Adding and replacing system board components 9-13
Updating the CMOS settings in Setup
When you add system board components, such as system memory modules, your
system's Basic Input/Output System (BIOS) detects the hardware changes and
updates the CMOS settings automatically. However, if you replace or remove
components, you might receive a message that asks you to verify if the automatic
detection changed the configuration correctly.
To verify or correct the system configuration settings, enter Setup. See the section
“Entering Setup” on page 6-4.
