and features to meet business needs. It provides excellent video and 3D graphics with outstanding graphics responsiveness. These enhancements deliver the performance and compatibility needed for today’s and tomorrow’s business applications. Supports 1 x DDI (HDMI/DVI/
DP++) and 1 x LVDS/eDP interfaces for display outputs.
• Serial ATA
Serial ATA is a storage interface that is compliant with SATA 1.0a specification. With speed of
up to 6Gb/s (SATA 3.0), it improves hard drive performance faster than the standard parallel
ATA whose data transfer rate is 100MB/s.
• Gigabit LAN
The Intel® I210AT Gigabit LAN controller or the Intel® I210IT Gigabit LAN controller supports
up to 1Gbps data transmission.
• USB
The system board supports the new USB 3.0. It is capable of running at a maximum transmission speed of up to 5 Gbit/s (625 MB/s) and is faster than USB 2.0 (480 Mbit/s, or 60 MB/s)
and USB 1.1 (12Mb/s). USB 3.0 reduces the time required for data transmission, reduces
power consumption, and is backward compatible with USB 2.0. It is a marked improvement in
device transfer speeds between your computer and a wide range of simultaneously accessible
external Plug and Play peripherals.

<Enter>
Press <Enter> to enter the highlighted

The BIOS is a program that takes care of the basic level of communication between the CPU
and peripherals. It contains codes for various advanced features found in this system board.
The BIOS allows you to configure the system and save the configuration in a battery-backed
CMOS so that the data retains even when the power is off. In general, the information stored
in the CMOS RAM of the EEPROM will stay unchanged unless a configuration change has been
made such as a hard drive replaced or a device added.
It is possible that the CMOS battery will fail causing CMOS data loss. If this happens, you need
to install a new CMOS battery and reconfigure the BIOS settings.
Note:
The BIOS is constantly updated to improve the performance of the system board;
therefore the BIOS screens in this chapter may not appear the same as the actual
one. These screens are for reference purpose only.
Entering the BIOS Setup Utility
Scroll Bar
The BIOS Setup Utility can only be operated from the keyboard and all commands are keyboard commands. The commands are available at the right side of each setup screen.
When a scroll bar appears to the right of the setup screen, it indicates that there are more
available fields not shown on the screen. Use the up and down arrow keys to scroll through all
the available fields.
The BIOS Setup Utility does not require an operating system to run. After you power up the
system, the BIOS message appears on the screen and the memory count begins. After the
memory test, the message “Press DEL to run setup” will appear on the screen. If the message
disappears before you respond, restart the system or press the “Reset” button. You may also
restart the system by pressing the <Ctrl> <Alt> and <Del> keys simultaneously.
Submenu
When “” appears on the left of a particular field, it indicates that a submenu which contains
additional options are available for that field. To display the submenu, move the highlight to
that field and press <Enter>.

Updating the BIOS
Notice: BIOS SPI ROM
To update the BIOS, you will need the new BIOS file and a flash utility. Please contact technical support or your sales representative for the files. For updating AMI BIOS in UEFI mode,
you may refer to the how-to-video at https://www.dfi.com/Knowledge/Video/5 .
1. The Intel® Management Engine has already been integrated into this system board. Due to
the safety concerns, the BIOS (SPI ROM) chip cannot be removed from this system board
and used on another system board of the same model.
2. The BIOS (SPI ROM) on this system board must be the original equipment from the factory
and cannot be used to replace one which has been utilized on other system boards.
3. If you do not follow the methods above, the Intel® Management Engine will not be
updated and will cease to be effective.
Note:
a. You can take advantage of flash tools to update the default configuration of the
BIOS (SPI ROM) to the latest version anytime.
b. When the BIOS IC needs to be replaced, you have to populate it properly onto the
system board after the EEPROM programmer has been burned and follow the
technical person's instructions to confirm that the MAC address should be burned
or not.

Appendix C - Troubleshooting
The picture seems to be constantly moving.
1. The monitor has lost its vertical sync. Adjust the monitor’s vertical sync.
Troubleshooting Checklist
2. Move away any objects, such as another monitor or fan, that may be creating a magnetic
field around the display.
This chapter of the manual is designed to help you with problems that you may encounter
with your personal computer. To efficiently troubleshoot your system, treat each problem individually. This is to ensure an accurate diagnosis of the problem in case a problem has multiple
causes.
3. Make sure your video card’s output frequencies are supported by this monitor.
The screen seems to be constantly wavering.
Some of the most common things to check when you encounter problems while using your
system are listed below.
1. The power switch of each peripheral device is turned on.
1. If the monitor is close to another monitor, the adjacent monitor may need to be turned off.
Fluorescent lights adjacent to the monitor may also cause screen wavering.
2. All cables and power cords are tightly connected.
Power Supply
3. The electrical outlet to which your peripheral devices connected is working. Test the outlet
by plugging in a lamp or other electrical device.
When the computer is turned on, nothing happens.
4. The monitor is turned on.
1. Check that one end of the AC power cord is plugged into a live outlet and the other end
properly plugged into the back of the system.
5. The display’s brightness and contrast controls are adjusted properly.
2. Make sure that the voltage selection switch on the back panel is set for the correct type of
voltage you are using.
6. All add-in boards in the expansion slots are seated securely.
3. The power cord may have a “short” or “open”. Inspect the cord and install a new one if
necessary.
7. Any add-in board you have installed is designed for your system and is set up correctly.
Monitor/Display
If the display screen remains dark after the system is turned on:
1. Make sure that the monitor’s power switch is on.
2. Check that one end of the monitor’s power cord is properly attached to the monitor and the
other end is plugged into a working AC outlet. If necessary, try another outlet.
3. Check that the video input cable is properly attached to the monitor and the system’s
display adapter.
4. Adjust the brightness of the display by turning the monitor’s brightness control knob.

Hard Drive
System Board
Hard disk failure.
1. Make sure the add-in card is seated securely in the expansion slot. If the add-in card is
loose, power off the system, re-install the card and power up the system.
1. Make sure the correct drive type for the hard disk drive has been entered in the BIOS.
2. Check the jumper settings to ensure that the jumpers are properly set.
2. If the system is configured with two hard drives, make sure the bootable (first) hard drive
is configured as Master and the second hard drive is configured as Slave. The master hard
drive must have an active/bootable partition.
3. Verify that all memory modules are seated securely into the memory sockets.
4. Make sure the memory modules are in the correct locations.
Excessively long formatting period.
5. If the board fails to function, place the board on a flat surface and seat all socketed components. Gently press each component into the socket.
If your hard drive takes an excessively long period of time to format, it is likely a cable connection problem. However, if your hard drive has a large capacity, it will take a longer time to
format.
6. If you made changes to the BIOS settings, re-enter setup and load the BIOS defaults.
Serial Port
The serial device (modem, printer) doesn’t output anything or is outputting garbled
characters.
1. Make sure that the serial device’s power is turned on and that the device is on-line.
2. Verify that the device is plugged into the correct serial port on the rear of the computer.
3. Verify that the attached serial device works by attaching it to a serial port that is working and configured correctly. If the serial device does not work, either the cable or the serial
device has a problem. If the serial device works, the problem may be due to the onboard I/O
or the address setting.
4. Make sure the COM settings and I/O address are configured correctly.
Keyboard
Nothing happens when a key on the keyboard was pressed.
1. Make sure the keyboard is properly connected.
2. Make sure there are no objects resting on the keyboard and that no keys are pressed during the booting process.
