This appendix describes the System Setup program, which you can use to configure
your computer as well as enable and disable your computer's password features.
Your computer retains system configuration information in the nonvolatile
random-access memory (NVRAM) maintained by your computer's reserve battery.
Each time you turn on your computer, it compares the installed hardware with the
system configuration information stored in NVRAM. If the computer detects a
discrepancy, it generates an error message that identifies the incorrect configuration
setting.
You can use the System Setup program as follows:
To set or change user-selectable features—for example, your password or power
management features
To verify information about your computer's current configuration, such as the
amount of system memory
For some options, you must reboot the computer before any changes take effect.
Changes for other options take effect immediately.
NOTE: If you change an option that is activated by rebooting, the System Setup
program displays the setting you selected rather than the setting currently in effect.
You must reboot the computer for the new setting to take effect.
After you set up your computer, run the System Setup program to familiarize yourself
with your system configuration information and optional settings. Dell recommends
that you write down the information for future reference.
NOTE: If the computer uses the Microsoft Windows NT 4.0 or Windows 98 operating
system, you must use the System Setup program to view and change your system
configuration.
