2-3 Glossary
Chipset (core logic) -two or more integrated circuits which control the interfaces between the
system processor, RAM, I/O devises, and adapter cards.
Processor socket - the socket used to mount the system processor on the motherboard.
Slot (AGP, PCI, ISA, RAM) - the slots used to mount adapter cards and system RAM.
AGP - Accelerated Graphics Port - a high speed interface for video cards; runs at 1X (66MHz), 2X
(133MHz), or 4X (266MHz).
PCI - Peripheral Component Interconnect - a high speed interface for video cards, sound cards,
network interface cards, and modems; runs at 33MHz.

CPU L2 Cache - The flash memory inside the CPU, normally Pentium III CPU has 256K or
above, while Celeron CPU will have 128K.
2-3-1 Setting CPU Bus Clock & Memory Clock Jumper
Setting the front side bus frequency and SDRAM frequency
The motherboard uses jumper less function for the front side bus frequency and SDRAM
frequency users don’t need setting any jumper when plug the CPU in motherboard
For experience user looking for over clocking possibility, please refer to sec 2-3-2.
2-3-2 Over clock Running
WARNING! This section is for experienced motherboard installer only. Over clocking
can result in system instability or even shortening life of the processor.
Users can choose over clock running by BIOS CMOS SETUP UTILITY. When you entered
CMOS SETUP UTILITY, choose “Miscellaneous Control” you will see the screen as below
then. Phoenix – AwardBIOS CMOS Setup Utility

WARNING! The Design of this motherboard follows chipset and CPU vender’s design
guideline. Any attempts to push beyond product specification are not
recommended and you are taking your own risk to damage your system or
important data. Before over clocking, you must make sure your
components are able to tolerate such abnormal setting, especially CPU,
memory, hard disks, and VGA cards.

2-4 Install Memory
The motherboards provide one 240-pin DUAL INLINE MEMORY MODULES (DIMM)
sites for memory expansion available from minimum memory size of 64MB to maximum
memory size of 1.0GB DDR2 SDRAM.
Valid Memory Configurations
Bank 240-Pin DIMM PCS Total Memory
Bank 0, 1 (DDR1) DDR2 533/DDR2 400
DDR2 SDRAM Module X1 64MB∼1.0GB
Total System Memory (Max. 1.0GB) 1 64MB∼1.0GB
Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer
to figure 2-4 to see what a 240-Pin DDR2 400/DDR2 533 DDR2 SDRAM module looks
like.
DIMM1 (BANK0+BANK1)
NOTE! When you install DIMM module fully into the DIMM socket the eject tab should be
locked into the DIMM module very firmly and fit into its indention on both sides.
WARNING! For the DDR SDRAM CLOCK is set at 133MHz, use only DDR266-compliant DDR
Modules. When this motherboard operate at 133MHz, most system will not even
boot if non-compliant modules are used because of the strict timing issues, if your
SDR Modules are not DDR266-compliant, set the DDR SDRAM clock to 100MHz
to ensure system stability.

2-5 Expansion Cards
WARNING! Turn off your power when adding or removing expansion cards or other system
components. Failure to do so may cause severe damage to both your
motherboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read the documentation for your expansion card and make any necessary hardware or software
setting for your expansion card such as jumpers.
2. Remove your computer’s cover and the bracket plate on the slot you intend to use.
3. Align the card’s connectors and press firmly.
4. Secure the card on the slot with the screen you remove above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively assign
to one use. In a standard design, there are 16 IRQs available but most of them are already in
use.
Standard Interrupt Assignments
IRQ Priority Standard function
0 N/A System Timer
1 N/A Keyboard Controller
2 N/A Programmable Interrupt
3 * 8 Communications Port (COM2)
4 * 9 Communications Port (COM1)
5 * 6 Sound Card (sometimes LPT2)
6 * N/A Floppy Disk Controller
7 * 7 Printer Port (LPT1)
8 N/A System CMOS/Real Time Clock
9 * 10 ACPI Mode when enabled
10 * 3 IRQ Holder for PCI Steering
11 * 2 IRQ Holder for PCI Steering
12 * 4 PS/2 Compatible Mouse Port
13 N/A Numeric Data Processor
14 * 5 Primary IDE Channel
15 * N/A Secondary IDE Channel
* These IRQs are usually available for ISA or PCI devices.
2-5-3 Interrupt Request Table For This Motherboard
Interrupt request are shared as shown the table below:
INT A INT B INT C INT D INT E INT F INT G INT H
Slot 1 √
Onboard VGA √
Onboard USB 1 √
Onboard USB 2 √
LAN
√
AC97/MC97

IMPORTANT! If using PCI cards on shared slots, make sure that the drivers support “Shared IRQ” or
that the cards don’t need IRQ assignments. Conflicts will arise between the two PCI
groups that will make the system unstable or cards inoperable.

2-6 Connectors, Headers
2-6-1 Connectors
(1) Power Connector (24-pin block) : ATXPWR
ATX Power Supply connector. This is a new defined 24-pins connector that usually comes with
ATX case. The ATX Power Supply allows to use soft power on momentary switch that connect from
the front panel switch to 2-pins Power On jumper pole on the motherboard. When the power
switch on the back of the ATX power supply turned on, the full power will not come into the system
board until the front panel switch is momentarily pressed. Press this switch again will turn off the
power to the system board.
** We recommend that you use an ATX 12V Specification 2.0-compliant power supply unit (PSU)
with a minimum of 80W power rating. This type has 24-pin and 4-pin power plugs.
** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin power plug
can provide at least 6.6A on +12V and the power supply unit has a minimum power rating of 80W.
The system may become unstable or may not boot up if the power is inadequate.
(2)PS/2 Mouse & PS/2 Keyboard Connector: KB/MS1
If you are using a PS/2 mouse, you must purchase an optional PS/2 mouse set which
connects to the 5-pins block and mounts to an open slot on your computer’s case.

2-7 Starting Up Your Computer
1. After all connections are made, close your computer case cover.
2. Be sure all the switch are off, and check that the power supply input voltage is set to
proper position, usually in-put voltage is 220V∼240V or 110V∼120V depending on your
country’s voltage used.
3. Connect the power supply cord into the power supply located on the back of your system
case according to your system user’s manual.
4. Turn on your peripheral as following order:
a. Your monitor.
b. Other external peripheral (Printer, Scanner, External Modem etc…)
c. Your system power. For ATX power supplies, you need to turn on the power supply
and press the ATX power switch on the front side of the case.
5. The power LED on the front panel of the system case will light. The LED on the
monitor may light up or switch between orange and green after the system is on. If it
complies with green standards or if it is has a power standby feature. The system will
then run power-on test. While the test are running, the BIOS will alarm beeps or
additional message will appear on the screen.
If you do not see any thing within 30 seconds from the time you turn on the power. The
system may have failed on power-on test. Recheck your jumper settings and connections
or call your retailer for assistance.
Beep Meaning
One short beep when displaying logo No error during POST
Long beeps in an endless loop No DRAM install or detected
One long beep followed by three short
beeps Video card not found or video card memory bad
High frequency beeps when system is
working CPU overheated
System running at a lower frequency
6. During power-on, press <Delete> key to enter BIOS setup. Follow the instructions in
BIOS SETUP.
7. Power off your computer: You must first exit or shut down your operating system
before switch off the power switch. For ATX power supply, you can press ATX power
switching after exiting or shutting down your operating system. If you use Windows 9X,
click “Start” button, click “Shut down” and then click “Shut down the computer?”
The power supply should turn off after windows shut down.
