Setup Program Your computer retains system configuration information in the nonvolatile random-access memory (NVRAM) maintained by your computer's backup battery. Each time you turn on your computer, the system compares the installed hardware with the system configuration information stored in NVRAM. If the system detects a discrepancy, it generates an error message that identifies the incorrect configuration setting. The system then prompts you to enter the Setup program to correct the setting. You can use the Setup program as follows: • To set or change user-selectable features-for exam- ple, power management or security features • To verify information about your computer's current configuration, such as the amount of system memory • To change your system configuration information after you add, change, or remove hardware connected to or installed inside your computer Accessing the Setup Program To access the Setup program, press when prompted during start-up.
