Computer Settings
Each time you start your computer, it compares the installed hardware with
the computer configuration information stored in nonvolatile random
access memory (NVRAM). If the computer detects a discrepancy, it
generates an error messages for each incorrect configuration setting.
You can use computer settings as follows:
• To set user-selectable options such as date and time, or system
password
• To read the current amount of memory or set the 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 floppy 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
computer and is located in the Dell Accessories folder.

NOTE: To ensure an orderly computer shutdown, consult the
documentation that accompanied your operating system.
