Hardware Setup

If your motherboard has already been installed in your computer you may still need to
refer to this chapter if you plan to upgrade your system's hardware.

This motherboard is electrostatic sensitive. Do not touch without
wearing proper safety gadget and make sure to disconnect the power
cable from the power source before performing any work on your
motherboard. Not doing so may result in electrical shock!

Installing a CPU processor in Socket 478

The Intel® Socket 478, designed for the Pentium 4 processor, has been incorporated
as a standard motherboard specification. To insert your CPU into Socket 478 please
follow the steps below

1. Locate the 478-pin CPU socket on the motherboard.

2. Unlock the socket by pressing the leaver sideways, and then open it up to a 90-degree

angle.

3. Locate a Gold Mark on the top surface of the CPU, which is close to one of the CPU

corners. The same corner will also be cut off, leaving a noticeable notch in the CPU's

corner. These markings indicate Pin 1 on the CPU.

4. Gently insert the CPU with Gold Mark/Pin 1 at the same corner of Socket 478, which is

located close to the end of the lever. Allow the weight of the CPU to push itself into

place. Do not apply extra pressure as doing so may result in damaging your CPU.

5. When the CPU is correctly inserted, close the leaver with your finger on to of the CPU

to make sure the CPU is properly embedded into the socket.

6. Insert an appropriate heat sink and fan for proper Heat dispatch.

Installing a standard Intel® specified heat sink with cooling fan is
necessary for proper heat dissipation from your CPU. Failing to install
these items may result in overheating and possible burnout of your CPU.

Main Memory Configuration

This motherboard provides two 184pin Double Data Rate (DDR) Dual-In-line
Memory Modules (DIMM) slots, which supports PC2100/2700/3200 DDR SDRAM
modules up to 2GB. Install at least one DIMM module on the slots. Memory modules
can be installed on the slots in any order. You can install either single- or
double-sided modules to meet your own needs.

Hardware Setup

5

To install your DDR Modules please follow these steps below:

1. Unlock a DIMM socket by pressing the retaining clips outward. The DDR Modules has

only one notch at the center of module. The DDR module will only fit in the right

position.

2. Insert the DDR Module vertically into the DIMM slot, with the correct alignment. Then

push it in until the golden finger on the memory module is deeply inserted into the

socket.

3. The plastic clip on each side of the DIMM slot will automatically close to hold the DDR

Modules in place.

Connector and Jumper Settings

Connectors are used to link the system board with other parts of the system, including
the power supply, the keyboard, and the various controllers on the front panel of the
system case.

The power supply connector is the last connection to be made while
installing a motherboard. Before connecting the power supply, please
make sure it is not connected to the power source.

All cables come with a security-proof.

Hardware Setup

PW 1/3

The power cord leading from the system's power supply to the external power source
must be the very last part connected when assembling a system. The ATX power
supply provides a single 20-pin connector interface, which incorporates standard
+/-5V, +/-12V, optional 3.3V and Soft-power signals. The Soft power signal, a 5V
trickle supply is continuously supplied when AC power is available. When the system
is in the Soft-Off mode, this trickle supply maintains the system in its minimum
power state. The ATX 12V power supply has a new +12V (4-pin) and +5V/3.3V
(6-pin) auxiliary power connector to enable the delivery of more +12 VDC and
+5/3.3V VDC current to the motherboard.

1. PWR-SW (Over-ride Power Button Connector)

The power button on the ATX chassis can be used as a normal power switch as well
as a device to activate Advanced Power Management Suspend mode. This mode is
used for saving electricity when the computer is not in use for long periods of time.
The Soft-OFF by PWR-BTTN function in BIOS's Power Management Setup menu
must be set to [Delay 4 Sec.] to activate this function.
When the Soft-OFF by PWR-BTTN function is enabled, pushing the power button
rapidly will switch the system to Suspend mode. Any occurrence of external
activities such as pressing a key on the keyboard or moving the mouse will bring the
system back to Full-On. Pushing the button while in Full-On mode for more than [4
seconds] will switch the system completely off. See Over-ride Power Button
Operation diagram.

