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 nearthe
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.
The following processor is currently supported by this mainboard.
Intel P4 478: 1.4GHz ~ 2.2GHz, FSB: 400MHz

socket (the corner with the
pinhole noticeably missing).
Insert the processor into the
socket. Do not use force.
4. Lower the heatsink over the CPU.
5. Lower the CPU cooling fan onto the heatsink.
6. Apply thermal grease to the top of the CPU.

13
7. Swing the locking lever down
and hook it under the latch on
the edge of the socket.
8. Snap the four retention legs of
the cooling fan into place. Cooling Fan

Heatsink
9. Swing both lock levers on top of the cooling fan to their opposite sides to
secure the cooling fan on top of the heatsink.
10. Connect the CPU Cooling Fan
power cable to the CPUFAN1
connector.
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
The mainboard has two 168-pin/184-pin DIMM sockets for SDRAM/DDR
(Double Data Rate) SDRAM system memory modules.
The CPU supports 400MHz system bus. The SDRAM DIMMs and DDRs can
synchronously work with 100 MHz or operates over a 266 MHz system bus.
SDRAM provides 800 MB/s or 1 GB/s data transfer rate corresponding with
the bus 100 MHz or 133 MHz. It doubles the rate to 1.6 GB/s and 2.1 GB/s 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.
Installation Procedure
You must install at least one memory
module in order to use the main-
board.
Note: You cannot use DDR
SDRAM and SDRAM
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:
Cutout

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 33/66/100/133. UDMA is a technology
that accelerates the performance of devices in the IDE channel. To maximize
performance, install IDE devices that support UDMA and use 80-pin IDE ca-
bles that support UDMA 33/66/100/133.
Note: If your mainboard incorporates the SiS962 Southbridgechipset,theUltra
DMA bus mastering can support up to 133 MB/sec transfer rates. Other-
wise, the SiS961 Southbridge chipset can only support up to 100 MB/sec.
Installing a Hard Disk Drive
1. Install the hard disk drive into the drive cage in your system case.
2. Plug the IDE cable into IDE1
(A):
Note: Ribbon cable connectors
are usually keyed so that they can
only be installed correctly on the
device connector. If the connector
is not keyed, make sure that you
match the pin-1 side of the cable
connector with the pin-1 side of the
device connector. Each connector
has the pin-1 side clearly marked.
The pin-1 side of each ribbon ca-
ble is always marked with a
colored stripe on the cable.

3. Plug an IDE cable connector into the hard disk drive IDE connector (B). It
doesn't matter which connector on the cable you use.
4. Plug a power cable from the case power supply into the power connector on
the hard disk drive (C).
When you first start up your system, the BIOS should automatically detect
your hard disk drive. If it doesn’t, enter the Setup Utility and use the IDE Hard
Disk Auto Detect feature to configure the hard disk drive that you have in-
stalled.
Installing a CD-ROM/DVD Drive
1. Install the CD-ROM/DVD drive into the drive cage in your system case.
2. Plug the IDE cable into IDE1
(A). If you have already installed
an HDD, use the other connec-
tor on the IDE cable.
Note: Ribbon cable connectors are
usually keyed so that they can only
be installed correctly on the device
connector. If the connector is not
keyed, make sure that you match the
pin-1 side of the cable connector with
the pin-1 side of the device connec-
tor. Each connector has the pin-1
side clearly marked. The pin-1 side of
each ribbon cable is always marked
with a colored stripe on the cable.
3. Plug an IDE cable connector into the CD-ROM/DVD drive IDE connector (B). It
doesn't matter which connector on the cable you use.
4. Plug a power cable from the case power supply into the power connector on
the CD-ROM/DVD drive (C).
5. Use the audio cable provided with the CD-ROM/DVD drive to connect to the
mainboard CD-in connector CDIN1 or CDIN2 (D).
When you first start up your system, the BIOS should automatically detect
your CD-ROM/DVD drive. If it doesn’t, enter the Setup Utility and configure
the CD-ROM/DVD drivethat you have installed.
