Safety Instructions
Before You Begin
Before handling your MBATX-945G-VGA board, read the instructions and safety
guidelines on the following pages to prevent damage to the product and to ensure your
own personal safety. Refer to the “Advisories” section in the Preface for advisory
conventions used in this user’s guide, including the distinction between Warnings,
Cautions, Important Notes, and Notes.
Always use caution when handling or operating a computer. Only qualified,
experienced, authorized electronics service personnel should access the interior
of a computer. The power supplies produce high voltages and energy hazards,
which can cause bodily harm.
If you have any problems or questions about the unit, please contact Kontron
Post-Sales Technical Support.
WARNING
High voltages are present inside a computer chassis when the
unit’s power cord is plugged into an electrical outlet. Turn off
system power, turn off the power supply, and then disconnect
the power cord from its source before removing the chassis
cover. Turning off the system power switch does not remove
power to components.
MBATX-945G-VGA User’s Guide page 7
When Working Inside a Computer
Before taking covers off a computer, perform the following steps:
1) Turn off the computer and any peripherals.
2) Disconnect the computer and peripherals from their power sources or
subsystems to prevent electric shock or system board damage. This does not
apply when hot swapping parts.
3) Follow the guidelines provided in “Preventing Electrostatic Discharge” on the
following page.
4) Disconnect any telephone or telecommunications lines from the computer.
In addition, take note of these safety guidelines when appropriate:
To help avoid possible damage to system boards, wait five seconds after turning
off the computer before removing a component, removing a system board, or
disconnecting a peripheral device from the computer.
When you disconnect a cable, pull on its connector or on its strain-relief loop, not
on the cable itself. Some cables have a connector with locking tabs. If you are
disconnecting this type of cable, press in on the locking tabs before
disconnecting the cable. As you pull connectors apart, keep them evenly aligned
to avoid bending any connector pins. Also, before connecting a cable, make sure
both connectors are correctly oriented and aligned
CAUTION
Do not attempt to service the system yourself. Follow installation
and troubleshooting instructions closely.
page 8 MBATX-945G-VGA User’s Guide
Preventing Electrostatic Discharge
Static electricity can harm system boards. Perform service at an ESD workstation and
follow proper ESD procedure to reduce the risk of damage to components. Kontron
strongly encourages you to follow proper ESD procedure, which can include wrist straps
and smocks, when servicing equipment.
You can also take the following steps to prevent damage from electrostatic discharge
(ESD):
When unpacking a static-sensitive component from its shipping carton, do not
remove the component’s antistatic packing material until you are ready to install
the component in a computer. Just before unwrapping the antistatic packaging,
be sure you are at an ESD workstation or grounded. This will discharge any
static electricity that may have built up in your body.
When transporting a sensitive component, first place it in an antistatic container
or packaging.
Handle all sensitive components at an ESD workstation. If possible, use antistatic
floor pads and workbench pads.
Handle components and boards with care. Don’t touch the components or
contacts on a board. Hold a board by its edges or by its metal mounting bracket.
Do not handle or store system boards near strong electrostatic, electromagnetic,
magnetic, or radioactive fields.

Special Features of the System Board
Watchdog Timer
The Watchdog Timer function allows your application to regularly “clear” the system at
the set time interval. If the system hangs or fails to function, it will reset at the set time
interval so that your system will continue to operate
PCI Express

