1.3Glossary of Terms and Acronyms
This section defines conventions and terminology used throughout this document.
AggressorA network that transmits a coupled signal to another network.
Anti-etchAny plane-split, void or cutout in a VCC or GND plane.
Assisted Gunning Transceiver Logic+
The front-side bus uses a bus technology called AGTL+, or
Assisted Gunning Transceiver Logic. AGTL+ buffers are opendrain, and require pull-up resistors to provide the high logic level
and termination. AGTL+ output buffers differ from GTL+ buffers
with the addition of an active pMOS pull-up transistor to assist
the pull-up resistors during the first clock of a low-to-high
voltage transition.
Asynchronous GTL+ The processor does not utilize CMOS voltage levels on any
signals that connect to the processor. As a result, legacy input
signals such as A20M#, IGNNE#, INIT#, LINT0/INTR, LINT1/
NMI, PWRGOOD, SMI#, SLP#, and STPCLK# utilize GTL+ input
buffers. Legacy output signals (FERR# and IERR#) and nonAGTL+ signals (THERMTRIP# and PROCHOT#) also utilize GTL+
output buffers. All of these signals follow the same DC
requirements as AGTL+ signals, however the outputs are not
actively driven high (during a logical 0 to 1 transition) by the
processor (the major difference between GTL+ and AGTL+).
These signals do not have setup or hold time specifications in
relation to BCLK[1:0], and are therefore referred to as
“Asynchronous GTL+ Signals”. However , all of the Asynchrono us
GTL+ signals are required to be asserted for at least two BCLKs
in order for the processor to recognize them.
Bus AgentA component or group of components that, when combined,
represent a single load on the AGTL+ bus.
CrosstalkThe reception on a victim network of a signal imposed by
Flight TimeFlight time is a term in the timing equation that includes the
aggressor network(s) through inductive and capacitive coupling
between the networks.
• Backward Crosstalk - Coupling that creates a signal in a
victim network that travels in the opposite direction as the
aggressor’s signal.
• Forward Crosstalk - Coupling that creates a signal in a
victim network that travels in the same direction as the
aggressor’s signal.
• Even Mode Crosstalk - Coupling from a signal or multiple
aggressors when all the aggressors switch in the same
direction that the victim is switching.
• Odd Mode Crosstalk - Coupling from a signal or multiple
aggressors when all the aggressors switch in the opposite
direction that the victim is switching.

Intel® CoreTM 2 Duo processor with the Mobile Intel® 945GME Express Chipset
Intel® 945GME Express Chipset—About This Manual
needed to ensure the setup time of the receiver . More precisely,
flight time is defined as:
• The time difference between a signal at the input pin of a
receiving agent crossing the switching voltage (adjusted to
meet the receiver manufacturer’s conditions required for
AC timing specifications; i.e., ringback, etc.) and the output
pin of the driving agent crossing the switching voltage
when the driver is driving a test load used to specify the
driver’s AC timings.
• Maximum and Minimum Flight Time - Flight time variations
are caused by many different parameters. The more
obvious causes include variation of the board dielectric
constant, changes in load condition, crosstalk, power noise,
variation in termination resistance, and differences in I/O
buffer performance as a function of temperature, voltage,
and manufacturing process. Some less obvious causes
include effects of Simultaneous Switching Output (SSO)
and packaging effects.
• Maximum flight time is the largest acceptable flight time a
network will experience under all conditions.
• Minimum flight time is the smallest acceptable flight time a
network will experience under all conditions.
Infrared Data Assoc. The Infrared Data Association (IrDA) has outlined a specification
for serial communication between two devices via a bidirectional infrared data port. The 945GME platform has such a
port and it is located on the rear of the platform between the two
USB connectors.
IMVP6The Intel Mobile Voltage Positioning specification for the Intel
®
Core™ 2 Duo Processor. It is a DC-DC converter module that
supplies the required voltage and current to a single processor.
Inter-Symbol Interference
Inter-symbol interference is the effect of a previous signal (or
transition) on the interconnect delay. For example, when a
signal is transmitted down a line and the reflections due to the
transition have not completely dissipated, the following data
transition launched onto the bus is affected. ISI is dependent
upon frequency, time delay of the line, and the reflection
coefficient at the driver and receiver . ISI may impact both timing
and signal integrity.
Media Expansion Card
The Media Expansion Card (MEC) provides digital display options
through the SDVO interface. The MEC card also incorporates
video-in.
NetworkThe network is the trace of a Printed Circuit Board (PCB) that
completes an electrical connection between two or more
components.
OvershootThe maximum voltage observed for a signal at the device pad,
measured with respect to VCC.
PadThe electrical contact point of a semiconductor die to the
package substrate. A pad is only observable in simulations.
PinThe contact point of a component package to the traces on a
substrate, such as the motherboard. Signal quality and timings
may be measured at the pin.

