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
is is an ATX form factor (12'' x 10'', 30.5 cm x 25.4 cm) motherboard. 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 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 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 from the power supply. Failure to do so may cause severe damage to
the motherboard, peripherals, and/or components.
