1. JP14 Clear CMOS

You can clear CMOS to restore system default setting. To
clear the CMOS, follow the procedure below.

1. Turn off the system and unplug the AC power.

2. Remove ATX power cable from connector PWR2.

3. Locate JP14 and short pins 2-3 for a few seconds.

4. Return JP14 to its normal setting by shorting pin 1 & pin 2.

5. Connect ATX power cable back to connector PWR2.

CPU Pin 1 and cut edge

1. Pull up the CPU socket level and up to
90-degree angle.

2. Locate Pin 1 in the socket and look for a
(golden) cut edge on the CPU uppe
interface. Match Pin 1 and cut edge.
Then insert the CPU into the socket.

3. Press down the CPU socket level and
finish CPU installation.

Note: If you do not match the CPU
socket Pin 1 and CPU cut edge
well, it may damage the CPU.

5. Setting CPU Voltage & Frequency

Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically

detected and the range is from 1.05V to 1.825V. It is not necessary to set CPU Core Voltage

Setting CPU Frequency

This motherboard is CPU jumper-less design, you can set CPU frequency through the BIOS
setup, no jumpers or switches are needed.

BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
Core Frequency = CPU FSB Clock * CPU Ratio

14. Support 10/100 Mbps LAN onboard

16. Wake On LAN

The South Bridge V8233 of VIA Apollo Pro266T chipset includes a fast Ethernet controller on
chip. On the strength of Intel 82550 PHY on board, which is a highly-integrated Platform LAN
Connect device, it provides 10/100M bps Ethernet for office and home use, the Ethernet RJ45
connector is located on the back panel. The green LED indicates the link mode, it lights when
linking to network and blinking when transferring data. The orange LED indicates the transfer
mode, and it lights when data is transferring in 100Mbps mode. To enable or disable this
function, you may simply adjust it through BIOS.

Green/ACT

Orange/Speed

15. Power-On and Load BIOS Setup

To use Wake On LAN function, you must have a network card with chipset that supports this
feature, and connect a cable from LAN card to motherboard WOL connector. The system
identification information (probably IP address) is stored on network card and because there is
a lot of traffic on the Ethernet, you need to install a network management software, such as
ADM, for the checking of how to wake up the system. Note that, at least 600mA ATX standby
current is required to support the LAN card for this function.
