Chapter 1 Introduction
Thank you for choosing this mainboard. It is a high performance
and high quality mainboard which is built around the latest and
fastest VIA KT266A + VT8235 chipset providing superior
performance between the CPU, DRAM, AGP bus, and V-Link bus
with pipelined, burst and concurrent operation. This mainboard
supports Socket 462 that accommodates AMD Athlon processors
with a frontside bus (FSB) speeds up to 133MHz.
The KT266A supports two banks of DDR Synchronous DRAMs
up to 2GB for unbuffered modules. It also fully supports full AGP
v2.0 capability for maximum bus utilization including 1x, 2x and
4x mode transfers, SBA (SideBand Addressing), Flush/Fence
commands and pipelined grants.
The VT8235 Southbridge supports standard intelligent peripheral
controllers such as USB v2.0/1.1 and Universal HCI v2.0/1.1
compliant, real time clock with 256 byte extended CMOS,
integrated bus-mastering dual full-duplex direct-sound AC97 link
compatible sound system and full System Management Bus
(SMBus) interface.
Sufficient expansion is provided for with one AGP slot, five 32-bit
PCI slot and an optional CNR slot. It also comes with a built-in
Enhanced PCI Bus Master PCI IDE controller that provides high-
speed connections to full range of IDE devices such as HDD and
CD-ROM. This mainboard is designed in a standard ATX form
factor using a 4-layer printed circuit board and measures 305 mm x

Installing the Processor
This mainboard has a Socket 462 processor socket. When choosing
a processor, 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.
CPU Installation Procedure
Follow these instructions to install the CPU:
1. Unhook the CPU socket’s locking lever by pulling
it away from socket and raising it to the upright
position.
2. Match the pin1 corner on the CPU (the beveled
edge) with the pin1 corner on the socket (at the
base of the locking lever). Insert the CPU into the
socket. Do not use force.
3. Push the locking lever down and hook it under the
latch on the edge of socket.
4. Apply thermal grease to the top of the CPU.
5. Lower the CPU fan/heatsink unit onto the CPU.
6. Secure two retention clips on either side of the
fan/heatsink unit onto the socket base.
7. Connect the CPU fan power cable to the CPU fan
connector on the mainboard.
Installing Memory Modules
This mainboard accommodates two 184-pin 2.5V unbuffered
Double Data Rate (DDR) SDRAM memory modules. Each module
can be installed with 32 MB to 1 GB of memory; total memory
capacity is 2GB.
Note: Double Data Rate SDRAM (DDR SDRAM) doubles the rate to
1.6 GBps and 2.1 GBps. DDR SDRAM uses additional power
and ground lines and requires 184-pin DIMM modules rather
than the 168-pin DIMMs used by SDRAM.
10

Do not remove any memory module from its antistatic
packaging until you are ready to install it on the mainboard.
Handle the modules only by their edges. Do not touch the
components or metal parts. Always wear a grounding strap
when you handle the modules.
DDR2
DDR1
Installation Procedure
These modules can be installed with up to 2 GB system memory.
Refer to the following to install the memory module.
1. Push the latches on each side of the DIMM socket
down.
2. Align the memory module with the socket. The
DIMM sockets 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 socket.
4. Install the DIMM module into the socket and press
it firmly down until it is seated correctly. The
socket latches are levered upwards and latch on to
the edges of the DIMM.
5. Install any remaining DIMM modules.
