NOTE: Please refer to our website for the latest specifications.

This motherboard supports Wake from on Board LAN. To use this function, please makesure that the “Wake on Magic Packet from power off state” is enabled in Device Manager> Intel® Ethernet Connection > Power Management. And the “PCI Devices Power On” isenabled in UEFI SETUP UTILITY > Advanced > ACPI Configuration. After that, onboard
LAN1&2 can wake up S5 under OS.

EnglishIf you install Intel® LAN utility or Marvell SATA utility, this motherboard may fail Windows® Hardware Quality Lab (WHQL) certification tests. If you install the drivers only, it
will pass the WHQL tests.

1.3 Unique Features
ASRock Rack Instant Flash is a BIOS flash utility embedded in Flash ROM. This convenient BIOS update tool allows you to update system BIOS without entering operating systems first like MS-DOS or Windows®. With this utility, you can press the <F6>
key during the POST or the <F2> key to enter into the BIOS setup menu to access
ASRock Rack Instant Flash. Just launch this tool and save the new BIOS file to yourUSB flash drive, floppy disk or hard drive, then you can update your BIOS only in a
few clicks without preparing an additional floppy diskette or other complicated flash
utility. Please be noted that the USB flash drive or hard drive must use FAT32/16/12
file system.

Chapter 2 Installation
This is a mini ITX form factor (6.7'' x 6.7'', 17.02 cm x 17.02 cm) motherboard. Before
you install the motherboard, study the configuration of your chassis to ensure that themotherboard fits 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 indicated by circles 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 orchange any motherboard settings.
1. Unplug the power cord from the wall socket before touching any components.
2. To avoid damaging the motherboard’s components due to static electricity, NEVER
place your motherboard directly on the carpet or the like. Also remember to use agrounded wrist strap or touch a safety grounded object before you handle the components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded anti-static pad or in
the bag that comes with the component.
5. When placing screws into the screw holes to secure the motherboard to the chassis,
please do not over-tighten the screws! Doing so may damage the motherboard.
Before you install or remove any component, ensure that the power is switched off or the
power cord is detached from the power supply. Failure to do so may cause severe damage tothe motherboard, peripherals, and/or components.

2.3 Installing the CPU
1. Before you insert the 1151-Pin CPU into the socket, please check if the PnP cap is on thesocket, if the CPU surface is unclean, or if there are any bent pins in the socket. Do notforce to insert the CPU into the socket if above situation is found. Otherwise, the CPU
will be seriously damaged.
2. Unplug all power cables before installing the CPU.

EnglishTo install the drivers to your system, please insert the support CD to your opticaldrive first. Then, the drivers compatible to your system can be auto-detected and listedon the support CD driver page. Please follow the order from top to bottom to installthose required drivers. Therefore, the drivers you install can work properly.

2.11 Dual LAN and Teaming Operation Guide
Dual LAN with Teaming enabled on this motherboard allows two single
connections to act as one single connection for twice the transmission bandwidth,
making data transmission more effective and improving the quality of transmissionof distant images. Fault tolerance on the dual LAN network prevents network
downtime by transferring the workload from a failed port to a working port.
The speed of transmission is subject to the actual network environment or status even with
Teaming enabled.

Before setting up Teaming, please make sure whether your Switch (or Router)supports Teaming (IEEE 802.3ad Link Aggregation). You can specify a preferred
adapter in Intel PROSet. Under normal conditions, the Primary adapter handles all
non-TCP/IP traffic. The Secondary adapter will receive fallback traffic if the primaryfails. If the Preferred Primary adapter fails, but is later restored to an active status,
control is automatically switched back to the Preferred Primary adapter.
Step 1
From Device Manager, open the properties of a team.
Step 2
Click the Settings tab.
Step 3
Click the Modify Team button.
Step 4
Select the adapter you want to be the primary adapter and click the Set Primary
button.
If you do not specify a preferred primary adapter, the software will choose anadapter of the highest capability (model and speed) to act as the default primary. If
a failover occurs, another adapter becomes the primary. The adapter will, however,rejoin the team as a non-primary.

3.1 Introduction
Th is section explains how to use the UEFI SETUP UTILITY to configure your system. The
UEFI chip on the motherboard stores the UEFI SETUP UTILITY. You may run the UEFISETUP UTILITY when you start up the computer. Please press <F2> or <Del> during thePower-On-Self-Test (POST) to enter the UEFI SETUP UTILITY; otherwise, POST willcontinue with its test routines.
If you wish to enter the UEFI SETUP UTILITY after POST, restart the system by pressing<Ctrl> + <Alt> + <Delete>, or by pressing the reset button on the system chassis. You may
also restart by turning the system off and then back on.
Because the UEFI software is constantly being updated, the following UEFI setup screensand descriptions are for reference purpose only, and they may not exactly match what you
