Mainboard Hardware
1.2CPU
This mainboard supports Intel® P4 Northwood up to 3.2GHz and Prescott up to
3.4GHz. The mainboard uses a CPU socket called PGA478 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. Remember to peel off the sticker before
you install the CPU cooler. For information on how to install the CPU and cooler, refer
to Quick Installation Guide.
The mainboard provides 2 slots for 184-pin DDR SDRAM
DIMM (Double In-Line Memory Module) modules and supports the
memory size up to 2GB. You can install DDR400/DDR333/DDR266
modules into the DDR DIMM slots.
1.3 Memory
DIMM1 DIMM2
Note:
1. Read the instructions on the cooler before you start the installation.
2. Overheating will seriously damage the CPU and system, always make
sure the cooling fan can work properly to protect the CPU from overheating.
DIMM Module Combination
Install at least one DIMM module on the slots. You can install either single- or
double-sided modules in any order to meet your own needs. Memory modules can be
installed in any combination as follows:
S: Single Side
D: Double Side
Slot MemoryModule Total Memory
DIMM1 DDR S/D 64MB~1GB
(Bank 0 & 1)
DIMM2 DDR S/D 64MB~1GB

1.5 Front panel
The Front Panel is independent and extended from the mainboard. It’s con-
nected to the Front I/O Connector on the mainboard. You can find the following ports
on the Front Panel.
IEEE 1394 Port: J1394-2
The mainboard provides two IEEE 1394 ports. This smaller one is designed
for you to connect the IEEE 1394 device with external power. The IEEE 1394 high-
speed serial bus complements USB by providing enhanced PC connectivity for a
wide range of devices, including consumer electronics audio/video (A/V) appliances,
storage peripherals, other PCs, and portable devices.
Software Support
IEEE 1394 Driver is provided by Windows®98 SE, Windows®XP, Win-
dows®ME and Windows®2000. Just plug in the IEEE 1394 connector into
the port. These Operating Systems will install the driver for IEEE 1394.
IEEE 1394 Port: J1394-1
The bigger 6-pin IEEE 1394 Port on the front panel is designed for you to
connect to IEEE 1394 devices without external power. That means the mainboard can
provide the power for the devices connected to this port.

1.8Jumper
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 2 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:

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.

1.9 Slots
AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert theAGP 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 4x/8x throughputs.
PCI Slot
The PCI slot allows you to insert PCI card or TV Tuner card. 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.
