Motherboard information
2.1
Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
CAUTION!
•
Unplug the power cord from the wall socket before touching any
component.
•
Before handling components, use a grounded wrist strap or touch a safely
grounded object or a metal object, such as the power supply case, to avoid
damaging them due to static electricity.
•
Hold components by the edges to avoid touching the ICs on them.
•
Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.
•
Before you install or remove any component, always remove the AC power
by unplugging the power cord from the power outlet. Failure to do so may
cause severe damage to the motherboard, peripherals, or components.
Standby Power LED
The motherboard comes with a standby power LED that lights up to indicate that
the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you
should shut down the system and unplug the power cable before removing or
plugging in any motherboard component. The illustration below shows the location
of the onboard LED.

Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA1150 socket designed for
the Intel® 4th Generation Core™ i7 / Core™ i5 / Core™ i3, Pentium® / Celeron®
processors.
EMB-H81B CPU socket LGA1150
IMPORTANT: Unplug all power cables before installing the CPU.
CAUTION!
2-6
•
Upon purchase of the motherboard, ensure that the PnP cap is on
the socket and the socket contacts are not bent. Contact your retailer
immediately if the PnP cap is missing, or if you see any damage to the
PnP cap/socket contacts/motherboard components. The manufacturer will
shoulder the cost of repair only if the damage is shipment/transit-related.
•
Keep the cap after installing the motherboard. The manufacturer will
process Return Merchandise Authorization (RMA) requests only if the
motherboard comes with the cap on the LGA1150 socket.
•
The product warranty does not cover damage to the socket contacts
resulting from incorrect CPU installation/removal, or misplacement/loss/
incorrect removal of the PnP cap.

System memory
This motherboard comes with two Double Data Rate 3 (DDR3) Small Outline Dual Inline
Memory Module (SO-DIMM) sockets. A DDR3 module has the same physical dimensions
as a DDR2 DIMM but is notched differently to prevent installation on a DDR2 DIMM socket.
DDR3 modules are developed for better performance with less power consumption.
The figure below illustrates the location of the DDR3 SO-DIMM sockets:

2.6Jumpers
1.
Clear RTC RAM (CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS.
You can clear the CMOS memory of system setup parameters by erasing
the CMOS RTC RAM data. The onboard button cell battery powers the RAM
data in CMOS, which include system setup information such as system
passwords.

CLRTC
Protected
(Default)
Clear
EMB-H81B Clear RTC RAM
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on
pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS setup
to reenter data.
CAUTION! Except when clearing the RTC RAM, never remove the cap on
CLRTC jumper default position. Removing the cap will cause system boot
failure!
NOTES:
•
If the steps above do not help, remove the onboard battery and move the
jumper again to clear the CMOS RTC RAM data. After clearing the CMOS,
reinstall the battery.
•
You do not need to clear the RTC when the system hangs due to
overclocking. For system failure due to overclocking, use the CPU
Parameter Recall (C.P.R) feature. Shut down and reboot the system so the
BIOS can automatically reset parameter settings to default values.

Power Supply Considerations
CAUTION!
2-26
•
The external DC jack (5.5/2.5mm) is the primary power input connector of
EMB-H81B. However, the desktop board also provides an internal 2 x 2
power connector that can be used in custom-developed systems that have
an internal power supply.
•
There is no isolation circuitry between the external DC jack and the internal
2 x 2 power connector. It is the system integrator’s responsibility to ensure
no more than one power supply unit is or can be attached to the board at
any time and to ensure the external DC jack is covered if the internal 2 x 2 power connector is to be used.
•
Simultaneous connection of both external and internal power supply units
could result in potential damage to the desktop board, power supplies, or
other hardware.
•
System power requirements will depend on actual system configurations
chosen by the integrator, as well as end user expansion preferences. It
is the system integrator’s responsibility to ensure an appropriate power
budget for the system configuration is properly assessed based on the
system-level components chosen.
•
Using an Adjustable Power Unit power source may result in potential
damage to the motherboard, power supplies, or other hardware.

BIOS setup program
Use the BIOS Setup program to update the BIOS or configure its parameters. The
BIOS screens include navigation keys and brief online help to guide you in using
the BIOS Setup program.
Entering BIOS Setup at startup
To enter BIOS Setup at startup:
Press <Delete> during the Power-On Self Test (POST). If you do not press
<Delete>, POST continues with its routine.
Entering BIOS Setup after POST
To enter BIOS Setup after POST:
•
Press <Ctrl>+<Alt>+<Del> simultaneously.
•
Press the reset button on the system chassis.
•
Press the power button to turn the system off then back on. Do this option only
if you failed to enter BIOS Setup using the first two options.
NOTE: Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys
to reboot a running operating system can cause damage to your data or system.
Always shut down the system properly from the operating system.
IMPORTANT:
•
The default BIOS settings for this motherboard apply to most working
conditions and ensures optimal performance. If the system becomes
unstable after changing any BIOS settings, load the default settings to
regain system stability. Select the option Restore Defaults under the Save
& Exit Menu. See section 3.7 Exit Menu.