2. P-LED (Power LED Connector)

The power indicator LED shows the system's power status. It is important to pay
attention to the correct cable and pin orientation (i.e. Be careful not to reverse the

Hardware Setup

order of these two connectors.)

3. G-BTN/G-LED (Green Button Switch/LED Connector)

Some ATX cases provide a Green button switch, which is used to put the system in
Suspend mode. In Suspend mode, the power supply to the system is reduced to a
trickle, the CPU clock is stopped, and the CPU core is in its minimum power state.
The system is activated whenever the keyboard or mouse is touched. The system
resumes in various ways as defined by Power Management Setup screen in BIOS.

4. RESET (System Reset Switch Connector)

This connector should be connected to the reset switch on the front panel of the
system case. The reset switch allows you to restart the system without turning the
power off.

5. SPEAKER (Speaker Connector)

This 4-pin connector connects to the case-mounted speaker.

BIOS Setup Program

Phoenix-Award BIOS ROM has a built-in setup program that allows users to modify
the basic system configuration. This information is stored in CMOS RAM so that it
can retain the setup information even when the power is turned off.
To enter the Phoenix-Award BIOS setup program:
Press Delete when you Power on or Reboot the computer system. (i.e. After the
Intel Pentium 4 logo appears at the center of the screen, please press Delete to enter
the BIOS setup program).
The primary screen as shown in the following Figure is a list of the menus and
functions available in the setup program. Select the desired item by using arrow keys
and press Enter to make the changes. Operating commands are located at the bottom
of this and all other BIOS screens. When a field is highlighted, on-line help
information is displayed on the right side of the screen.

Standard CMOS Setup

The Standard CMOS Setup allows users to configure system components such as hard
disk drive, floppy disk drive and video display as well as date, time and boot-up error
signaling. This configuration menu should be changed when installing a motherboard
for the first time, or changing hardware such as the HDD, FDD, and video display in
your system, or when the CMOS data is lost or corrupted. Choose the Standard
CMOS Setup option from the CMOS Setup Utility menu (Figure 3-1) to display the
following screen.

BIOS Setup Program

15

Date/Time

Set the date and time of the system. Do not skip this function as all of your timed
events such as power management, saving files, etc are based on this timer.

IDE (Channel 0/1/2/3; Master/Slave)

This category identifies up to IDE hard disk drives that have been installed in the
computer. This section does not show information on other IDE devices such as
CD-ROM drives or other hard drive type such as SCSI drives.

Drive A/B

Select different Floppy device Model. Available options are [None], [360K, 5-1/4 in],
[1.2M, 5-1/4 in], [720k, 3-1/2 in], [1.44M, 3-1/2 in], and [2.88M, 3-1/2 in].

Video

Select the type of video adapter present in your system. You can ignore this setting if
you are using a VGA monitor; VGA BIOS will automatically configure this setting.

Halt On

When the system is powered on, BIOS performs a series of diagnostic tests called
POST (Power On Self Test). This function stops the computer if BIOS detects a
hardware error. You can tell BIOS to halt on all errors, no errors, or not to halt on
specific errors.

Advanced BIOS Features
Hard Disk Boot Priority

Select priority of the hard disk boot device.

Virus Warning

Allows you to choose the VIRUS warning feature for IDE Hard Disk boot sector
protection. If this function is enabled and someone attempts to write data into this area.
BIOS will show a warning message on screen and alarm beep.

CPU L1 & L2 Cache

Cache memory is much faster than conventional DRAM system memory. These fields
allow you to enable or disable the CPUs Level 1 built-in cache and Level 2 external
cache. Both settings are left as Enabled to significantly increase the performance of
your computer.

