1.3 Unique Features
ASRock Instant Flash
ASRock Instant Flash is a BIOS ash utility embedded
in Flash ROM. This convenient BIOS update tool allows
you to update system BIOS without entering operating
systems rst like MS-DOS or Windows®. With this util-
ity, you can press the <F6> key during the POST or the
<F2> key to enter into the BIOS setup menu to access
ASRock Instant Flash. Just launch this tool and save
the new BIOS le to your USB ash drive, oppy disk or
hard drive, then you can update your BIOS only in a few
clicks without preparing an additional oppy diskette or
other complicated ash utility. Please be noted that the
USB ash drive or hard drive must use FAT32/16/12 le
system.
ASRock Crashless BIOS
ASRock Crashless BIOS allows users to update their
BIOS without fear of failing. If power loss occurs during
the BIOS update process, ASRock Crashless BIOS will
automatically finish the BIOS update procedure after
regaining power. Please note that BIOS files need to
be placed in the root directory of your USB disk. Only
USB2.0 ports support this feature.

Chapter 2: Installation
This is a Mini-ITX form factor motherboard. Before you install the mother-
board, study the conguration of your chassis to ensure that the mother-
board ts into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard com-
ponents or change any motherboard settings.
1. 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 com-
ponents.
2. In order to avoid damage from static electricity to the moth-
erboard’s components, NEVER place your motherboard
directly on a carpet. Also remember to use a grounded 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 components, place them on a
grounded anti-static pad or in the bag that comes with the
components.
5. When placing screws to secure the motherboard to the
chassis, please do not over-tighten the screws! Doing so
may damage the motherboard.

13
2.1 Installing Memory Modules (DIMM)
This motherboard provides two 204-pin DDR3 (Double Data Rate 3) SO-
DIMM slots.
Step 1. Align a DIMM on the slot such that the notch on the DIMM
matches the break on the slot.
The DIMM only ts in one correct orientation. It will cause per-
manent damage to the motherboard and the DIMM if you force
the DIMM into the slot at incorrect orientation.
Step 2. Firmly insert the DIMM into the slot until the retaining clips at both
ends fully snap back in place and the DIMM is properly seated.

14
2.2 Expansion Slots (PCI Express Slots)
There is 1 mini PCI Express slot on this motherboard.
mini-PCIE Slots: mini_PCIE1 is used for mini PCIE cards.
Installing an Expansion Card
Step 1. Before installing an expansion card, please make sure that the
power supply is switched off 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. Align the card connector with the slot and press rmly until the
card is completely seated on the slot.

15
Serial ATA2 Connectors
(SATAII_1: see p.10, No. 13)
(SATAII_2: see p.10, No. 11)
SATAII_2 SATAII_1
These two Serial ATA2
(SATA2) connectors sup-
port SATA data cables for
internal storage devices.
The current SATA2 interface
allows up to 3.0 Gb/s data
transfer rate.
2.3 Installing Serial SATA / SATA2 Hard Disks
STEP 1: Connect the SATA power cable to the hard disk.
STEP 2: Connect one end of the SATA data cable to the hard disk.
STEP 3:Connect the other end of the SATA data cable to the mother-
board’s SATA2 connectors.

2.5 Installing the System Panel
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 off 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 off when the system is in S4 sleep
state or powered off (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 differ 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 assignments are
matched correctly.
The white wires are negative (Connect to - or GND pins), while the
colored ones are positive.

2.6 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT
place jumper caps over these headers and connectors. Plac-
ing jumper caps over the headers and connectors will cause
permanent damage to the motherboard!
USB 2.0 Headers
(8-pin USB4_5)
(see p.10, No. 28)
(4-pin USB6)
(see p.10, No. 29)
Besides four default USB 2.0
ports on the I/O panel, there
are two USB 2.0 headers on
this motherboard. The USB
2.0 headers can support
three USB 2.0 ports.
This is an interface for print
port cable that allows conve-
nient connection of printer
devices.
