Chapter 2 System Utilities Most systems are already configured by the manufacturer or the dealer. There is no need to ru Setup when starting the computer unless you get a Run Setup message. The Setup program loads configuration values into the battery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM. NOTE: If you repeatedly receive Run Setup messages, the battery may be bad. In this case, the system cannot retain configuration values in CMOS.
Entering Setup To enter Setup, press the key combination NOTE: You must press b+a+^ during the POST (Power-on self-test). b+a+^ simultaneously while the system is booting. The Setup Utility main menu then appears: The above screen is the BIOS Utility Basic Level screen. It allows you to view and change only the basic configuration of your system. The command line at the bottom of the menu tells you how to move within a screen and from one screen to another.
Product Information The screen below appears if you select Product Information from the main menu: The Product Information menu contains general data about the system, such as the product name, serial number, BIOS version, etc. These information is necessary for troubleshooting (maybe required when asking for technical support).

Integrated Peripherals The following table describes each Integrated Peripherals parameter. Settings in boldface are the default and suggested settings. Parameter On-Chip Primary PCI IDE On-Chip Secondary PCI IDE IDE Primary Master PIO IDE Primary Slave PIO IDE Secondary Master PIO IDE Secondary Slave PIO Description Options These parameters let you enable or disable the IDE devices connected to the primary and secondary IDE connectors.
Parameter Description Options USB Keyboard Support This item lets you enable or disable the USB keyboard driver within the onboard BIOS. The keyboard drive simulates legacy keyboard command and lets you use a USB keyboard during POST or after boot if you don’t have a USB driver in the operating system. Enabled Disabled USB Mouse Support This item lets you enable or disable the USB mouse driver within the onboard BIOS.
Parameter Description Midi Port Address Selects the Midi Port Address. Midi Port IRQ Selects the Midi Port IRQ.
Power Management Setup The Power Management menu lets you configure the system power-management feature. It works only in APM mode.

POST Error Messages List If you cannot run the diagnostics program tests but did receive a POST error message, use “POST Error Messages List” to diagnose system problems. If you did not receive any error message, look for a description of your error symptoms in “Error Symptoms List” on page 73 . NOTE: When you have deemed it necessary to replace an FRU, and have done so, you must run a total system check to ensure that no other activity has been affected by the change.
BIOS Messages Action/FRU Memory Size Has Changed Since Last Boot In EISA mode, use Configuration Utility to reconfigure the memory configuration. In ISA mode, enter Setup and enter the new memory size in the memory fields. Memory Verify Error Use this location along with your system’s memory map to locate hte bad chip. Offending Address Not Found This message is used in conjunction with the I/O CHANNEL CHECK and RAM PARITY ERROR messages when the segment that has caused problem cannot be isolated.
Error Symptoms List NOTE: To diagnose a problem, first find the error symptom in the left column. If directed to a check procedure, replace the FRU indicated in the check procedure. If no check procedure is indicated, the first Action/ FRU listed in right column is the most likely cause.

For the External Modem, make sure Power on By Ring in BIOS Setup or Power Management is set to Enabled. For the PCI modem, make sure Wake up by PCI card is set to Enabled. 2. If PCI modem card is used, reinsert the modem card to PCI slot firmly or replace the modem card. 3.
Error Symptom Action/FRU Parallel/Serial Ports Execute “Load BIOS Default Settings” in BIOS Setup to confirm ports presence before diagnosing any parallel/serial ports problems. Serial or parallel port loop-back test failed. 1. Make sure that the LPT# or COM# you test is the same as the setting in BIOS Setup. 2. Loop-back. 3. Main board. Printing failed. 1. Ensure the printer driver is properly installed. Refer to the printer service manual. 2. Printer. 3. Printer cable. 4. Main board.
Undetermined Problems If an error message is present, go to “POST Error Messages List” on page 71. If you did not receive any messages, if the symptom is listed in “or “Error Symptoms List” on page 73 . If you still cannot solve the problem, continue with this check: 1. Check the power supply voltages. If the voltages are correct continue with the following steps: 2. Power off the system unit. 3.
