Application Notes
1. After installing drivers in AT power mode under Windows®XP
operation, there is no message: “It is now safe to turn off your
computer” during the procedure of turn-off.
2. Hyper threading technology only supports ATX mode rather than
AT mode.
3. If you are going to use the add-on PCI Video Card instead of the
onboard Intel®945GSE VGA function, you have to uninstall the
onboard Intel®VGA driver before installing the driver of add-on
PCI Video Card.
4. While installing OS into SATA HDD, please do not attach any
IDE HDD during installation. If you need one IDE HDD as
storage device, please attach IDE HDD after finishing the
installation.
5. If using LCD by 800x480 pixel,
A. Please set LCD as primary
B. Operation procedure to run dual display or extended display
under Window®XP:
a. Please use control panel -> display device-> adjust
b. Use right button of mouse to select
6. Under DOS mode, if setting simultaneous displays
A. 24-bit LVDS LCD (from Chrontel 7308) + VGA: the screen
shrinks at any resolution.
B. 18-bit LVDS LCD + VGA: the screen shrinks at resolution
640x480.
7. DIO address is “200H.”
8. Module can run without RTC battery.
9. Two options to select AT/ATX power mode
 Auto switch circuit
 SMT jumper
10. SDVOCTL_CLK & SDVOCTL_DATA are connected to 945GSE;
SMBUS is connected to ICH7M; I2C bus is connected to
Winbond SIO.

ETX CPU Module ETX-945GSE
Chapter 1 General Information 1 - 2
1.1 Introduction
ETX-945GSE is able to equip with Intel®AtomTM N270 processor
and has one 200-pin DDR II 400/533 SODIMM to support system
memory up to 1GB. ETX-945GSE adopts Intel®945GSE+ ICH7M
chipset that implements serial technologies with high performance.
In addition, ETX-945GSE accommodates user-friendly expansion
interfaces, ex: four 32-bit PCI, one ISAbus, one SMBus and one
I2C interface.
For the display specifications, ETX-945GSE integrates Intel®
945GSE and shared system memory is up to 224MB/DVMT 3.0.
The display of ETX-945GSE supports CRT and 18/24-bit
dual-channel LVDS LCD. Moreover, it supports NTSC/ PAL and
Composite Video, S-Video on the carrier board. In addition, one
SDVO port can be used through the SDVO connector to provide
more flexibility for display function.
If you are looking for an economic, time-saving and high
performance solution, ETX-945GSE definitely is your first choice.

2.1 Safety Precautions
Always completely disconnect the power cord
from your board whenever you are working on
it. Do not make connections while the power is
on, because a sudden rush of power can
damage sensitive electronic components.
Always ground yourself to remove any static
charge before touching the board. Modern
electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in the chassis
