ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

Chapter 4
AMI BIOS Setup Utility
The AMI UEFI BIOS provides users with a built-in setup program to modify basic system
configuration. All configured parameters are stored in a flash chip to save the setup information
whenever the power is turned off. This chapter provides users with detailed description about
how to set up basic system configuration through the AMI BIOS setup utility.
4.1 Starting
To enter the setup screens, follow the steps below:
1. Turn on the computer and press the <Del> key immediately.
2. After you press the <Del> key, the main BIOS setup menu displays. You can access the
other setup screens from the main BIOS setup menu, such as the Advanced and Chipset
menus.
Note
If your computer cannot boot after making and saving system changes with BIOS
setup, you can restore BIOS optimal defaults by setting JP1 (see section 2.3.2).
It is strongly recommended that you should avoid changing the chipset’s defaults. Both AMI
and your system manufacturer have carefully set up these defaults that provide the best
performance and reliability.
4.2 Navigation Keys
The BIOS setup/utility uses a key-based navigation system called hot keys. Most of the BIOS
setup utility hot keys can be used at any time during the setup navigation process. These keys
include <F1>, <F2>, <Enter>, <ESC>, <Arrow> keys, and so on.
Note
Some of the navigation keys differ from one screen to another.

BIOS Flash Utility
The BIOS Flash utility is a new helpful function in BIOS setup program. With this function you
can easily update system BIOS without having to enter operating system. In this appendix you
may learn how to do it in just a few steps. Please read and follow the instructions below
carefully.
1. In your USB flash drive, create a new folder and name it “Axiomtek”, see figure below.
2. Copy BIOS ROM file (e.g. CAPA313.005) to “Axiomtek” folder.
3. Insert the USB flash drive to your system.
4. Enter BIOS setup menu and go to Advanced\Utility Configuration. Select BIOS Flash
Utility and press <Enter>.

5. BIOS automatically detect all USB drive(s) attached to the system. In this example only
one USB drive is attached to the system. That’s why, you can see only one device is
displayed in figure below.
6. Select the USB drive containing BIOS ROM file you want to update using the <> or
<> key. Then press <Enter> to get into “Axiomtek” folder.
7. Now you can see the BIOS ROM file on the screen, press <Enter> to select.
8. Select Start to flash system BIOS option to begin updating procedure.
