Chapter 2 Installation

775i48-M is a Micro ATX form factor (9.6" x 8.0", 24.4 x 20.3 cm) motherboard. Before you install the motherboard, 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.
2.3 775-LAND CPU Installation
For the installation of Intel 775-LAND CPU, please follow the steps below.

775-Pin Socket Overview

Before you insert the 775-LAND CPU into the socket, please check if the CPU surface is unclean or if there is any bent pin on the socket. Do not force to insert the CPU into the socket if above situation is found. Otherwise, the CPU will be seriously damaged.
Step 1. Open the socket: Step 1-1. Disengaging the lever by depressing down and out on the hook to clear retention tab.
Step 1-2. Rotate the load lever to fully open position at approximately 135 degrees. Step 1-3. Rotate the load plate to fully open position at approximately 100 degrees. Step 2. Insert the 775-LAND CPU: Step 2-1. Hold the CPU by the edges where are marked with black lines.

black line

Step 2-2. Orient the CPU with IHS (Integrated Heat Sink) up. Locate Pin1 and the two orientation key notches.

Pin1 orientation key notch orientation key notch Pin1 alignment key alignment key
775-Pin Socket 775-LAND CPU
For proper inserting, please ensure to match the two orientation key notches of the CPU with the two alignment keys of the socket.
Step 2-3. Carefully place the CPU into the socket by using a purely vertical motion. Step 2-4. Verify that the CPU is within the socket and properly mated to the orient keys. Step 3. Remove PnP Cap (Pick and Place Cap): Use your left hand index finger and thumb to support the load plate edge, engage PnP cap with right hand thumb and peel the cap from the socket while pressing on center of PnP cap to assist in removal.
It is recommended to use the cap tab to handle and avoid kicking off the PnP cap.
Step 4. Close the socket: Step 4-1. Rotate the load plate onto the IHS. Step 4-2. While pressing down lightly on load plate, engage the load lever. Step 4-3. Secure load lever with load plate tab under retention tab of load lever.
Installation of CPU Fan and Heatsink
This motherboard is equipped with 775-Pin socket that supports Intel 775-LAND CPU. Please adopt the type of heatsink and cooling fan compliant with Intel 775-LAND CPU to dissipate heat. Before you installed the heatsink, you need to spray thermal interface material between the CPU and the heatsink to improve heat dissipation. Ensure that the CPU and the heatsink are securely fastened and in good contact with each other. Then connect the CPU fan to the CPU_FAN connector (CPU_FAN1, see page 8, No. 29).
For proper installation, please kindly refer to the instruction manuals of your CPU fan and heatsink.
Below is an example to illustrate the installation of the heatsink for 775-LAND CPU. Step 1. Apply thermal interface material onto center of IHS on the socket surface.

Step 2.

Step 3. Step 4.
Place the heatsink onto the socket. Ensure fan cables are oriented on side closest to the CPU fan connector on the motherboard (CPU_FAN1, see page 8, No. 29). Align fasteners with the motherboard throughholes. Rotate the fastener clockwise, then press down on fastener caps with thumb to install and lock. Repeat with remaining fasteners.
If you press down the fasteners without rotating them clockwise, the heatsink cannot be secured on the motherboard.

Step 5. Step 6.

Connect fan header with the CPU fan connector on the motherboard. Secure excess cable with tie-wrap to ensure cable does not interfere with fan operation or contact other components.
2.5 Installation of Memory Modules (DIMM)
775i48-M motherboard provides two 184-pin DDR (Double Data Rate) DIMM slots.
Please make sure to disconnect power supply before adding or removing DIMMs or the system components.

Step 1. Step 2.

Unlock a DIMM slot by pressing the retaining clips outward. Align a DIMM on the slot such that the notch on the DIMM matches the break on the slot.

Note: CLRCMOS0 allows you to clear the data in CMOS. The data in CMOS includes system setup information such as system password, date, time, and system setup parameters. To clear and reset the system parameters to default setup, please turn off the computer and unplug the power cord, then use a jumper cap to short the pins on CLRCMOS0 for 3 seconds. Please remember to remove the jumper cap after clearing the CMOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action.
2.8 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over these headers and connectors. Placing jumper caps over the headers and connectors will cause permanent damage of the motherboard!

(4-pin ATX12V1) (see p.8, No. 2)
Please note that it is necessary to connect a power supply with ATX 12V plug to this connector so that it can provides sufficient power. Failing to do so will cause the failure to power up.
Serial ATA (SATA) Hard Disks Installation
This motherboard adopts Intel ICH5 south bridge chipset that supports Serial ATA (SATA) hard disks. You may install SATA hard disks on this motherboard for internal storage devices. This section will guide you to install the SATA hard disks. STEP 1: Install the SATA hard disks into the drive bays of your chassis. STEP 2: Connect the SATA power cable to the SATA hard disk. STEP 3: Connect one end of the SATA data cable to the motherboards primary SATA connector (SATA1). STEP 4: Connect the other end of the SATA data cable to the primary SATA hard disk. If you just want to install only one SATA HDD, the installation process is complete at this step. If you want to install two SATA HDDs, please continue to do the following steps. STEP 5: Connect the SATA power cable to the SATA hard disk. STEP 6: Connect one end of the second SATA data cable to the motherboards secondary SATA connector (SATA2). STEP 7: Connect the other end of the SATA data cable to the secondary SATA hard disk.
Before you install OS into the SATA hard disk, you need to check and ensure the configuration of the OnBoard IDE Operate Mode option in BIOS setup is correct according to the condition of your system. For the configuration details, please refer to the instruction on page 27.
