Chapter 2 13Phoenix TrustedCore Setup UtilityPhoenix TrustedCore Setup Utility is a hardware configuration program built into your system's Basic Input/Output System (BIOS). Since most systems are already properly configured and optimized, there is normallyno need to run this utility.You will need to run this utility under the following conditions:T When changing the system configuration including:t Setting the system time and datet Configuring the hard drivest Specifying the boot device sequencet Configuring the power management modest Setting up system passwords or making other changes to the security setupT When a configuration error is detected by the system and you are prompted (“Run Setup” message) tomake changes to the BIOS settings.IMPORTANT: If you repeatedly receive “Run Setup” messages, the RTC battery located on the systemboard (RTC1) may be defective. In this case, the system cannot retain configuration values inCMOS. 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 “SetupUtility” in this Service Guide.The screenshots used in this guide display default system values. These values may not be the sameas those in your computer.In the descriptive tables following each of the menu screen illustrations, settings in boldface are thedefault 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 isturned off. The values take effect when the system is booted. Power-On Self Test (POST) uses these values toconfigure the hardware. If the values and the actual hardware do not agree, POST generates an errormessage. You must run this utility to change the BIOS settings from the default or current configuration.System UtilitiesChapter 2
