4.1 Anti-static Precautions 

WARNING: 

Failure to take ESD precautions during the installation of the IMB-G41A 

may result in permanent damage to the IMB-G41A and severe injury to 

the user. 

Electrostatic discharge (ESD) can cause serious damage to electronic components, 

including the IMB-G41A. Dry climates are especially susceptible to ESD. It is therefore 

critical that whenever the IMB-G41A or any other electrical component is handled, the 

following anti-static precautions are strictly adhered to. 

• Wear an anti-static wristband: - Wearing a simple anti-static wristband can 

help to prevent ESD from damaging the board. 

• Self-grounding:- Before handling the board touch any grounded conducting 

material. During the time the board is handled, frequently touch any 

conducting materials that are connected to the ground. 

• Use an anti-static pad: When configuring the IMB-G41A, place it on an 

antic-static pad. This reduces the possibility of ESD damaging the IMB-G41A. 

• Only handle the edges of the PCB:-: When handling the PCB, hold the PCB 

by the edges. 

4.2 Installation Considerations 

NOTE: 

The following installation notices and installation considerations should 

be read and understood before installation. All installation notices must 

be strictly adhered to. Failing to adhere to these precautions may lead 

to severe damage and injury to the person performing the installation. 

Page 48


Page 49 

WARNING: 

The installation instructions described in this manual should be 

carefully followed in order to prevent damage to the components and 

injury to the user. 

Before and during the installation please DO the following: 

• Read the user manual: 

o The user manual provides a complete description of the IMB-G41A 

installation instructions and configuration options. 

• Wear an electrostatic discharge cuff (ESD): 

o Electronic components are easily damaged by ESD. Wearing an ESD cuff 

removes ESD from the body and helps prevent ESD damage. 

• Place the IMB-G41A on an antistatic pad: 

o When installing or configuring the motherboard, place it on an antistatic 

pad. This helps to prevent potential ESD damage. 

• Turn all power to the IMB-G41A off: 

o When working with the IMB-G41A, make sure that it is disconnected from 

all power supplies and that no electricity is being fed into the system. 

Before and during the installation of the IMB-G41A DO NOT: 

• Remove any of the stickers on the PCB board. These stickers are required for 

warranty validation. 

• Use the product before verifying all the cables and power connectors are 

properly connected. 

• Allow screws to come in contact with the PCB circuit, connector pins, or its 

components.


4.2.1 Socket LGA775 CPU Installation 

NOTE: 

To enable Hyper-Threading, the CPU and chipset must both support it. 

WARNING: 

CPUs are expensive and sensitive components. When installing the 

CPU please be careful not to damage it in anyway. Make sure the CPU 

is installed properly and ensure the correct cooling kit is properly 

installed. 

The LGA775 socket is shown in Figure 4-1. 

Figure 4-1: Intel LGA775 Socket 

To install the CPU, follow the steps below. 

WARNING: 

DO NOT touch the pins at the bottom of the CPU. When handling the 

CPU, only hold it on the sides. 

Page 50


Page 51 

Step 1: Remove the protective cover. The black protective cover can be removed by 

pulling up on the tab labeled "Remove". See Figure 4-2. 

Figure 4-2: Remove Protective Cover 

Step 2: Open the socket. Disengage the load lever by pressing the lever down and 

slightly outward to clear the retention tab. Fully open the lever, then open the 

load plate. See Figure 4-3. 

Figure 4-3: CPU Socket Load Plate 

Step 3: Inspect the CPU socket. Make sure there are no bent pins and make sure the 

socket contacts are free of foreign material. If any debris is found, remove it with 

compressed air.


Step 4: Orientate the CPU properly. The contact array should be facing the CPU 

socket. 

Step 5: Correctly position the CPU. Match the Pin 1 mark with the cut edge on the 

CPU socket. 

Step 6: Align the CPU pins. Locate pin 1 and the two orientation notches on the CPU. 

Carefully match the two orientation notches on the CPU with the socket 

alignment keys. 

Step 7: Insert the CPU. Gently insert the CPU into the socket. If the CPU pins are 

properly aligned, the CPU should slide into the CPU socket smoothly. See 

Figure 4-4. 

Figure 4-4: Insert the Socket LGA775 CPU 

Step 8: Close the CPU socket. Close the load plate and engage the load lever by 

pushing it back to its original position. There will be some resistance, but will not 

require extreme pressure. 

Step 9: Connect the 12 V power to the board. Connect the 12 V power from the power 

supply to the board. Step 0:

4.2.2 Socket LGA775 Cooling Kit Installation 

WARNING: 

DO NOT use the original Intel® heat sink and fan. A proprietary one is 

recommended. 

Figure 4-5: Cooling Kits (CF-520 and CF-775A) 

The cooling kit can be bought from IEI. The cooling kit has a heatsink and fan. 

WARNING: 

Do not wipe off (accidentally or otherwise) the pre-sprayed layer of 

thermal paste on the bottom of the heat sink. The thermal paste 

between the CPU and the heat sink is important for optimum heat 

dissipation. 

To install the cooling kit, follow the instructions below. 

Step 1: Place the cooling kit onto the socket LGA775 CPU. Make sure the CPU 

cable can be properly routed when the cooling kit is installed. 

Step 2: Properly align the cooling kit. Make sure the four spring screw fasteners can 

pass through the pre-drilled holes on the PCB.


Step 3: Mount the cooling kit. Gently place the cooling kit on top of the CPU. Make 

sure the four threaded screws on the corners of the cooling kit properly pass 

through the predrilled holes on the bottom of the PCB. 

Step 4: Secure the cooling kit. From the solder side of the PCB, align the support 

bracket to the screw threads on heat sink that were inserted through the PCB 

holes. (See Figure 4-6)

NOTE: 

A jumper is a metal bridge used to close 

an electrical circuit. It consists of two or 

three metal pins and a small metal clip 

(often protected by a plastic cover) that 

slides over the pins to connect them. To 

CLOSE/SHORT a jumper means 

connecting the pins of the jumper with 

the plastic clip and to OPEN a jumper means removing the plastic clip 

from a jumper.

D Watchdog Timer 

Page 131


NOTE: 

The following discussion applies to DOS environment. Contact IEI support 

or visit the IEI website for specific drivers for other operating systems. 

The Watchdog Timer is provided to ensure that standalone systems can always recover 

from catastrophic conditions that cause the CPU to crash. This condition may have 

occurred by external EMIs or a software bug. When the CPU stops working correctly, 

Watchdog Timer either performs a hardware reset (cold boot) or a Non-Maskable Interrupt 

(NMI) to bring the system back to a known state. 

A BIOS function call (INT 15H) is used to control the Watchdog Timer. 

INT 15H: 

AH – 6FH Sub-function: 

AL – 2: 

BL: 

Sets the Watchdog Timer’s period. 

Time-out value (Its unit-second is dependent on the item “Watchdog 

Timer unit select” in CMOS setup). 

Table D-1: AH-6FH Sub-function 

Call sub-function 2 to set the time-out period of Watchdog Timer first. If the time-out value 

is not zero, the Watchdog Timer starts counting down. When the timer value reaches zero, 

the system resets. To ensure that this reset condition does not occur, calling sub-function 

2 must periodically refresh the Watchdog Timer. However, the watchdog timer is disabled 

if the time-out value is set to zero. 

A tolerance of at least 10% must be maintained to avoid unknown routines within the 

operating system (DOS), such as disk I/O that can be very time-consuming. 

Page 132

NOTE: 

When exiting a program it is necessary to disable the Watchdog Timer, 

otherwise the system resets.
