Chapter 2: Installation
This is a Mini-ITX form factor (6.7" x 6.7", 17.0 x 17.0 cm) motherboard. Before you
install the motherboard, study the conguration of your chassis to ensure that the
motherboard ts 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 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 o󰀨 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.

12
2.3 Installation of Memory Modules (SO-DIMM)
IMB-151D-WF motherboard provides two 204-pin DDR3 (Double Data Rate 3) SO-
DIMM slots, which support Dual Channel DDR3L (low voltage).
1. If you install one memory module only, please install it on DDR3_A1.
2. It is not allowed to install a DDR or DDR2 memory module into a
DDR3 slot; otherwise, this motherboard and SO-DIMM may be
damaged.
3. Please make sure to disconnect the power supply before adding or
removing SO-DIMMs or the system components.
4. The SO-DIMM only ts in one correct orientation. It will cause
permanent damage to the motherboard and the SO-DIMM if you force
the SO-DIMM into the slot at incorrect orientation.
Installing a SO-DIMM
Step 1. Align a SO-DIMM on the slot such that the notch on the SO-DIMM
matches the break on the slot.
Step 2. Firmly insert the SO-DIMM into the slot until the retaining clips at both
ends fully snap back in place and the SO-DIMM is properly seated.

13
2.4 Expansion Slots (mini-PCIe, mini-PCIe/mini-SATA and PCI
Express Slots)
There is 1 mini-PCIe slot, 1 mini-PCIe/mini-SATA slot and 1 PCI Express slot on this
motherboard.
mini-PCIe slot:
MINI_PCIE1 (mini-PCIe slot; half size) is used for PCI Express mini
cards.
mini-PCIe/mini-SATA slot:
MINI_SATA1 (mini-PCIe slot/mini-SATA slot; full size) is used for PCI
Express mini cards or mSATA cards. This SATA signal is shared with
SATA2_2 connector.
PCIE slot: PCIE1 (PCIE x1 slot) is used for PCI Express x1 lane width cards.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched o󰀨 or the power cord is unplugged. Please read the
documentation of the expansion card and make necessary hardware
settings for the card before you start the installation.
Step 2. Remove the system unit cover (if your motherboard is already installed
in a chassis).
Step 3. Remove the bracket facing the slot that you intend to use. Keep the
screws for later use.
Step 4. Align the card connector with the slot and press rmly until the card is
completely seated on the slot.
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

14
2.5 Jumpers Setup
The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration shows a 3-pin jumper whose
pin1 and pin2 are “Short” when jumper cap
is placed on these 2 pins.
Clear CMOS Jumper
(CLRCMOS1)
(see p.8, No. 22)
Note: CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the
system parameters to default setup, please turn o󰀨 the computer and unplug
the power cord from the power supply. After waiting for 15 seconds, use a
jumper cap to short pin2 and pin3 on CLRCMOS1 for 5 seconds. However,
please do not clear the CMOS right after you update the BIOS. If you need
to clear the CMOS when you just nish updating the BIOS, you must boot up
the system rst, and then shut it down before you do the clear-CMOS action.
Please be noted that the password, date, time, user default prole and MAC
address will be cleared only if the CMOS battery is removed.

2.6 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!
SATA2 Connectors These two Serial ATA2
(SATA2_1, SATA2_2: see p.8, No. 26) (SATA2) connectors support
SATA data cables for internal
storage devices. The current
SATA2 interface allows up to
3.0 Gb/s data transfer rate.
USB 2.0 Connectors Besides two default USB 2.0
(9-pin USB2_34) ports on the I/O panel, there
(see p.8 No. 29) are two USB 2.0 connectors on
this motherboard. Each USB 2.0
(9-pin USB2_56) connector can support two USB
(see p.8 No. 23) ports.
System Panel Header This header accommodates
(9-pin PANEL1) several system front panel
(see p.8 No. 20) functions.
Connect the power switch, reset switch and system status indicator on the
chassis to this header according to the pin assignments below. Note the
positive and negative pins before connecting the cables.
PWRBTN (Power Switch):
Connect to the power switch on the chassis front panel. You may congure
the way to turn o󰀨 your system using the power switch.
RESET (Reset Switch):
Connect to the reset switch on the chassis front panel. Press the reset
switch to restart the computer if the computer freezes and fails to perform a
normal restart.

PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. The LED
is on when the system is operating. The LED keeps blinking when the sys-
tem is in S1/S3 sleep state. The LED is o󰀨 when the system is in S4 sleep
state or powered o󰀨 (S5).
HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. The LED
is on when the hard drive is reading or writing data.
The front panel design may di󰀨er by chassis. A front panel module mainly
consists of power switch, reset switch, power LED, hard drive activity LED,
speaker and etc. When connecting your chassis front panel module to this
header, make sure the wire assignments and the pin assign-ments are
matched correctly.
3W Audio AMP Output Wafer
(4-pin SPEAKER1)
(see p.8 No. 30)
Front Panel Audio Header This is an interface for front
(9-pin HD_AUDIO1) panel audio cable that allows
(see p.8 No. 34) convenient connection and
control of audio devices.
1. High Denition Audio supports Jack Sensing, but the panel wire on
the chassis must support HDA to function correctly. Please follow the
instruction in our manual and chassis manual to install your system.
2. If you use AC’97 audio panel, please install it to the front panel audio
header as below:
A. Connect Mic_IN (MIC) to MIC2_L.
B. Connect Audio_R (RIN) to OUT2_R and Audio_L (LIN) to OUT2_L.
C. Connect Ground (GND) to Ground (GND).
D. MIC_RET and OUT_RET are for HD audio panel only. You don’t
need to connect them for AC’97 audio panel.
E. To activate the front mic.
Go to the “FrontMic” Tab in the Realtek Control panel. Adjust
“Recording Volume”.
