Central Processing Unit: CPU

The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™
processors in the 462 pin package. The mainboard uses a CPU socket called
Socket A 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.

1. Pull the lever sideways away

from the socket. Then, raise
the lever up to a 90-degree
angle.

2. Look for the cut edge. The

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 to com­plete the installation.

CPU Installation Procedures

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

2-3

As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly crucial when building computer
systems. Maintaining the proper thermal environment is key to reliable
operation. As such, the processor must be maintained in the specified thermal
requirements.

AMD Athlon™/Duron™/Athlon™ XP processor with a speed of 600MHz
and above requires LARGER heatsink and fan. You also need to add thermal
grease between the CPU and heatsink to improve heat dissipation. Then, make
sure that the CPU and heatsink are securely fastened and in good contact with
each other. These are needed to prevent damaging the processor and ensur­ing reliable operation. If you want to get more information on the proper
cooling, you can visit AMD’ s website for reference.

WARNING! Thermal Issue for CPU

Chapter 2

2-4

CPU Core Speed Derivation Procedure

If CPU Clock = 100MHz

Core/Bus ratio = 7

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 7
= 700MHz

Overclocking

This motherboard is designed to support overclocking.
However, please make sure your components are able to
tolerate such abnormal setting, while doing overclocking.
Any attempt to operate beyond product specifications is
not recommended. We do not guarantee the damages or

risks caused by inadequate operation or beyond product
specifications.

WARNING!

CPU Clock Selection

The hardware configuration for CPU Front Side Bus (FSB) frequency on
the motherboard is set to 100MHz by default. Therefore, to enable a 133MHz
CPU to run at 133MHz when it is installed on the board, you have to adjust the
CPU clock frequency through the jumper SW1.

For more information on the issue, refer to CPU FSB Clock Jumper: SW1
later in this chapter.

Hardware Setup

2-5

The mainboard provides 2 sockets for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) modules and supports the memory size up
to 2GB. Y ou can install PC2100/DDR266 or PC1600/DDR200 DRAM modules
on the DDR DIMM slots (DIMM 1~2).

Memory

DDR DIMM Slots

(DIMM 1~2)

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
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. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta­tions and servers.

Chapter 2

2-6

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 double­sided modules to meet your own needs.

Memory modules can be installed in any combination as follows:

Slot Memory Module Total Memory

DIMM 1
(Bank 0 & 1)

S/D 64MB~1GB

DIMM 2

The motherboard provides the following jumpers for you to set the
computer’s function. This section will explain how to change your
motherboard’s function through the use of the jumpers.

You can clear CMOS by shorting 2-3 pin while the
system is off. Then return to 1-2 pin position. Avoid
clearing the CMOS while the system is on; it will dam­age the mainboard.

WARNING!

Clear CMOS Jumper: JBA T1

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. If you want to
clear the system configuration, use the JBAT1 (Clear CMOS Jumper ) to clear

Detect) EEPROM on the DRAM module. Setting to Yes enables DRAM
Frequency(MHz), DRAM CAS Latency, Bank Interleave, Row Precharge,
RAS Pulse, RAS to CAS and Burst Length automatically to be determined
by BIOS based on the configurations on the SPD. Selecting No allows
users to configure these fields manually.

DRAM Frequency(MHz)

The chipset supports synchronous and asynchronous mode
between host clock and DRAM clock frequency. Settings are:

HCLK The DRAM clock will be equal to the Host Clock.
HCLK-33 The DRAM clock will be equal to the Host Clock

minus 33MHz. For example, if the Host Clock is
133MHz, the DRAM clock will be 100MH.

HCLK+33 The DRAM clock will be equal to the Host Clock

plus 33MHz. For example, if the Host Clock is
100MHz, the DRAM clock will be 133MHz.

Auto BIOS will automatically determine the clock

frequency.

DRAM CAS Latency

This controls the timing delay (in clock cycles) before SDRAM
starts a read command after receiving it. Settings: 2, 2.5, 3, Auto.
2 (clocks) increases the system performance the most while 3
(clocks) provides the most stable performance.

Bank Interleave

This field enables or disables bank interleave for the installed
SDRAM. Disable the function if 16MB SDRAM is installed.
Settings: Disabled, Auto.

Row Precharge

This item controls the number of cycles for Row Address Strobe
(RAS) to be allowed to precharge. If insufficient time is allowed for
the RAS to accumulate its charge before DRAM refresh, refresh
may be incomplete and DRAM may fail to retain data. This item
applies only when synchronous DRAM is installed in the system.
Available settings: 3T, 2T, Auto.

RAS Pulse

This setting allows you to select the number of clock cycles

allotted for the RAS pulse width, according to DRAM
specifications. The less the clock cycles, the faster the DRAM
performance. Settings: 6T, 5T, Auto.

RAS to CAS

This field allows you to set the number of cycles for a timing delay
between the CAS and RAS strobe signals, used when DRAM is
written to, read from or refreshed. Faster speed offers faster
performance while slower speed offers more stable performance.
Settings: 3T, 2T, Auto.

Burst Length

This setting allows you to set the size of Burst-Length for DRAM.
Bursting feature is a technique that DRAM itself predicts the
address of the next memory location to be accessed after the first
address is accessed. To use the feature, you need to define the
burst length, which is the actual length of burst plus the starting
address and allows internal address counter to properly generate
the next memory location. The bigger the size, the faster the
DRAM performance. Settings: 4, 8, Auto.

DRAM Command Rate

This setting controls the SDRAM command rate. Selecting 1T allows
SDRAM signal controller to run at 1T (T=clock cycles) rate. Selecting 2T
makes SDRAM signal controller run at 2T rate. 1T is faster than 2T.
Setting options: 1T, 2T.

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.

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® 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

bus architecture.

Reserved The IRQ will be reserved for further request.

PCI/VGA Palette Snoop

PCI VGA palette is the set of colors currently used by the video device.
Some special VGA cards may not show colors correctly and need to look
into the video device’ s VGA palette to determine what colors are in use.
Then you have to turn on the palette “snoop”, permitting the palette
registers of both VGA devices to be identical. The setting must be set to
Enabled if any non-standard VGA adapter card, such as MPEG card,
installed in the system requires VGA palette snooping.

Assign IRQ For VGA/USB

Set to Enabled allows BIOS to assign an IRQ to VGA card/USB device.
Choose Disabled if you want to release the IRQ.

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.

T o 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 field of the ADV ANCED BIOS FEATURES
menu. If the SECURITY OPTION field 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.
