Each time you start your computer, it compares the installed hardware with the system configuration information stored in nonvolatile random-
access memory (NVRAM). If the system detects a discrepancy, it generates an error messages for each incorrect configuration setting.
You can use system settings as follows:
l
To set user-selectable options such as date and time, or system password
l
To set the current configuration information such as the amount of memory or type of hard drive installed
You can view the current settings at any time. Dell recommends that you print the system setup screens (by pressing <Print Screen>) or record the
information for future reference.
Before you use system setup, you need to know the kind of diskette drive(s) and hard drive(s) installed in your computer. If you are unsure of this
information, see the Manufacturing Test Report that was shipped with your system and is located in the
Dell Accessories folder.

of the basic input/output system (BIOS).
l
Options — a scrollable box listing options that define the configuration of your computer, including installed hardware, power conservation,
and security features.
Fields to the right of the option titles contain settings or values. Those you can change appear bright on the screen. Those you cannot