CPU L2 Cache ECC Checking

Enable this function for the CPU L2 Cache Error Checking and Correcting (ECC)
operation.

BIOS Setup Program

16

Quick Power On Self Test

Enable this function to reduce the amount of time required to run the POST (Power
On Self Test). BIOS will save time by skipping some items during POST. It is
recommended that you disable this setting. Discovering a problem during boot up is
better than loosing data during your work.

First/Second/Third/Boot Other Device

These options set the order of drives BIOS attempts to boot from.

Swap Floppy Drive

Enabling this function will swap the floppy drive assignment so that drive A will
function as drive B, and drive B will function as drive A. Note that the boot sequence
assignment mentioned directly above does not include booting from floppy drive B.
This function is useful if floppy drives B and A are of a different format and you want
to boot from floppy drive B.

Boot up Floppy Seek

This is a set up check for floppy power-on after starting the computer system.

Boot Up NumLock Status

This function defines the keyboard's number pad as number keys or arrow keys. If it is
set at On the number keys will be activated, if it is set at Off the arrow keys will be
activated.

Typematic Rate Setting

When enabled, you can set the following two-typematic control items. When disabled,
the keyboard controller determines keystrokes arbitrarily in your system.

Typematic Rate (Chars/Sec)

The typematic rate sets the rate at which characters on the screen repeat when a key is
pressed and held down.

Typematic Delay (Msec)

The typematic delay sets how long after you press a key that a character begins
repeating.

Security Option

The Supervisor and/or User Password functions shown in Figure 3-1 must be set to
take advantage of this function. See Section 3.12 for password setting information.
When the Security Option is set to System, a password must be entered to boot up the
system or enter the BIOS setup program. When the Security Option is set to Setup, a
password is required to enter the BIOS setup program.

BIOS Setup Program

17

APIC Mode
This item can enable or disable the APIC (Advanced Programmable Interrupt
Controller). Due to compliance to PC2001 design guide, the system is able to run in

APIC mode. Enabling APIC mode will expand available IRQs resources for the
system. Available options are Enabled and Disabled.

MPS Version Control For OS

This item allows you to select which MPS (Multi-Processor Specification) version
to be used for the operating system. You need to select the MPS version that is
supported by your operating system. To find out which version to use, consult the
vendor of your operating system. Available options are [1.4] and [1.1].

OS Select For DRAM >64MB

If your system's DRAM is larger than 64MB and you are running OS/2, select OS/2 as
the item value. Otherwise, set the item value to Non-OS/2 for all other operating
systems.

Advanced Chipset Features
DRAM Clock/Drive Control

Press Enter to enter the submenu.

DRAM Clock

There will be five options for the DRAM Clock settings. They are By SPD, 100MHz,
133MHz, 166MHz and 200MHz. The first is strongly recommended.

DRAM Timing

The function allows you to enable or disable the DRAM timing by SPD. It is
recommended to keep the default setting for a stable system operation.

SDRAM CAS Latency

CAS is short for column address strobe, which is a kind of signals. When the CPU
needs data from SDRAM, CAS signals will be sent via the CAS line to specify the
column where the data is needed. This controls the time delay (in clock cycles - CLKs)
that passes before the SDRAM starts to carry out a read command after receiving it.
This also determines the number of CLKs for the completion of the first part of a
burst transfer. In other words, the lower the latency, the faster the transaction.
Note that some SDRAM modules may not be able to handle the lower latency and
will become unstable and lose data. Therefore, set the DRAM CAS Latency Time to 2
for optimal performance if possible but increase it to 2.5 if your system becomes
unstable.
Interestingly, increasing the CAS latency time does have an advantage in that it will
enable the SDRAM to run at a higher clockspeed, thereby giving you an edge in

BIOS Setup Program

18

overclocking your system. So, if you hit a snag while overclocking, try increasing the
CAS latency time.

