Each time you turn on your computer system or press the reset button, the system
compares the hardware installed in the system to the hardware listed in the system
configuration information stored in nonvolatile random-access memory (NVRAM) on
the system board. If the system detects a discrepancy, it generates error messages
that identify the incorrect configuration settings. The system then prompts you to
enter the System Setup program to correct the setting.
You can use the System Setup program as follows:
‡
To change the system configuration information after you add, change, or remove
any hardware in your system
‡
To set or change user-selectable options—for example, the time or date on your
system
You can view the current settings at any time. When you change a setting, in many
cases you must reboot the system before the change takes effect.
After you set up your system, run the System Setup program to familiarize yourself
with your system configuration information and optional settings. Dell recommends
that you print the System Setup screens (by pressing the <Print Screen> key) or write
down the information for future reference.
Before you use the System Setup program, you need to know the kind of diskette
drive(s) and hard-disk drive(s) installed in your computer. If you are unsure of any of
this information, see the Manufacturing Test Report that was shipped with your sys-
tem and is located in the Dell Accessories folder.
