1.3 Unique Features

ASRock Rack Instant Flash is a BIOS ash utility embedded in Flash ROM. is con-

venient BIOS update tool allows you to update system BIOS without entering operat-

ing systems rst 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 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.

Chapter 2 Installation

This i s a Mini IT X form f ac tor (6.7' ' x 6.7'', 17.0 cm x 17.0 cm) mot herb oa rd. 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 c ord before installing or re moving the mothe rboard. Failure
to do so may cause physical injurie s to you and d amages 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 insta ll motherboard components or

change 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 a

grounded wrist strap or touch a safety grounded object before you handle the compo-

nents.

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 o or the
power cord is detached f rom the power supply. Failure to d o so may cau se severe damage to
the motherboard, peripherals, and/or components.

English

2.3 Installing the CPU and Heatsink

1. Before you insert the CPU into the socket, please check if the PnP cap is on the socket ,
if the CPU sur face is unclean, or if there are any bent pins in the socket. Do not force to
inser t the CPU into the socket if above situation is found. Oth erwise, the CPU will be
seriously damaged.

2. Unplug all power c ables before in stalling the CPU.

EPC621D4I-2M / EPC621D6I

1. Before you installed the heatsink , you need to spray thermal interface material between the CPU
and the heatsink to improve heat dissipation.

2. Illustration in this documentation are examples only. Heatsink or fan cooler type may dier.
