System Utilities
Phoenix TrustedCore Setup Utility
Phoenix 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 normally no need to run this utility. You will need to run this utility under the following conditions: When changing the system configuration including:
Setting the system time and date Configuring the hard drives Specifying the boot device sequence Configuring the power management modes Setting up system passwords 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 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.

Chapter 4
POST Error Indicators
When POST detects a system failure, it either displays a POST error message, or emits a series of beep codes.
POST Error Message
Whenever a non-fatal error occurs during POST, an error message describing the problem appears onscreen. These text messages are displayed in normal video (white text on black background). It shows the details of the error. The POST error message index in this section lists the error messages and their possible causes. The most likely cause is listed first. The listed error symptoms classified by function. NOTE: Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU replacement does not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU. This index can also help you determine the next possible FRU to be replaced when servicing a computer. If the symptom is not listed, see "Undetermined Problems" on page 81. NOTE: Most of the error messages occur during POST. Some of them display information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the way it has been configured. IMPORTANT: If the system fails after you make changes in the Setup Utility menus, reboot the computer, enter Setup, then press F9 to load the Setup defaults to correct the error.
