System Utilities

CMOS Setup Utility

CMOS setup is a hardware configuration program built into the system ROM, called the complementary metaloxide semiconductor (CMOS) Setup Utility. Since most systems are already properly configured and optimized, there is no need to run this utility. You will need to run this utility under the following conditions.

•When changing the system configuration settings

•When redefining the communication ports to prevent any conflicts

•When modifying the power management configuration

•When changing the password or making other changes to the security setup

•When a configuration error is detected by the system and you are prompted ("Run Setup" message) to make changes to the CMOS setup

NOTE: If you repeatedly receive Run Setup messages, the battery may be bad. In this case, the system cannot retain configuration values in CMOS. Ask a qualified technician for assistance.

CMOS setup 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.

Before you run the CMOS Setup Utility, make sure that you have saved all open files. The system reboots immediately after you close the Setup.

NOTE: CMOS Setup Utility will be simply referred to as “BIOS”, "Setup", or "Setup utility" in this guide.

The screenshots used in this guide display default system values. These values may not be the same those found in your system.

Entering CMOS setup

1.Turn on the computer and the monitor.

If the computer is already turned on, close all open applications, then restart the computer.

2.During POST, press Delete.

If you fail to press Delete before POST is completed, you will need to restart the computer.

The Setup Main menu will be displayed showing the Setup’s menu bar. Use the left and right arrow keys to move between selections on the menu bar.

NOTE: Grayed-out fields are not user-configurable.

•Enter key – Display a submenu screen. NOTE: Availability of submenu screen is indicated by a (>).

•Esc – If you press this key:

•On one of the primary menu screens, the Exit menu displays.

•On a submenu screen, the previous screen displays.

•When you are making selections from a pop-up menu, closes the pop-up without making a selection.

•F1 – Display the General Help panel.

•F7 – Press to load user default values.

•F8 – Press to save user default values.

•F9 – Press to load optimized default system values.