and the arrival of a valid clock edge. This window may be
different for each type of bus agent in the system.
Simultaneous Switching Output (SSO) effects are differences in
electrical timing parameters and degradation in signal quality
caused by multiple signal outputs simultaneously switching
voltage levels in the opposite direction from a single signal or in
the same direction. These are called odd mode and even mode
switching, respectively . This simultaneous switching of multiple
outputs creates higher current swings that may cause additional
propagation delay (“push-out”) or a decrease in propagation
delay (“pull-in”). These SSO effects may impact the setup and/
or hold times and are not always taken into account by
simulations. System timing budgets should include margin for
SSO effects.

There are two main supported power supply configurations, Desktop and Mobile. The
Desktop solution consists of only using the ATX power supply. The Mobile solution
consists of only using the AC Brick.
Note:Desktop peripherals, including add-in cards, will not work in mobile power mode. If
desktop peripherals are used, the platform must be powered using desktop power
mode. The AC Brick power supply configuration does not provide the 12 V supply
required by most desktop peripherals.
Note:Select a power supply that complies with the "ATX12V" 1.1 specification. For more
information, refer to
http://www.formfactors.org.
Note:If the power button on the ATX power supply is used to shut down the system, wait at
least five seconds before turning the system on again to avoid damaging the system.
Other Devices and Adapters: The evaluation board functions much like a standard
desktop computer motherboard. Most PC-compatible peripherals can be attached and
configured to work with the evaluation board.
2.5Setting Up the Evaluation Board
Once the necessary hardware (described in Section 2.4) has been gathered, follow the
steps below to set up the Intel
Note:To locate items discussed in the procedure below, please refer to Section 4.0.
1. Create a safe work environment.
Ensure a static-free work environment before removing any components from their
anti-static packaging. The evaluation board is susceptible to electrostatic discharge
(ESD) damage, and such damage may cause product failure or unpredictable
operation. A flame retardant work surface must also be used.
Caution:Because of this susceptibility, it is recommended that an ESD wrist strap be
used when handling the board.
2. Inspect the contents of your kit.
Check for damage that may have occurred during shipment. Contact your sales
representative if any items are missing or damaged.
Caution:Since the board is not in a pro tective chassis, use caution when connecting
cables to this product.

945GME Express Chipset evaluation board.
Caution:Standby voltage is constantly applied to the board. Therefore, do not insert or
remove any hardware unless the system is unplugged.
Note:The evaluation board is a standard ATX form factor. An ATX chassis may be used if a
protected environment is desired. If a chassis is not used, standoffs must be used to
elevate the board off the working surface to protect the memory and to protect from
any accidental contact to metal objects.
3. Check the jumper default position setting. Refer to Figure 4 for jumper location.

3.4.2.11Clocks
The Intel® 945GME Express Chipset board uses a CK-410M and CK-SSCD compatible
solution. The CK-SSCD solution offers improved EMI performance by spreading the
radiated clock emissions over a wider spectrum than a single frequency. This is
accomplished while controlling the clock frequency deviation such that system
performance is not compromised. The FSB frequency is determined from decoding the
processor BSEL[2:0] pin settings.
3.4.2.12Real Time Clock
An on-board battery at BT5H1 maintains power to the real time clock (RTC) when in a
mechanical off state. A CR2032 battery is installed on the Intel

3.6.1Transition to S3
If enabled, the transition to S3 from the full-on state can be accomplished in the
following ways:
• The OS performs the transition through software.
• Press the front panel power button for less than four seconds (assuming the OS
power management support has been enabled).
Note:The power button is accessed by adding a switch to the pins 5 and 6 on the front panel
header J8J1.
3.6.2Transition to S4
“Wake on S4” (Suspend to disk) is controlled by the operating system.
3.6.3Transition to S5
The transition to S5 is accomplished by the following means:
• Press the front panel power button for less than four seconds (if enabled through
the OS).
• Press the front panel power button for more than four seconds to activate power
button override.
3.6.4Transition to Full-On
The transition to the Full-On state can be from S3 or S5. The transition from S3 is a low
latency transition that is triggered by one of the following wake events:
• Power management timer expiration
• Real Time Clock (RTC) triggered alarm
• Power button activation
• USB device interrupt
• ICH7M pin PME# assertion
•AC power loss
For AC power loss, the system operation is defined by register settings in the Intel
ICH7-M. Upon the return of power, a BIOS option, set prior to the power loss, allows
the system to either go immediately to the S5 state, or reboot to the Full-On state, no
matter what the state was before the power loss. External logic for this functionality is
not necessary. If the BIOS remains in the S5 state after AC power loss, only the power
button or the RTC alarm can bring the system ou t of the S5 state. The status of enabled
wake events will be lost.
3.7Power Measurement Support
Power measurement resistors are provided on the platform to measure the power of
most subsystems. All power measurement resistors have a tolerance of 1%. The value
of these power measurement resistors are 2 mΩ by default. Power on a particular
subsystem is calculated using the following formula:

