Chapter 2 Installation
is is an Micro ATX form factor motherboard. Before you install the motherboard,
study the conguration of your chassis to ensure that the motherboard ts into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
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.
In order to avoid damage from static electricity to the motherboard’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.
Hold components by the edges and do not touch the ICs.
•
Whenever you uninstall any components, place them on a grounded anti-static pad or
•
in the bag that comes with the components.
When placing screws to secure the motherboard to the chassis, please do not over-
•
tighten the screws! Doing so may damage the motherboard.

2.1 Installing the CPU
1. Before you insert the 1150-Pin CPU into the socket, please check if the P nP cap is on the
socket, if the CPU surface is unclean, or if there are any bent pins in the sock et. Do not
force to in sert the CPU into the socket if above situation is found . Otherwise, the CPU
will be seriously damaged.

(see p.1, No. 22)
CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the system
parameters to default setup, please turn o the computer and unplug the power
cord from the power supply. Aer waiting for 15 seconds, use a jumper cap to
short pin2 and pin3 on CLRCMOS1 for 5 seconds. However, please do not clear
the CMOS right aer you update the BIOS. If you need to clear the CMOS when
you just nish updating the BIOS, you must boot up the system rst, and then shut
it down before you do the clear-CMOS action. Please be noted that the password,
date, time, and user default prole will be cleared only if the CMOS battery is
removed.

is motherboard h as two BIOS chips, a p rimary BIOS (BIOS_A) and a backup BIOS (BIOS_
B), which enhances the safety and stability of your system. Normally, the system will work
on the primary BIOS. However, if the primary BIOS is corrupted or damaged, ju st ip the
BIOS Selection Sw itch to “B”, then the backup BIOS will take over on the next system boot.
Aer that, use “Secure Backup U EFI” in the UEFI Setup Utility to duplicate a working copy
of the BIOS les to the primary BIOS to ensure normal system operation. For safety issues,
users are not able to update the backup BIOS manu ally. Users may refer to the BIOS LEDs
(BIOS_ A_LED or BIOS_B_ LED) to identify which BIOS i s currently activated .