Bank Interleave

This feature enables you to set the interleave mode of the DRAM interface.
Interleaving allows banks of SDRAM to alternate their refresh and access cycles. One
bank will undergo its refresh cycle while another is being accessed. This improves
performance of the SDRAM by masking the refresh time of each bank. A closer
examination of interleaving will reveal that since the refresh cycles of all the SDRAM
banks are staggered, this produces a kind of pipelining effect. Whether you set this
option to 2-bank or 4-bank is determined by the type of SDRAM you have and how
many banks are on your DIMMs. Most SDRAM in use today (sticks 64 MB of higher)
are 4-bank, so setting this option to 4-bank is usually right. If you are unsure, you can
look up the specs of your SDRAM. Otherwise, just disable the option.

Precharge to Active (Trp)

Setup the minimum row precharge time.
The Choice: 2T, 3T, 4T and 5T.

Active to Precharge (Tras)

Setup the minimum RAS pulsewidth.
The Choice: 6T, 7T, 8T and 9T.

Active to CMD (Trcd)

Setup the minimum CAS to RAS delay.
The Choice: 2T, 3T, 4T and 5T.

REF to ACT/REF to REF (Trfc)

Refresh row cycle time.
The Choice: 12T, 13T, 14T and 15T.

ACT (0) to ACT(1) (TRRD)

The Choice: 2T and 3T.

DRAM BUS Selection

Allows the user to force the system to access the memory in Single or Dual Channel
mode.
The Choice: Auto, Single Channel and Dual Channel.

DRAM Command Rate

Setup the timing at each cycle.
The Choice: 1T Command, 2T Command.

AGP & P2P Bridge Control

Press Enter to see what this contains.

AGP Aperture Size

This function determines the amount of system memory that is given to the AGP card.

BIOS Setup Program

19

Available options ranges from 32MB to 256MB. This is a dynamic memory allocation
in that the AGP card will only use the amount of memory that it needs. The remaining
unused memory is also available for system usage.

AGP 2.0 Mode

Allows you to control the type of AGP used: 1X, 2X, and 4X, depending on the specs
supported by your motherboard. Set it to the highest your video card will support.

AGP Driving Control

Enables or disables the use of the following setting. Called AGP Comp. Driver in
AMIBIOS. See next option.

AGP Driving Value

A feature of Via chipsets that allows manual control over the strength/timing of the
AGP signal to the video card. It is more or less a workaround by Via to accommodate
some areas of AGP that it is just not as good at as Intel. On 1X and 2X AGP cards,
this is a non-issue. With higher-speed cards, it can become an issue. The available
values are in hex format. Usually, this is left set to AUTO. If you need to use it to
make your video card stable, the best bet is to contact the manufacturer to see what
they recommend for a driver value.

AGP Fast Write

Allows data to be sent directly from the corelogic (i.e. chipset) to the AGP master
(graphics chip) instead of keeping a copy in system memory and making the AGP
master fetch it. Can be enabled on 4X and higher cards for better performance.

AGP Master 1 WS Write/Read

When enabled, writes/reads to the AGP port are executed with one wait state. Usually,
two are used, although some motherboards come with no wait states used, in which
case this setting can hinder performance.

AGP 3.0 Calibration cycle

Available options: disabled, enabled.

CPU & PCI Bus Control

PCI Master O WS Write

Controls whether writes to the PCI bus are done with zero wait states or not. Enabled
by default on many boards.

PCI Delay Transaction

The chipset has an embedded 32-bit posted write buffer to support delay transactions
cycles. Select Enabled to support compliance with PCI specification version 2.1.

Memory Hole

An old feature that allowed you to set off 1 MB of memory for use by an ISA card.
Most ISA cards, if you can still find them, don't use this anyway.

BIOS Setup Program

20

System BIOS Cacheable

Enabling this function allows caching of the system BIOS ROM at F0000h-FFFFFh,
which results in better system performance. However, if any program writes to this
memory area, a system error may result. It is advisable to leave it in default setting.
Caching the system BIOS results in better performance than shadowing the system
BIOS.