Note:Do not move jumpers with the power on. Always turn off the power and unplug the
power cord from the computer before changing jumper settings. Failure to do so may
cause damage to the board.
Figure 4 shows the location of the configuration jumpers and switches.
Table 8 summarizes the jumpers and switches and gives their default and optional
settings.
The unsupported jumpers must remain in their default position or the operation of the
platform is unpredictable. The Intel
®
945GME Express Chipset board is shipped with
the jumpers and switches shunted in the default locations.

4.6.1H8 Programming Headers
The microcontroller for system management/keyboard/mouse control can be upgraded
in two ways. The user can either use a special MS-DOS* utility or use an external
computer connected to the system via the serial port on the board.
Caution:Make sure the motherboard is not powered on and the power supply is disconnected
before moving any of the jumpers.
T o progr am the microcontroller via the utility, the user must ensure that jumper J9H1 is
populated. Once the programming is complete, jumper J9H1 should be unpopulated.
If the user chooses to use an external computer connected to the system via the serial
port, there are five jumpers that have to be set correctly first. Please refer to Table 10
for a summary of these jumpers and see Figure 4 for the location of each jumper.
Here is the sequence of events necessary to program the H8.
1. With the board powered off, move the five jumpers listed in Table 10 to the
programming stuffing option.
2. Power the S5 voltage rails by attaching an AC brick or an ATX power supply to the
system.

3. Program the H8 via the serial port.
4. Disconnect the power supply from the system.
5. With the board powered off, move the five jumpers listed in Table 10 back to the
default stuffing option.

into the socket, turn the screw 180 degrees clock-wise to secure the CPU in the socket.
Note that the slot on the screw aligns with the lock and unlock legend on the case of
the CPU socket.
Caution:Please refer to the CPU installation instruction in Appendix A prior to inserting the CPU
as the CPU and socket can be easily damaged.
4.6.2.2PCI Express* (x16)
The platform has one x16 lane PCI Express* Graphics slot and supports either x1 or
x16 modes. The slot is wired “lane reversed” which connects the Intel
Express Chipset lanes 0 through 15 to lanes 15 through 0 on the slot. The Intel
945GME Express Chipset will internally un-reverse this wiring since its CFG9 power-on
strap is tied low.
Table 12.PCI Express* (x16) Pinout (J6C1) (Sheet 1 of 3)
When not being used for PCI Express*, the x16 slots can be used for Serial Digital
Video Out (SDVO). SDVO cards provide for a third party vendor secondary graphics
add-on such as a digital panel interface.
The SDVO interface will also support a Media Expansion Card (MEC), which provide TV
Capture over the PCI Express* x1 port in addition to the standard SDVO card video out
capabilities.

Appendix A Heat Sink Installation Instructions
It is necessary for the Intel® CoreTM 2 Duo processor to have a thermal solution
attached to it in order to keep it within its operating temperature.
A heat sink is included in the kit. To install the heat sink:
1. Remove the heatsink from its package and separate the fan heatsink portion from
the heatsink backplate.
Figure 6.Heatsink and Backplate
2. Examine the base of the heatsink, where contact with the processor die is made.
This surface should be clean of all materials and greases. Wipe the bottom surface
clean with isopropyl alcohol.
3. Place the backplate on the underside of the board so that the pins protrude through
the holes in the system board around the processor.

4. Clean the die of the processor with isopropyl alcohol before the heatsink is attached
to the processor. This ensures that the surface of the die is clean.
5. Remove the tube of thermal grease from the package and use it to coat the bottom
of the heatsink thermal plate with the thermal grease.

7. While keeping the activation arm compressed, place the heatsink over the pins of
the heatsink backplate. Lower the heatsink until the lugs have inserted into the
base of the heatsink. Slide the heatsink ov er the lugs on the backplate pins so that
the base is directly over the processor die and the pins on the backplate have
traveled the entire length of the channel in the heatsink base. Slowly let go of the
activation arm until the base of the heatsink makes contact with the processor die.
The heatsink base should be flat on top of the processor die.
