Central Processing Unit: CPU
The mainboard supports Intel® Pentium® 4 processor in the 478 pin
package. The mainboard uses a CPU socket called PGA478 for easy CPU
installation. When you are installing the CPU, make sure the CPU has a heat
sink and a cooling fan attached on the top to prevent overheating. If you do not
find the heat sink and cooling fan, contact your dealer to purchase and install
them before turning on the computer.

Hardware Setup
Memory
The mainboard provides 2 slots for 184-pin, 2.5V unbuffered DDR DIMM
with 4 memory banks. You can install PC1600/PC2100 DDR/PC2700 SDRAM
modules on the DDR DIMM slots (DDR 1~2). To operate properly, at least one
DIMM module must be installed.
DDR DIMM Slots
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but
doubles the rate by transferring data twice per cycle. It uses 2.5 volts as op-
posed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM modules
rather than 168-pin DIMM modules used by SDR SDRAM. Three types of
DDR SDRAM are available at the time of writing: PC1600, PC2100 and PC2700.
The following table shows the clock and peak bandwidth of each type of
DDR SDRAM module:

DDR Module Combination
You can install either single-sided or double-sided 184-pin DDR DIMM
modules into DDR DIMM slots to meet your needs. Different from the SDR
DIMM, the DDR DIMM has only one notch on the center of module. The
number of pins on either side of the breaks are different. The module will only
fit in the right orientation.
You can install memory modules in any combination as follows:

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:

slot and one CNR slot.
AGP Slot
PCI Slots
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 ac-
cess main memory and provides three levels of throughputs: 1x (266Mbps), 2x
(533Mbps) and 4x (1.07Gbps).
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.
PCI Interrupt Request Routing
The IRQ, abbreviation of interrupt request line and pronounced I-R-Q,
are hardware lines over which devices can send interrupt signals to the
microprocessor. The PCI IRQ pins are typically connected to the PCI bus INT

PnP/PCI Configurations
This section describes configuring the PCI bus system. PCI, or Peripheral
Component Interconnect, is a system which allows I/O devices to operate at
speeds nearing the speed the CPU itself uses when communicating with its
own special components. This section covers some very technical items and it
is strongly recommended that only experienced users should make any changes
to the default settings.
Reset Configuration Data
Normally, you leave this field Disabled. Select Enabled to reset Extended Sys-
tem Configuration Data (ESCD) when you exit Setup if you have installed a
new add-on and the system reconfiguration has caused such a serious conflict
that the operating system can not boot. The settings are: Enabled and Disabled.
Resource Controlled By
The Award Plug and Play BIOS has the capacity to automatically configure all
of the boot and Plug and Play compatible devices. However, this capability
means absolutely nothing unless you are using a Plug and Play operating
system such as Windows® 95/98. If you set this field to “manual” choose
specific resources by going into each of the sub menu that follows this field (a
sub menu is preceded by a “Ø”). The settings are: Auto (ESCD), Manual.
IRQ Resources
The items are adjustable only when Resources Controlled By is set to Manual.

PCI/VGAPaletteSnoop
When set to Enabled, multiple VGA devices operating on different buses can
handle data from the CPU on each set of palette registers on every video
device. Bit 5 of the command register in the PCI device configuration space is
the VGA Palette Snoop bit (0 is disabled). For example, if there are two VGA
devices in the computer (one PCI and one ISA) and the:
VGA Palette Snoop
Bit Setting
Action
Disabled
Enabled
Data read or written by the CPU is only directed to the PCI
VGA device’s palette registers.
Data read or written by the CPU is directed to both the PCI
VGA device’s palette registers and the ISA VGA device’s pal-
ette registers, permitting the palette registers of both VGA
devices to be identical.
The setting must be set to Enabled if any ISA bus adapter in the system
requires VGA palette snooping.

PC Health Status
This section shows the status of your CPU, fan, warning for overall system
status. Monitor function is available only if there is hardware monitoring
mechanism onboard.
CPU Warning Temperature
If the CPU temperature reaches the upper limit preset in this setting, the warn-
ing mechanism will be activated. This helps you to prevent the CPU overheat
problem.
Current System/CPU Temperature, CPU/System fan, Vcore, 3.3V, +5V, +12V,
-12V, -5V, VBAT(V), 5VSB(V)
These items display the current status of all of the monitored hardware de-
vices/components such as CPU voltages, temperatures and all fans’ speeds.

Frequency/Voltage Control
This section describes how to set the CPU FSB frequency, spread spectrum,
clock ratio etc.
CPU Clock Ratio
End users can overclock the processor by specifying the CPU ratio (clock
multiplier) in this field.
AutoDetectDIMM/PCIClk
This option allows you to enable/disable the feature of auto detecting the
clock frequency of the installed DIMM/PCI bus. The settings are: Enabled,
Disabled.
SpreadSpectrum
When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spec-
trum 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 overclocking be-
cause even a slight jitter can introduce a temporary boost in clockspeed which
may just cause your overclocked processor to lock up.

Set Supervisor/User Password
When you select this function, a message as below will appear on the screen:
Type the password, up to eight characters in length, and press <Enter>. The
password typed now will replace any previously set password from CMOS
memory. You will be prompted to confirm the password. Retype the password
and press <Enter>. You may also press <Esc> to abort the selection and not
enter a password.
To clear a set password, just press <Enter> when you are prompted to enter the
password. A message will show up confirming the password will be disabled.
Once the password is disabled, the system will boot and you can enter Setup
without entering any password.
When a password has been set, you will be prompted to enter it every time you
try to enter Setup. This prevents an unauthorized person from changing any
part of your system configuration.
Additionally, when a password is enabled, you can also have BIOS to request
a password each time the system is booted. This would prevent unauthorized
use of your computer. The setting to determine when the password prompt is
required is the Security Option of the Advanced BIOS Feature menu. If the
Security Option is set to System, the password is required both at boot and at
entry to Setup. If set to Setup, password prompt only occurs when you try to
enter Setup.
About Supervisor Password & User Password:
Supervisor password: Can enter and change the settings of
the setup menu.
User password:
Can only enter but do not have the right
to change the settings of the setup menu.
