The Setup Utility loads the configuration values in a battery-backed nonvolatile memory called CMOS
RAM. This memory area is not part of the system RAM, which allows configuration data to be
retained when power is turned off. The values take effect when the system is booted. POST uses these
values to configure the hardware. If the values and the actual hardware do not agree, POST
generates an error message. You must run this utility to change the BIOS settings from the default or
current configuration.
The Setup Utility has five primary menu selections, including:
• Main
• Advanced
• Boot
• Security
• Exit
To run the Setup Utility:
1. Turn on the monitor and the server.
If the server is already turned on, save your data and exit all open applications, and then restart
the server.
2. During POST, press F10.
If you fail to press F10 before POST is completed, you will need to restart the server.
The first page to be displayed will be the Main
menu showing the Setup Utility’s menu bar. Use
the left () and right () arrow keys to move between selections on the menu bar.
