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.

13
2.3 Installation of Memory Modules (SO-DIMM)
IMB-1003 motherboard provides two 260-pin DDR4 (Double Data Rate 4) SO-DIMM
slots, and supports Dual Channel Memory Technology.
1. If you install one memory module only, please install it on DDR4_A1.
2. It is not allowed to install a DDR, DDR2 or DDR3 memory module into
a DDR4 slot; otherwise, this motherboard and SO-DIMM may be
damaged.
2. Please make sure to disconnect the power supply before adding or
removing SO-DIMMs or the system components.
3. 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.

14
2.4 Expansion Slots (PCI Express, M.2 and SIM Sockets)
There is 1 PCI Express, 3 M.2 and 1 SIM sockets on this motherboard.

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 Open: Normal
(2-pin CLRMOS2)
Short: Auto Clear CMOS When AC
(see p.8, No. 21) Power On
Note: CLRMOS2 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 o󰀨 the computer and unplug the power cord, then use a jumper
cap to short the pins on CLRMOS2 for 3 seconds. Please remember to re-
move the jumper cap after clearing the CMOS. 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.
Clear CMOS Jumper 1-2: Normal
(3-pin CLRMOS1) 2-3: Clear CMOS
(see p.8, No. 21)
Note: CLRMOS1 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 CLRMOS1 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.
Digital Input / Output Power Select (JGPIO_PWR) 1-2: +12V

Note: Please set to 1-2 when adjusting brightness by Brightness Control bar
under OS.
Please set to 2-3 when adjusting brightness by BLT_VOL1.

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!
SATA3 Connectors These two Serial ATA3
(SATA3_1: see p.8, No. 6) (SATA3) connectors support
(SATA3_2: see p.8, No. 41 (shared with M2_M1)) SATA data cables for internal
storage devices. The current
SATA3 interface allows up to
6.0 Gb/s data transfer rate.
USB 2.0 Connectors There are two USB 2.0
(9-pin USB2_2_3, USB2_5_6) connectors and one USB 2.0
(see p.8 No. 5) port on this motherboard.
USB 2.0 Port
(USB2_4)
(see p.8 No. 8)
System Panel Header This header accommodates
(9-pin PANEL1) several system front panel
(see p.8 No. 25) 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 sleep state. The LED is o󰀨 when the system is in S3/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. 39)
Front Panel Audio Header This is an interface for front
(9-pin HD_AUDIO1) panel audio cable that allows
(see p.8 No. 40) 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”.

Though this motherboard provides 4-Pin CPU fan (Quiet Fan) support, the 3-Pin
CPU fan still can work successfully even without the fan speed control function.
If you plan to connect the 3-Pin CPU fan to the CPU fan connector on this
motherboard, please connect it to Pin 1-3.

CPU Fan Connector Please connect the CPU fan
(4-pin CPU_FAN1) cable to the connector and
(see p.8 No. 11) match the black wire to the
ground pin.
