Dell PowerEdge 4300 User Manual page 67

Each time you turn on or reboot your computer system, 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
To enable or disable all integrated devices in your system
You can view the current settings any time you run the System Setup program. When
you change a setting, the system reboots automatically so that the change can take
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. You can access the Manufacturing Test Report via the Dell Accessories folder.