Init Display First

This function allows users to choose between AGP or PCI Slot to initialize Display
first.

Flash BIOS Protection

The motherboard manufacturer developed BIOS protection technology that protects
the System BIOS from accidental corruption by unauthorized users or computer
viruses. When enabled, the BIOS data cannot be changed when attempting to update
BIOS with the FLASH utility. When disabled, the BIOS data can be updated by using
the FLASH utility.

Power Management Setup
ACPI Suspend Type

This feature allows user to select a suspend type for the operating system to turn off
peripherals devices, such as CD-ROM players, when they are not in use.

Power Management Option

Power management allows the computer to save electricity when it is idle by entering
power saving modes.

HDD Power Down

Shuts down any IDE hard disk drives in the system after a period of inactivity as set in
this user configurable field. This feature does not affect SCSI hard drives.

Video Off Option

This setting allows you to select the power-saving modes during which the monitor
goes blank.

Video Off Method

This function serves as both a screen saver and power saver for monitors. See the next
function, Video Off After, for setting the video timer.
l Blank - BIOS will only blank the monitor's screen. The electricity saved in this

mode is negligible and this function is only used as a screen saver to prevent
screen damage while the screen is on but not in use.

l V/H SYNC+Blank - The system turns off the vertical and horizontal

synchronization ports, writes blanks to the VGA buffer and the monitor's electron
gun turns off. This function requires a monitor with Green features in order to
take advantage of the power saving function. If you enable this function and do
not have a Green monitor, the result will be the same as if you had selected
Blank. This function serves as both a screen saver and a power saver.

l DPMS Supported - Select this option if your video card supports the Display

Power Management Signaling (DPMS) standard (i.e., you have a monitor that
supports Green features). Use software supplied by your video subsystem to set
video power management options.

MODEM Use IRQ

If your computer has a modem use this function to tell BIOS which IRQ is being
occupied by the modem card. When the system is in Green mode, the modem requires
an IRQ assignment to wake up the system and perform tasks. This is compliant with
APM 1.2 operating systems.

Soft-Off by PWRBTN

When set to Delay 4 Sec., this function allows the power button to put the system in
Suspend, a power saving mode. When set to Instant-Off the Soft-Off by PWR-BTN
function is disabled and the computer turns completely off when the power button is
pressed.

PCI Master

This options control the activation of PCI slots. Available options: On, Off.

PowerOn by PME/Onboard LAN

When enabled, the nVidia LAN, which is on Board, will be able to receive a signal
and wake up the system from soft off and suspend mode. You should connect the
LAN to the RJ45 port and turn on the resume event in suspend mode.

PowerOn by Ring/WOL

When enabled, a Modem/LAN will be able to receive a signal and activate the system
from soft off and green mode. You should connect the modem to the COM port and
signal your PC to power on.

RTC Alarm Resume

When enabled, this setting allows the system to turn back on at a designated time of
the month. User must designate date of month and time of day. This function is only
available when using an ATX power supply and the Software Power-Off function to

turn off the computer.

IRQs Activity Monitoring

This feature allows you to monitor a list of IRQ, Interrupt ReQuests. When an I/O
device wants to gain the attention of the operating system, it signals this by causing an
IRQ to occur. When the operating system is ready to respond to the request, it
interrupts itself and performs the service.

PnP/PCI Configurations
PnP OS Installed

If all your operating systems support Plug & Play (PnP), select Yes so that they can
take over the management of device resources. If you are using a non-PnP-aware OS
or not all of the operating systems you are using support PnP, select No to let the
BIOS handle it instead. Some say that it is best to leave this option set to No
regardless of whether your OS is PNP-capable or not. The reason is that when it is set
to No, the BIOS will attempt to resolve any resource conflicts. If it is set to Yes, even
if a conflice is detected, the BIOS will ignore it. So, setting it to Yes provide a bit of a
safety net, and it will not affect the ability of the OS to perform PNP on its own.

