Englishhis is an ATX form factor motherboard. Before you install the motherboard, s tudy
the coniguration of your chassis to ensure that the motherboard its into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard com ponents
or change any motherboard settings.
• Make sure to unplug the power cord before installing or removing the motherb oard
components. Failure to do so may cause physical injuries and damages to mothe rboard
components.
• In order to avoid damage from static electricity to the motherboard’s comp onents,
NEVER place your motherboard directly on a carpet. Also remember to use a grounde d
wrist strap or touch a safety grounded object before you handle the components.
• Hold components by the edges and do not touch the ICs.
• Whenever you uninstall any components, place them on a grounded anti-static pa d or
in the bag that comes with the components.
• When placing screws to secure the motherboard to the chassis, please do not ove r-
tighten the screws! Doing so may damage the motherboard.Chapter 2 Installation

the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper
is “Open”. he illustration shows a 3-pin jumper whose pin1 and pin2 are “Short”
when a jumper cap is placed on these 2 pins.
Clear CMOS Jumper
(CLRMOS1)
(see p.7, No. 19)
CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system
parameters to default setup, please turn of the computer and unplug the powe r
cord from the power supply. Ater 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 ater you update the BIOS. If you need to clear the CMOS when you
just inish updating the BIOS, you must boot up the system irst, and then shut it
down before you do the clear-CMOS action. Please be noted that the password,
date, time, and user default proile will be cleared only if the CMOS battery is
removed.Clear CMOS Default
he Clear CMOS Switch has the same function as the Clear CMOS jumper.

BIOS Selection Jumper
(BIOS_SEL1)
(see p.7, No. 18)
his motherboard has two BIOS onboard, a main BIOS (BIOS_A) and a backup
BIOS (BIOS_B), which enhances protection for the safety and stability of you r
system. Normally, the system works on the main BIOS. However, if the main BIOS
is corrupted or damaged, please use a jumper cap to short pin2 and pin3, then
the backup BIOS will take over on the next system boot. Ater that, use “Secure
Backup UEFI“ in BIOS setup utility to copy the BIOS ile to the main BIOS to
ensure normal system operation. For the sake of system safety, users cannot
update the backup BIOS manually. Users may refer to the BIOS LED (BIOS_A_
LED or BIOS_B_LED) to identify which BIOS is activated currently.Backup BIOS Default

3.4 Enabling USB Ports for Windows® 7 Installation
Intel® Braswell and Skylake has removed their support for the Enhanced Host
Controller Interface (EHCI – USB2.0) and only kept the eXtensible Host Control ler
Interface (XHCI – USB3.0). Due to that fact that XHCI is not included in the
Windows 7 inbox drivers, users may ind it diicult to install Windows 7 operati ng
system because the USB ports on their motherboard won’t work. In order for the
USB ports to function properly, please create a Windows® 7 installation disk w ith
the Intel® USB 3.0 eXtensible Host Controller (xHCI) drivers packed into the I SO
ile.
Requirements
• A Windows® 7 installation disk or USB drive
• USB 3.0 drivers (included in the ASRock Support CD or website)
• A Windows® PC
• Win7 USB Patcher (included in the ASRock Support CD or website)
Scenarios
You have an ODD and PS/2 ports:
If there is an optical disc drive, PS/2 ports and PS/2 Keyboard or mouse on your computer,
you can skip the instructions below and go ahead to install Windows® 7 OS.
You only have an ODD (For Intel Skylake platforms only) :
If there is an optical disc drive but no PS/2 ports on your computer, please enable the “PS /2
Simulator” option in UEFI SETUP UTILITY > Advanced > USB Coniguration , which
allows the USB port to function as a PS/2 port, and then you can install the Windows® 7
OS. Please set PS/S Simulator back to disabled ater the installation.
You’ve got nothing:
If you do not have an optical disc drive, please ind another computer and follow the
instructions below to create a new ISO ile with the “Win7 USB Patcher”. hen use the n ew
patched Windows® 7 installation USB drive to install Windows® 7 OS.

54
EnglishInstructions
Step 1
Insert the Windows® 7 installation disk or USB drive to your system.
Step 2
Extract the tool (Win7 USB Patcher) and launch it.
Step 3
Select the “Win7 Folder” from Step1 by clicking the red circle as shown as the pic ture
below.
Step 4
Select the “USB Driver Folder” by clicking the red circle as shown as the picture be low.
If you are using ASRock’s Support CD for the USB 3.0 driver, please select your CD-RO M.

55

Step 5
Select where to save the ISO ile by pressing the red circle as shown as the picture bel ow.
Step 6
If you want to burn the patched image to a CD, please chec k “Burn Image” and select “Target
Device to Burn”. If not, the patched ISO image will be exported to the destinat ion selected
in Step5. hen Press “Start” to proceed.
Step 7
Now you are able to install Windows® 7 on Braswell or Skylake with the new burned CD.
Or please use the patched ISO image to make an OS USB drive to install the OS.
