Central Processing Unit: CPU
The VIA P4XB-MA mainboard supports the Intel® Pentium® 4 processor in the
478 pin package. When installing the CPU, make sure the CPU has a heat sink
and a cooling fan attached on the top to prevent overheating. If the heat sink
and cooling fan are not included with the CPU, contact your dealer to purchase
and install them before turning on the computer.
CPU Installation Procedures
1. Pull the lever sideways away
from the socket. Then raise the
lever up to a 90-degree
angle.
2. Look for the dot/cut edge. The
dot/cut edge should point towards the lever pivot. The
CPU will only fit in the correct
orientation.
3. Hold the CPU down firmly,
and then close the lever shut
to complete the installation.
WARNING!
Overheating will seriously damage the CPU and system.
Always make sure the cooling fan can work properly to
protect the CPU from overheating.

Hardware Setup
Installing the CPU Fan
To effectively dissipate heat generated by the CPU, you need to attach the
CPU cooling fan and heatsink on top of the CPU. Follow the instructions below
to install the Heatsink/Fan:
1. Locate the CPU and its retention

Overclocking
This motherboard is designed to support overclocking.
However, please make sure your components are able to
tolerate the abnormal settings required for overclocking.
Any attempt to operate beyond product specifications is not
recommended. We do not guarantee the damages or risks
caused by operation beyond product specifications.

Hardware Setup
Memory Installation
The mainboard provides two 184-pin DDR DIMM (2.5V) with 4 memory banks.
To operate properly, at least one DIMM module must be installed.
You can install two PC1600/PC2100 DDR SDRAM modules on the DDR DIMM
slots (DDR 1~2).
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but
doubles the rate by transfering data twice per cycle. It transfers data on both
the rising and falling edges of the clock. Conventional SDRAM only uses the
rising edge of the clock to transfer data.
DDR SDRAM uses 2.5 volts as opposed to 3.3 volts used in SDR SDRAM, and
requires 184-pin DIMM modules rather than 168-pin DIMM modules used by
SDR SDRAM.
Two types of DDR are available at the time of writing: PC1600 & PC2100.
PC1600 DDR SDRAM running at 100MHz will produce about 1.6GB/s memory
bandwidth. PC2100 running at 133MHz will produce 2.1GB/s memory bandwidth.

DDR Module Installation Procedures
You can install either single sided or double sided 184-pin DDR DIMM
modules into DDR DIMM slots, depending on your requirements. As opposed to SDR DIMMs, DDR DIMMs have only one notch in the center of
module. The modules will only fit if placed in the correct position.
You can install memory modules in any of the following combinations:

Jumpers
The mainboard provides one jumper for setting the computer’s functions. This
section will explain how to change your mainboard’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 mainboard provides three 32-bit Master PCI bus slots, one AGP 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 access
main memory and provides one level of throughput: 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 mainboards. Its
main processing is done through software and controlled by the motherboard’s
chipset.

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.
PNP OS Installed
When set to Yes, BIOS will only initialize the PnP cards used for booting (VGA,
IDE, SCSI). The rest of the cards will be initialized by the PnP operating system
like Windows® 95 or 98. When set to No, BIOS will initialize all the PnP cards.
So, select Yes if the operating system is Plug & Play aware.
Reset Configuration Data
Normally, you leave this field Disabled. Select Enabled to reset Extended System 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 “”). The settings are: Auto (ESCD), Manual.
IRQ Resources
The items are adjustable only when Resources Controlled By is set to Manual.
Press <Enter> and you will enter the sub-menu of the items. IRQ Resources list
IRQ 3/4/5/7/9/10/11/12/14/15 for users to set each IRQ a type depending on the
type of device using the IRQ. Settings are:
PCI Device
For Plug & Play compatible devices designed for PCI
bus architecture.
Reserved
The IRQ will be reserved for further request.
PCI/VGA Palette Snoop
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
Data read or written by the CPU is only directed to the PCI
VGA device’s palette registers.
Enabled
Data read or written by the CPU is directed to both the PCI
VGA device’s palette registers and the ISA VGA device’s palette 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.
Assign IRQ For VGA/USB/ACPI
The settings specify IRQ for each of the hardware components. Auto allows
BIOS to determine the IRQ automatically.

PC Health Status
This section displays the settings for monitoring the status of your CPU, fans,
and overall system status.
CPU Warning Temperature
If the CPU temperature reaches the upper limit preset in this setting, the warning mechanism will be activated. This helps you to prevent the CPU overheat
problem.
Current System, CPU Temperature/Current System, CPU Fan/Vcore/3.3V/
+5V/+12V/-12V/-5V/VBAT(V)/5VSB(V)
These items display the current status of all of the monitored hardware devices/components such as CPU voltages, temperatures and all fans’ speeds.

BIOS Setup
Frequency/Voltage Control
Auto Detect DIMM/PCI Clk
To reduce the occurrence of electromagnetic interference (EMI), the BIOS detects the presence or absence of components in DIMM and PCI slots and
turns off system clock generator pulses to empty slots. The settings are: Enabled, Disabled.
Spread Spectrum
When 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 overclocking because even a 0.25% jitter can introduce a temporary boost in clockspeed of
25MHz (with a 1GHz CPU) which may just cause your overclocked processor
to lock up.
CPU Clock
This setting specifies the clock frequency of CPU host bus (FSB) and provides
a method for end-users to overclock the processor accordingly.

CPU Ratio
This setting controls the multiplier that is used to determine the internal clock
speed of the processor relative to the external or motherboard clock speed.

BIOS Setup
Load Fail-Safe Defaults
This option allows users to restore all the BIOS settings to the default Fail-Safe
values. The Fail-Safe default settings are the settings set by the mainboard
manufacturer for stable running of the mainboard.
Pressing ‘Y’ loads the default Fail-Safe settings for stable system performance.

Chapter 3
Load Optimized Defaults
This option on the main menu allows users to restore all the BIOS settings to
the default Optimized values. The Optimized Defaults are the default values
also set by the mainboard manufacturer for both optimized and stable performance of the mainboard.
When you select Load Optimized Defaults, a message as below appears:
Pressing ‘Y’ loads the default values that are factory settings for optimal and
stable system performance.

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 clear any previously set password from CMOS
memory. You will be prompted to confirm the password. Re-type 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 Features menu. If the
Security Option is set to System, the password is required both at boot and at
