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

Mainboard Hardware
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.
