Introducing the Mainboard
I
In nt tr ro od du uc ct ti io on n
Thank you for choosing this mainboard. This mainboard has a Socket-478
processor socket for Intel Pentium 4 type of processors supporting front side
bus (FSB) speeds up to 533 MHz.
This mainboard incorporates the VIA P4X333 Northbridge and
VT8235/8233A(CE) Southbridge chipsets that support AC 97 audio codec,
and provide Ultra DMA 33/66/100/133 function. If the VT8235 SB is installed,
the mainboard supports built-in USB 2.0 providing higher bandwidth, imple-
ments Universal Serial Bus Specification Revision 2.0 and is compliant with
UHCI 1.1 and EHCI 0.95; if the VT8233A(CE) SB, it doesn’t support USB2.0
and without LAN. This mainboard has four 32-bit PCI slots, one 4xAGP slot,
one CNR (Communications and Networking Riser) slot, and an onboard
10BaseT/100BaseTX Network interface (optional).
There is a full set of I/O ports including two PS/2 ports for mouse and key-
board, two serial ports, one parallel port, one MIDI/game port and maximum
six USB ports --two back-panel ports and onboard USB headers make four
extra USB ports by connecting the Extended USB Module to the mainboard.

There are many types of computer cases on the market. The mainboard com-
plies with the specifications for the ATX system case. Some features on the
mainboard are implemented by cabling connectors on the mainboard to indi-
cators and switches on the system case. Ensure that your case supports all
the features required. The mainboard can support one or two floppy diskette
drives and four enhanced IDE drives. Ensure that your case has sufficient
power and space for all the drives that you intend to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that
the I/O template in the case matches the I/O ports installed on the rear edge
of the mainboard.
This mainboard has an ATX form factor of 305 x 244 mm. Choose a case that
accommodates this form factor.

Follow these safety precautions when installing the mainboard:
• Wear a grounding strap attached to a grounded device to avoid
damage from static electricity.
• Discharge static electricity by touching the metal case of a safely
grounded object before working on the mainboard.
• Leave components in the static-proof bags they came in.
• Hold all circuit boards by the edges. Do not bend circuit boards.

Most system cases have
mounting brackets installed in
the case, which correspond to
the holes in the mainboard.
Place the mainboard over the
mounting brackets and secure
the mainboard onto the mount-
ing brackets with screws.
2. Secure the mainboard with

This section explains how to set jumpers for correct configuration of the main-
board.
Setting Jumpers
Use the mainboard jumpers to set system configuration options. Jumpers with
more than one pin are numbered. When setting the jumpers, ensure that the
jumper caps are placed on the correct pins.
The illustrations below show a 2-pin jumper.
When the jumper cap is placed on both pins,
the jumper is SHORT. If you remove the
jumper cap, or place the jumper cap on just
one pin, the jumper is OPEN.
This illustration shows a 3-pin
jumper. Pins 1 and 2 are SHORT.

Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the mainboard or any of the surface-mount resistors
with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the mainboard, you may cause serious damage to the mainboard
or its components.
On most mainboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the mainboard and processor socket.
Before installing the Processor
This mainboard automatically determines the CPU clock frequency and sys-
tem bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the mainboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
overclock processors or other components to run faster than their rated speed.
Warning: Overclocking components can adversely affect the reliability of
the system and introduce errors into your system. Overclocking can per-
manently damage the mainboard by generating excess heat in
components that are run beyond the rated limits.
This mainboard has a Socket 478 processor socket. When choosing a proc-
essor, consider the performance requirements of the system. Performance is
based on the processor design, the clock speed and system bus frequency of
the processor, and the quantity of internal cache memory and external cache
memory.
12

CPU Installation Procedure
The following illustration shows CPU installation components:
Note: The pin-1 corner is marked with an arrow
Follow these instructions to install the Retention Module and CPU:
1. Remove the existing retention module (if applicable).
2. Position the backplate
against the underside of
the mainboard, secure
the 4 screws firmly on
the retention module.
Note: Do not over tighten
the screws.
3. Install your CPU. Pull up
the lever away from the
socket and lift up to 90-
degree angle.
13

4. Locate the CPU cut
edge (the corner with the
pinhole noticeably miss-
ing). Align and insert the
CPU correctly.
5. Press the lever down.
6. Apply thermal grease on top of the CPU.
7. Put the CPU Fan down
on the retention module
and snap the four reten-
tion legs of the cooling
fan into place.
8. Flip the levers over to lock the heat sink in place.
9. Connect the CPU Cool-
ing Fan power cable to
the CPUFAN1 connec-
tor. This completes the
installation.
Note: CPU fan and heatsink installation procedures may vary with the type of
CPU fan/heatsink supplied. The form and size of fan/heatsink may also
vary.
14

Installing Memory Modules
This mainboard accommodates 168-pin 3.3V/184-pin 2.5V unbuffered
SDRAM memory modules.
The CPU supports 100MHz system bus. The SDRAM DIMMs and DDRs can
synchronously work with 100 MHz or operates over a 133 MHz system bus.
DDR SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100 MHz or 133 MHz. It doubles the rate to 1.6 GBps and
2.1 GBps by transferring data on both the rising and falling edges of the clock.
DDR SDRAM uses additional power and ground lines and requires 184-pin
2.5V unbuffered DIMM module rather than the 168-pin 3.3V unbuffered
DIMMs used by SDRAM.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the mainboard. Handle the modules only by
their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.
Note: You must install at least one memory module in order to have the main-
board work properly, either SDRAM or DDR SDRAM, but you can’t
use them simultaneously.
Refer to the following to install the memory modules.
1. Push the latches on each side of the DIMM slot down.
2. Align the memory module with the slot. The DIMM slots are keyed
with notches and the DIMMs are keyed with cutouts so that they can
only be installed correctly.
3. Check that the cutouts on the DIMM module edge connector match
the notches in the DIMM slot:

4. Install the DIMM module into the slot and press it firmly down until it
seats correctly. The slot latches are levered upwards and latch on to
the edges of the DIMM.
5. Install any remaining DIMM modules.
Installing a Hard Disk Drive/CD-ROM
This section describes how to install IDE devices such as a hard disk drive
and a CD-ROM drive.
About IDE Devices
Your mainboard has a primary and secondary IDE channel interface (IDE1 and
IDE2). An IDE ribbon cable supporting two IDE devices is bundled with the main-
board.
If you want to install more than two IDE devices, get a second IDE cable and
you can add two more devices to the secondary IDE channel.
IDE devices have jumpers or switches that are used to set the IDE device as
MASTER or SLAVE. Refer to the IDE device user’s manual. When installing two
IDE devices on one cable, ensure that one device is set to MASTER and the
other device is set to SLAVE. The documentation of your IDE device explains
how to do this.
About UltraDMA
This mainboard supports UltraDMA 66/100/133. UDMA is a technology that
accelerates the performance of devices in the IDE channel. To maximize per-
formance, install IDE devices that support UDMA and use 80-pin IDE cables
that support UDMA 66/100/133.
