Phoenix TrustedCore Setup Utility
 Phoenix TrustedCore Setup Utility is a hardware configuration program built into your systems Basic Input/
Output System (BIOS). Since most systems are already properly configured and optimized, there is normally 
no need to run this utility. 
You will need to run this utility under the following conditions: 
TWhen changing the system configuration including: 
t     Setting the system time and date
t     Configuring the hard drives
t     Specifying the boot device sequence
t     Configuring the power management modes
t     Setting up system passwords or making other changes to the security setup
TWhen a configuration error is detected by the system and you are prompted (“Run Setup” message) to 
make changes to the BIOS settings. 
IMPORTANT:   If you repeatedly receive “Run Setup” messages, the RTC battery located on the  system 
board (RTC1) may be defective. In this case, the system cannot retain configuration values in 
CMOS. Replace the RTC battery with a new one.
NOTE:   For ease of reading, Phoenix TrustedCore Setup Utility will be simply referred to as “Setup” or “Setup 
Utility” in this Service Guide.
The screenshots used in this guide display default system values. These values may not be the same 
as those in your computer. 
In the descriptive tables following each of the menu screen illustrations, settings in boldface are the 
default and suggested parameter settings.
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. Power-On Self Test (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.
