1. JP3 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.

3. Locate JP3 and short pins 2-3 for a few seconds.

4. Return JP3 to its normal setting by shorting pin 1 & pin 2.

5. Connect ATX power cable back.

3. Installing Processor

CPU socket lever

CPU Pin 1 and cut edge

1. Pull up the CPU socket lever 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 lever 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.

4. Supported CPU Type

Fortress1100 supports one Coppermine (up to 1 GHz with 256 L2 cache) or Tualatin
(up to 1.26 GHz with 512K L2 cache) processor with external FSB up to 133 MHz.

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, the system can detect the CPU frequency
automatically, and no jumpers or switches are needed.

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

This jumper allows you to decide the system to support IDE RAID or ATA interface. The
default setting is IDE RAID.

The system is equipped with an intrusion alarm device. Whenever the opening of
the chassis triggers the sensor, the system will send out beep sound to inform
you. The connector is equipped with a foolproof device.

11. Connecting IDE and Floppy Cables

The system comes with a slim-type CD-ROM drive and a slim-type floppy disk drive.
Connect 40-pin, 80-wire IDE cable to IDE connector. A slim-type floppy disk drive is
connected with a special design cable. Be careful of the pin1 orientation. Wrong
orientation may cause system damage.

14. Support 10/100 Mbps LAN Onboard

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.
