Product Warranty
BCM warrants to you, the original purchaser, that each of its products will be free from defects in materials and
workmanship for two years from the date of purchase.
This warranty does not apply to any products which have been repaired or altered by persons other than repair
personnel authorized by BCM, or which have been to misuse, abuse, accident or improper installation. BCM
assumes no liability under the terms of this warranty as a consequence of such events.
Because of BCM high quality-control standards and rigorous testing, most of our customers never need to use
our repair service. If any of BCM products is defective, it will be repaired or replaced at no charge during the
warranty period. For out-of-warranty repairs, you will be billed according to the cost of replacement materials,
service time, and freight. Please consult your dealer for more details. If you think you have a defective product,
follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU type and speed, BCM
products model name, hardware & BIOS revision number, other hardware and software used, etc.) Note
anything abnormal and list any on-screen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your manual, product, and any helpful
information available.
3. If your product is diagnosed as defective, obtain an RMA (return material authorization) number from
your dealer. This allows us to process your good return more quickly.
4. Carefully pack the defective product, a complete Repair and Replacement Order Card and a photocopy
proof of purchase date (such as your sales receipt) in a shippable container. A product returned without
proof of the purchase date is not eligible for warranty service.
Write the RMA number visibly on the outside of the package and ship it prepaid to your dealer.
Manual Objectives
This manual describes in detail the BCM MX45GM2 Mini-ITX motherboard.
We strongly recommend that you study this manual carefully before attempting to interface with MX45GM2 or
change the standard configurations. Whilst all the necessary information is available in this manual we would
recommend that unless you are confident, you contact your supplier for guidance.
Please be aware that it is possible to create configurations within the CMOS RAM that make booting impossible.
If this should happen, clear the CMOS settings, (see the description of the Jumper Settings for details).
If you have any suggestions or find any errors concerning this manual and want to inform us of these, please
contact our Customer Service department with the relevant details.

Safety Precautions
Always completely disconnect the power cord from your chassis whenever you work
with the hardware. Do not make connections while the power is on. Sensitive electronic
components can be damaged by sudden power surges. Only experienced electronics
personnel should open the PC chassis.
Always ground yourself to remove any static charge before touching the motherboard.
Modern electronic devices are very sensitive to static electric charges. As a safety
precaution, use a grounding wrist strap at all times. Place all electronic components in a
static-dissipative surface or static-shielded bag when they are not in the chassis.

Before you Proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
zUnplug the power cord from the wall socket before touching any
component.
zUse a grounded wrist strap or touch a safely grounded object or a
metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity
zHold components by the edges to avoid touching the ICs on
them.
zWhenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
zBefore you install or remove any component, ensure that the
power supply is 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.

1. Motherboard Overview
Before you install the motherboard, study the configuration of your chassis to ensure that the
motherboard fits into it. Refer to the chassis documentation before installing the motherboard.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and
damage motherboard components.
1.1.1 Placement Direction
When installing the motherboard, make sure that you place it into the chassis in the correct
orientation. The edge with external ports goes to the rear part of the chassis as indicated in
the image below.
1.1.2 Screw Holes
Place four (4) screws into the holes indicated by circles to secure the motherboard to the
chassis.
Do not over tighten the screws! Doing so can damage the
motherboard.
Place this side towards the rear of
the chassis

1.2 Central Processing Unit (CPU)
The motherboard comes with a surface mount designed for the Intel® socket P Penryn / Core
2 Duo CPU / Celeron processors.
Please note the marked corner (with gold
triangle) on the CPU. This mark should
match a specific corner on the socket to
ensure correct installation.
zMake sure the power is off before you install the CPU.
zAfter installing the CPU, connect the CPU fan cable to the
CPU_FAN1 connector to ensure system stability.
zYour boxed Intel® socket P Core 2 Duo CPU with 45nm process
package should come with installation instructions for the CPU or
heatsink.
zThe product warranty does not cover damage to the socket
contacts resulting from incorrect CPU installation/removal.

MX45GM2 User’s Manual
19
1.2.1 Installing the CPU
1. Locate the CPU socket on the
motherboard.
Before installing the CPU,
make sure that the socket
box is facing towards you.
2. The processor socket comes with a
screw to secure the processor, please
unlock the screw first.
3. Position the CPU above the socket
and the gold triangular mark on the
CPU must align with pin 1 of the CPU
socket.
4. Carefully insert the CPU into the
socket until it fits in place ‘Gold mark’.
5. Turn the screw to the lock position.
The CPU fits in only one
correct orientation. DO
NOT force the CPU into
the socket to prevent
bending the connectors
on the socket and
damaging the CPU.

20
After installation, make sure to plug-in the
ATX power cable to the motherboard.
1.2.2 Installing the CPU Heatsink and Fan
1. Screw down two fasteners at a time in a
diagonal sequence to secure the heatsink
and fan assembly in place.
2. Connect the CPU fan cable to the connector on the motherboard labelled
CPU_FAN1.
zDo not forget to connect the fan cables to the fan connectors.
Insufficient air flow inside the system may damage the
motherboard components, and hardware monitoring errors can
occur if you fail to plug this connector.
zThese are not jumpers! DO NOT place jumper caps on the fan
connectors.
