Chapter 2 Software and Utilities Operation
2.1 Auto Driver Installer (ADI)
Optica l drive or driver DVD is no longer needed for driver installation. ASRock
motherboard already has its Ethernet driver prepacked in BIOS ROM. When you nish
installing the operation system, simply use the Auto Driver Installer to download and
install all necessary drivers automatically.
2.1.1 Installing Drivers for the First Time
Follow the instructions to install all necessary drivers via the Auto Driver Installer.
Please note that the Internet access is required during the following procedures.
Step 1
Aer you install the Windows OS, connect your computer to the Internet.
RJ-45 Cable
LAN Port
Modem
Internet
2
AMD X670/B650 Series
Step 2
Boot into the system, and a notication will pop up in the lower right corner of your
screen saying, "Do you want to one-step-install the latest drivers simply from ASRock
Auto Driver Installer?".
Select “Yes” to install Auto Driver Installer.
Select “No” to skip the installation.
1. e Auto Driver Installer will automatically pop up for users to install dr ivers only
when the “Auto Dr iver Installer“ item under the “Tool“ menu in the BIOS is set to
[Enabled]. e item is enabled by default; therefore, for the r st-time users, there i s
no need to change the setting in the BIOS.
2. An available Internet connection is a prerequisite for u sing the Auto Driver Installer. If you boot into the system without Internet, the Auto Dr iver Installe r won’t
appear. Now connect your computer to the Internet, wait a few seconds, and then
the Auto Dr iver Installe r will pop up.
3. If you sele ct “No“ in Step 2 and skip the insta llation, the Auto Driver Installer will
be remove d. If you would like to run the application again, pl ease enable the “Auto
Driver Installe r“ item in the BIOS setting.

Chapter 3 UEFI SETUP UTILITY
3.1 Introduction
ASRock UEFI (Unied Extensible Firmware Interface) is a BIOS utility which oers twea k-
friendly options in an advanced viewing interface. e UEFI system works with a USB
mouse and oers users a faster, sleeker experience.
is BIOS utility can perform the Power-On Self-Test (POST) during system startup,
record hardware parameters of the system, load operating system, and so on. e battery on
the motherboard supplies the power needed to the CMOS when the system power is turned
o, and the values congured in the UEFI utility are kept in the CMOS.
Please note that inadequate BIOS settings may cause system instability, mulfunction or
boot failure. We strongly recommend that you do not alter the UEFI default congurations
or change the settings only with the assistance of a trained service person.
If the system becomes unstable or fails to boot aer you change the setting, try to clear
the CMOS values and reset the board to default values. See your motherboard manual for
instructions.
3.1.1 Entering BIOS Setup
You may run the UEFI SETUP UTILITY by pressing <F2> or <Del> right aer you power
on the computer; otherwise, the Power-On-Self-Test (POST) will continue with its test
routines. If you wish to enter the UEFI SETUP UTILITY aer POST, restart the system by
pressing <Ctl> + <Alt> + <Delete>, or by pressing the reset button on the system chassis.
You may also restart by turning the system o and then back on.
is setup guide explains how to use the UEFI SETUP UTILITY to congure all the
supported system. e screenshots in this manual are for reference only. UEFI Settings and
options may vary owing to dierent BIOS release versions or CPU installed. Please refer to
the actual BIOS version of the motherboard you purchased for detailed screens, settings
and options.

3.1.2 UEFI Menu Bar
e top of the screen has a menu bar with the following selections:

26
Please realize that there is a certain risk involved with overclocking, including
adjusting the setting in the BIOS, applying Untied Overclo cking Technology, or using
third-party overclocking tools. Overclocking may aect your system’s stability, or
even cause damage to the components and devices of your system. It should be done
at your own risk and expense. We are not responsible for possible damage caused b y
overclocking.
