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.

If a fan or heat sink is attached to the CPU, don’t install an option card in the lowest 16-bit option slot.

An external device connected to the option card is not working correctly.

Make sure you are using the proper cable to securelyconnect the device to the card.

Memory Module Problems

The memory count displayed by the power-on diagnostics program is incorrect.

You may have installed the SIMMs incorrectly. They may be the wrong type or speed, or they may not be inserted all the

way. See Chapter 3 for information on installing SIMMs.

If you have installed a gold-plated SIMM in the sockets, the socket may have corroded slightly. Remove the SIMM and clean the gold-plated connection; then reinstall the SIMM.
