CAUTION!

1. While CPU overheat is detected, the system will automatically shutdown.

Please check if the CPU fan on the motherboard functions properly before

you resume the system. To improve heat dissipation, remember to spray

thermal grease between the CPU and the heatsink when you install the PC

system.

2. Do NOT use a 3.3V AGP card on the AGP slot of this motherboard!

It may cause permanent damage!

3. Power Management for USB 2.0 works fine under Microsoft®Windows®

XP SP1/2000 SP4. It may not work properly under Microsoft®Windows®

98/ME. Please refer to Microsoft®official document at

http://www.microsoft.com/whdc/hwdev/bus/USB/USB2support.mspx

4. Although this motherboard offers stepless control, it is not recommended

to perform over clocking. Frequencies other than the recommended CPU

bus frequencies may cause the instability of the system or damage the

CPU. The CPU host frequency of this motherboard is determined by the

jumper-setting. You must set the FSB jumper according to your AMD CPU

before you use the “Manual” option as the FSB setting in BIOS setup to

perform over clocking. Please check page 21 for details.

Chapter 2 Installation

748-M is a Micro ATX form factor (9.6-in x 8.0-in, 24.4 cm x 20.3 cm) motherboard.

Before you install the motherboard, please study the configuration of your chassis to

ensure that the motherboard fits into it.

Make sure to unplug the power cord before installing or

removing the motherboard. Failure to do so may cause physical

injuries to you and damages to motherboard components.

2.1 Screw Holes

Place screws into the holes indicated by circles to secure the motherboard to the

chassis.

Do not over-tighten the screws! Doing so may damage the

motherboard.

2.2 Pre-installation Precautions

Take note of the following precautions before you install motherboard components

or change any motherboard settings.

1. Unplug the power cord from the wall socket before touching any

component.

2. To avoid damaging the motherboard components due to static

electricity, NEVER place your motherboard directly on the carpet or

the like. Also remember to use a grounded wrist strap or touch a

safety grounded object before you handle components.

3. Hold components by the edges and do not touch the ICs.

4. Whenever you uninstall any component, place it on a grounded

antistatic pad or in the bag that comes with the component.

Before you install or remove any component, ensure that the

power is switched off or the power cord is detached from the

power supply. Failure to do so may cause severe damage to the

motherboard, peripherals, and/or components.

2.3 CPU Installation

Step 1. Unlock the socket by lifting the lever up to a 90oangle.

Step 2. Position the CPU directly above the socket such that its marked corner

matches the base of the socket lever.

Step 3. Carefully insert the CPU into the socket until it fits in place.

The CPU fits only in one correct orientation. DO NOT force the

CPU into the socket to avoid bending of the pins.

Step 4. When the CPU is in place, press it firmly on the socket while you push

down the socket lever to secure the CPU. The lever clicks on the side tab

to indicate that it is locked.

2.4 Installation of CPU Fan and Heatsink

This motherboard adopts 462-pin CPU socket to support AMD Athlon XP /

DuronCPU. It requires larger heatsink and cooling fan to dissipate heat. You

also need to spray thermal grease between the CPU and the heatsink to

improve heat dissipation. Make sure that the CPU and the heatsink are se-

curely fastened and in good contact with each other. Then connect the CPU

fan to the CPU_FAN connector (CPU_FAN1, see page 7, No. 2). For proper

installation, please kindly refer to the instruction manuals of the CPU fan and

the heatsink.

STEP 1:

Lift Up The Socket Lever

STEP 2/STEP 3:

Match The CPU Marked Corner

To The Socket Marked Corner

STEP 4:
