option card is not touching any other card. Also make sure the card isn’t touching the CPU or any fan or heat sink you have attached to the CPU.
