Troubleshooting

hardware correctly. Reinstall your hardware.

unit, see Chapter 7, “Adding and removing hardware.”
If the problem is not corrected, see “Solving hardware
problems” on page 37.

properly installed. If the memory is not installed

than the 2 long-3 short beeps, or if the memory
modules are installed correctly, see “HelpWare
