System BIOS configuration 5
• When a configuration error is detected by the system and you are prompted by a "Run Setup"
message to make changes to the BIOS settings.
NOTE: If you repeatedly receive “Run Setup” messages, the battery located on the system board
may be defective. In this case, the system cannot retain configuration values in CMOS. Ask a
qualified technician for assistance.
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 the Setup Utility to change the BIOS settings from the
default or current configuration.
Accessing 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.
During POST, press F10. If you fail to press F10 before POST is completed, you need to restart
the server and repeat this step. The first page displayed is the Main menu. Use the left (←) and
right (→) arrow keys to move between selections on the menu bar.
Navigating through the Setup Utility
Use the keys listed in the legend bar on the bottom of the Setup Utility screen to access the various
menu and submenu screens of the Setup Utility. Table 1 lists these legend keys and their respective
