Static Electricity Precautions
Static electricity could damage components on this motherboard.
Take the following precautions while unpacking this motherboard
and installing it in a system.
1. Don’t take this mainboard and components out of their
original static-proof package until you are ready to install
them.
2. While installing, please wear a grounded wrist strap if
possible. If you don’t have a wrist strap, discharge static
electricity by touching the bare metal of the system chassis.
3. Carefully hold this motherboard by its edges. Do not touch
those components unless it is absolutely necessary. Put this
motherboard on the top of static-protection package with
component side facing up while installing.
Pre-Installation Inspection
1. Inspect this mainboard whether there are any damages to
components and connectors on the board.
2. If you suspect this mainboard has been damaged, do not
connect power to the system. Contact your motherboard
vendor about those damages.

Notice:
Owing to Microsoft’s certifying schedule is various to every
supplier, we might have some drivers not certified yet by
Microsoft. Therefore, it might happen under Windows XP that
a dialogue box (shown as below) pop out warning you this
software has not passed Windows Logo testing to verify its
compatibility with Windows XP. Please rest assured that our
RD department has already tested and verified these drivers.

Chapter1:Introduction
Chapter 1 Introduction
This motherboard has a Socket-478 supporting Intel Pentium 4/
Prescott with Hyper-Threading Technology processors with
Front-Side Bus (FSB) speeds up to 533/400 MHz. Hyper-
Threading Technology, designed to take advantage of the
multitasking features in Windows XP, gives you the power to do
more things at once.
Note: It supports Hyper-Threading Technology only when the
Intel 845GV is installed. Intel 845GL supports FSB 533 MHz
only by overclocking.
This motherboard has the Intel 845GL/GV chipset that contains
Intel 82845 Memory Controller Hub and Intel 82801 I/O Control-
ler Hub. It supports built-in USB 2.0 providing higher bandwidth.
It implements Universal Serial Bus Specification Revision 2.0
and includes three UHCI host controllers that support six external
ports. This motherboard supports AC’ 97 audio codec and
provides Ultra DMA 100/66/33 function.
This motherboard has one CNR (Communications and Network-
ing Riser), three 32-bit PCI slots and one AGPro slot. There is a
full set of I/O ports including two PS/2 ports for mouse and
keyboard and audio jacks for microphone, line-in and line-out.
There are one serial port, one VGA port, one parallel port, one
LAN port(optional), and six USB ports (USB2.0)–four back-
panel ports and onboard USB header USB3 providing two extra
ports by connecting the Extended USB Module to the
motherboard.
This motherboard is a Micro ATX motherboard that uses a 4-
layer printed circuit board and measures 244 x 220mm.