system boot up. Once the CPU’s temperature exceeded the temperature limit predefined by the CPU, the system will automatically shutdown. This preventive measure
has been added to protect the CPU from damage and insure a safe computing
environment.
DDR2
DDR2 is a higher performance DDR technology whose data transfer rate delivers
bandwidth of 4.3 GB per second and beyond. That is twice the speed of the
conventional DDR without increasing its power consumption. DDR2 SDRAM modules
work at 1.8V supply compared to 2.6V memory voltage for DDR modules. DDR2 also
incorporates new innovations such as the On-Die Termination (ODT) as well as larger
4-bit pre-fetch against DDR which fetches 2 bits per clock cycle.
S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital audio signals to a
device without having to be converted first to an analog format. This prevents the quality
of the audio signal from degrading whenever it is converted to analog. S/PDIF is usually
found on digital audio equipment such as a DAT machine or audio processing device.
The S/PDIF connector on the system board sends surround sound and 3D audio signal
outputs to amplifiers and speakers and to digital recording devices like CD recorders.
Serial ATA Interface
Serial ATA is a storage interface that is compliant with SATA 1.0 specification. With
speed of up to 3Gb/s, it improves hard drive performance faster than the standard
parallel ATA whose data transfer rate is 100MB/s.
IrDA Interface
The system board is equipped with an IrDA connector for wireless connectivity between
your computer and peripheral devices. The IRDA (Infrared Data Association)
specification supports data transfers of 115K baud at a distance of 1 meter.
USB Ports
The system board supports USB 2.0 and USB 1.1 ports. USB 1.1 supports
12Mb/second bandwidth while USB 2.0 supports 480Mb/second bandwidth providing a
marked improvement in device transfer speeds between your computer and a wide

Power Connectors
We recommend that you use a power supply that complies with the ATX12V Power
Supply Design Guide Version 1.1. An ATX12V power supply has a standard 24-pin ATX
main power connector and a 4-pin +12V power connector that must be inserted onto
CN8 and P1 connectors respectively.
The 4-pin +12V power connector enables the delivery of more +12VDC current to the
processor’s Voltage Regulator Module (VRM).
The system board requires a minimum of 300 Watt power supply to operate. Your
system configuration (CPU power, amount of memory, add-in cards, peripherals, etc.)
may exceed the minimum power requirement. To ensure that adequate power is
provided, we strongly recommend that you use a minimum of 400 Watt (or greater)
power supply.

Advanced Chipset Features
The settings on the screen are for reference only. Your version may not be identical to this one.
This section gives you functions to configure the system based on the specific features
of the chipset. The chipset manages bus speeds and access to system memory
resources. These items should not be altered unless necessary. The default
settings have been chosen because they provide the best operating conditions for your
system.
The only time you might consider making any changes would be if you discovered some
incompatibility or that data was being lost while using your system.
DRAM Timing Selectable
This field is used to select the timing of the DRAM.
By SPD The EEPROM on a DIMM has SPD (Serial Presence Detect) data
structure that stores information about the module such as the memory
type, memory size, memory speed, etc. When this option is selected, the
system will run according to the information in the EEPROM. This option is
the default setting because it provides the most stable condition for the
system. The “CAS Latency Time” to “System Memory Frequency” fields
will show the default settings by SPD.
Manual If you want better performance for your system other than the one “by
SPD”, select “Manual” then select the best option in the “CAS Latency
Time” to “System Memory Frequency” fields.

SLP_S4# Assertion Width
The options are 1 to 2 Sec., 2 to 3 Sec., 3 to 4 Sec. and 4 to 5 Sec.
System BIOS Cacheable
When this field is enabled, accesses to the system BIOS ROM addressed at F0000HFFFFFH are cached, provided that the cache controller is enabled. The larger the range
of the Cache RAM, the higher the efficiency of the system.
Video BIOS Cacheable
As with caching the system BIOS, enabling the Video BIOS cache will allow access to
video BIOS addressed at C0000H to C7FFFH to be cached, if the cache controller is
also enabled. The larger the range of the Cache RAM, the faster the video performance.
Memory Hole At 15M-16M
In order to improve system performance, certain space in memory can be reserved for
ISA cards. This memory must be mapped into the memory space below 16MB. When
enabled, the CPU assumes the 15-16MB memory range is allocated to the hidden ISA
address range instead of the actual system DRAM. When disabled, the CPU assumes
the 15-16MB address range actually contains DRAM memory. If more than 16MB of
system memory is installed, this field must be disabled to provide contiguous system
memory.