Reset Configuration Data

ESCD (Extended System Configuration Data) is a feature of the Plug & Play BIOS
that stores the IRQ, DMA, I/O and memory configurations of all the ISA, PCI and
AGP cards in the system (PnP or otherwise). Normally, you should leave the setting as
Disabled. If you encounter serious problems with the installation of a new PCI card,
this settings can help bail you out. Such a conflict would be serious enough that the
OS may not start. If this happens, you can go into the BIOS and enable this option.
Next time the PC boots, the BIOS will go and re-configure the settings for all PNP
cards. The BIOS will automatically reset this setting to DISABLED next time you
boot.

Resources Controlled By

When set to Manual the system BIOS will not refer to the ESCD for IRQ & DMA
information. Instead, it will refer to the items in the setup menu for assigning IRQ &
DMA. When set to Auto the system BIOS will refer to the ESCD for all legacy
information. ESCD (Extended System Configuration Data) provides a detailed
format of the configuration data structures stored in flash memory. Each data structure
defines the resources used by a device or a card in the system. This includes legacy
and PCI/ISA PnP devices.

PCI/VGA Palette Snoop

This option is only useful if you use an MPEG card or an add-on card that makes use
of the graphics card's Feature Connector. It corrects incorrect colour reproduction by
"snooping" into the graphics card's framebuffer memory and modifying
(synchronizing) the information delivered from the graphics card's Feature Connector
to the MPEG or add-on card. It will also solve the problem of display inversion to a
black screen after using the MPEG card.

Assign IRQ For VGA

Many high-end graphics accelerator cards now require an IRQ to function properly.
Disabling this feature with such cards will cause improper operation and/or poor
performance. Thus, it's best to make sure you enable this feature if you are having
problems with your graphics accelerator card.

Assign IRQ For USB

Assigns an IRQ to the USB controller. It enables or disables IRQ allocation for the
USB (Universal Serial Bus). If you are using AGP, this shoudl be enabled. If you are
not, you can disable this to free up an IRQ.

FDD IRQ Can Be Free

This function allows user to choose if the FDD IRQ can be freed up. The default
setting is Yes and this does not allow the IRQ to be free.

Frequency/Voltage Control
CPU Clock Ratio

The BIOS will autodetect the processor speed and set it accordingly.

Auto Detect PCI Clk

This BIOS feature determines whether the BIOS should actively reduce EMI
(Electromagnetic Interference) and reduce power consumption by turning off
unoccupied or inactive expansion slots.
When enabled, the BIOS will monitor PCI slots and turn off clock signals to all
unoccupied and inactive slots.
When disabled, the BIOS will not monitor PCI slots. All clock signals will remain
active even to unoccupied or inactive slots.
It is recommended that you enable this feature to save power and reduce EMI.

Spread Spectrum

Displays the default value as Enabled.

Load Fail-Safe Defaults

To avoid errors, this option allows you to recover the original defaults of BIOS. In
fact, this is the first skill you should know when you try to set other defaults of BIOS.

Load Optimized Defaults

This option has the similar function to the previous one. The difference between them
is that the first is more efficient in settings, and this has the disadvantage of
potentially making the system unstable. So, the decision is up to you.

Supervisor Password

There are four different variables that control password settings. The first two are
located under the Security Option function in BIOS Features Setup Menu (Figure 3-1).
When the Security Option function is set to Setup, a password is required to enter
BIOS and change BIOS settings. When the Security Option function is set to
System, a password is required to enter both BIOS and computer's operating system
(For example, Windows 98) found on the boot drive.
The third and fourth variables are user password and supervisor password selected in
BIOS (Figure 3-1). The main purpose of separating users and supervisors is to allow
only the supervisor to have control over the BIOS settings. The user, on the other hand,
is only allowed to access computer's operating system and change the user password
in BIOS.
