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 motherboard 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 motherboard whether there are any damages to
components and connectors on the board.
2. If you suspect this motherboard has been damaged, do not
connect power to the system. Contact your motherboard
vendor about those damages.

Notice:
1. 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) pops 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. Just
click the “Continue Anyway” button and go ahead the
installation.
2. USB 2.0 Driver Limitations:
2-1 The USB 2.0 driver only supports Windows XP and
Windows 2000.
2-2 If you connect a USB 2.0 hub to the root hub, plugging USB
devices into this hub, the system might not successfully
execute certain USB devices’ connection because it could
not recognize these devices.

Introduction
This motherboard has a Socket 478 for the Intel Pentium 4 /
Prescott type of processors supporting front side bus (FSB) speeds
up to 533/400 MHz.
This motherboard has the VIA P4M266A Northbridge and
VT8235CD Southbridge chipsets that support AC’ 97 audio
codec, and provide Ultra DMA 133/100/66/33 function. It
supports built-in USB 2.0 providing higher bandwidth. It
implements Universal Serial Bus Specification Revision 2.0 and
is compliant with UHCI 1.1 and EHCI 1.0. This motherboard has
three 32-bit PCI slots, one 4xAGP slot, one CNR
(Communications and Networking Riser) slot, and an onboard
10BaseT/100BaseTX Network interface (optional). In addition,
this motherboard has a full set of I/O ports including two PS/2
ports for mouse and keyboard, one serial port, one VGA port, one
parallel port, one optional LAN port, six USB2.0 ports– four backpanel ports and onboard USB header USB2 providing two extra
ports by connecting the Extended USB Module to the motherboard.
This motherboard is a Micro-ATX size motherboard and has
power connectors for an ATX power supply.
Note: You must initiate the HT CPU function through
BIOS setup. It is strongly recommended you refer
to Page 35 for relative details.
Key Features
This motherboard has these key features:
Socket 478 Processor
♦ The PGA Socket 478
♦ Supports Intel Pentium 4 / Prescott series CPU
♦ Supports a front-side bus (FSB) of 533/400 MHz
Chipset
There are VIA P4M266A Northbridge and VT8235CD
Southbridge in this chipset in accordance with an innovative and
scalable architecture with proven reliability and performance. A
few of the chipset’s advanced features are:

provides the bandwidth up to 266 MB/s and performance
necessary for even the most demanding Internet and 3D
graphics
♦ Support for an 4xAGP interface providing vivid 3D
graphics and video performance
♦ An ATA 133 interface on the chipset, which helps boost
system performance by providing a high-speed connection
to ATA 133 Hard Disk Drives, delivering maximum
sustained data transfer rates of 133 MB/sec
Additional key features include support for six USB ports, an
AC’97 link for audio and modem, hardware monitoring, and
ACPI/OnNow power management.
Memory Support
♦ The motherboard accommodates two 184-pin, 2.5V DDR
DIMM sockets with a total capacity of 2 GB system
memory.
