System Utilities
Most systems are already configured by the manufacturer or the dealer. There is no need to run
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/flat. In this case, the system
cannot retain configuration values in CMOS.
Before you run Setup, make sure that you have saved all open files. The system reboots immediately after
you exit Setup.
Chapter 224
Page 31
Entering Setup
Power on the computer abd the system will start POST (Power On Self Test)prosecc. When the message of
“Press DEL to enter SETUP” appears on the screen, press the key of [Delete] to enter the setup menu.
NOTE: If the message disappears before you respond and you still wish to enter Setup, restart the system by
turning it OFF and On. You may also restart the system by simultaneously pressing [Ctrl+Alt+Delete].
The Setup Utility main menu then appears:

The command line at the bottom of the menu tells you how to move within a screen and from one screen to
another.
TTo select an option, move the highlight bar by pressing or then press .
TTo change a parameter setting, press or until the desired setting is found.
TPress to return to the main menu. If you are already in the main menu, press again to
exit Setup.
The parameters on the screens show default values. These values may not be the same as those in your
system.
The grayed items on the screens have fixed settings and are not user-configurable.
NOTE: Due to the application of a new version of BIOS Setup program, you may find the BIOS menu is largely
different from the former models. However, you will soon find out that this version is much more
compact than the former ones.

extended memory.
Extended MemoryMemory above and beyond the standard 1MB of
base memory that DOS supports. Extended
memory is only available in PCs with an Intel
80286 or later microprocessor. Extended
memory is not configured in any special manner
and is therefore unavailable to most DOS
programs. However, MS Windows and OS/2
can use extended memory.

The following table describes the parameters found in this menu. Settings in boldface are the default and
suggested settings.
ParameterDescriptionOptions
Set CPU RatioEnd users can overlock the processor by
specifying the CPU ratio (clock multiplier) in this
field.
CPU Clock RatioIf the CPU Ratio is set to Manual, end users can
choose a suitable ratioto support the CPU.
Auto Detect DIMM/PCI ClkThis option allows you to enable/disable the
feature of auto detecting the clock frequency of
the installed DIMM/PCI bus.
Spread SpectrumWhen the motherboard’s clock generator pulses,
the extreme values (spikes) of the pulses creates
EMI (Electromagnetic Interference). The spread
Spectrum function reduces the EMI generated by
modulating the pulses so that the spikes of the
pulses are reduced to flatter curves. If you do
not have any EMI problem, leave the setting at
Disabled for optimal system stability and
performance. But if you are plagued by EMI,
setting to Enabled for EMI reduction. Remember
to disable Spread Spectrum if you are
overlocking because even a slight jitter can
introduce a temporary boost in clockspeed which
may just cause your overlock ed processor to
lock up.

Chapter 462
Page 69
Power-On Self-Test (POST)
Each time you turn on the system, the Power-on Self Test (POST) is initiated. Several items are tested during
POST, but is for the most part transparent to the user.
The Power-On Self Test (POST) is a BIOS procedure that boots the system, initializes and diagnoses the
system components, and controls the operation of the power-on password option. If POST discovers errors in
system operations at power-on, it displays error messages on screen, generates a check point code at port
80h or even halts the system if the error is fatal.
The main components on the main board that must be diagnosed and/or initialized by POST to ensure system
functionality are as follows:
TMicroprocessor with built-in numeric co-processor and cache memory subsystem
TInterrupt system (8259 module) or APIC (advance program interrupt controller)
TThree programmable timers (system timer and 8254 module)
TROM subsystem
TRAM subsystem
TCMOS RAM subsystem and real time clock/calendar with battery backup
TOnboard serial interface controller
TOnboard parallel interface controller
TEmbedded hard disk interface and one diskette drive interface
TKeyboard and auxiliary device controllers
T I/O ports
TTwo RS232 serial ports
TOne parallel port
TOne PS/2-compatible mouse port
TOnePS/2-compatible keyboard port
NOTE: When Post executes a task, it uses a series of preset numbers called check points to be latched at
port 80h, indicating the stages it is currently running. This latch can be read and shown on a debug board.
The following table describes the BIOS common tasks carried out by POST. Each task is denoted by an
unique check point number. For other unique check point numbers that are not listed in the table, refer to the
correspoing product service guide.
Post Checkpoints List: The list may vary accordingly depending on your BIOS.

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 71.
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. This system check can
be done through the diagnostics program.
NOTE: Check all power supply voltages, switch, and jumper settings before you replace the main board. Also
check the power supply voltages if you have a “system no-power” condition.
If you are unable to correct the problem by using the “BIOS Messages List” table and “Error Symptoms List”
table, go to “Undetermined Problems” on page 75.
NOTE: To diagnose a problem, first find the BIOS error messages 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.

Jumpers
The motherboard provides one jumper for you to set the computer’s
function. This section will explain how to change your motherboard’s function
through the use of the jumper.
Clear CMOS Jumper: JBAT1
There is a CMOS RAM on board that has a power supply from external
battery to keep the data of system configuration. With the CMOS RAM, the
system can automatically boot OS every time it is turned on. That battery has
long life time for at least 5 years. If you want to clear the system configuration,
use the JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions
below to clear the data:

Slots
The motherboard provides three 32-bit Master PCI bus slots, one AGP
slot and one CNR slot.
AGP Slot
PCI S lots
CNR Slot
AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert the AGP graphics card. AGP is an
interface specification designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-bit channel for the graphics controller to directly
access main memory. The slot only supports 4x AGP card.
PCI Slots
Three PCI slots allow you to insert the expansion cards to meet your
needs. When adding or removing expansion cards, make sure that you unplug
the power supply first. Meanwhile, read the documentation for the expansion
card to make any necessary hardware or software settings for the expansion
card, such as jumpers, switches or BIOS configuration.
CNR (Communication Network Riser)
The CNR slot allows you to insert the CNR expansion cards. CNR is a
specially designed network, audio, or modem riser card for ATX family
motherboards. Its main processing is done through software and controlled by
the motherboard’s chipset.
