Application Notes
1. DisplayPort support
When PCI-E [x16] signals are occupied by the graphics card, SDVO,
DisplayPort, HDMI, DVI signals cannot be used or implemented.
Otherwise, when either of SDVO, DisplayPort, HDMI or DVI is used or
implemented, the others cannot be used or implemented simultaneously.
2. Linux support
Some functions of COM-45GS cannot work well in some Linux versions, for
example, LAN function in Fedora 9 because of the supporting issue of new
chipset. AAEON had tested Fedora 10 on COM-45GS and the functions
work well.
3. IDE device support
COM-45GS supports one IDE device. When using it, please follow the
instructions below:
(1) Please enter the BIOS to change the default setting from "Disabled" to
"Enabled".
==> Path: Integrated Peripherals --> OnChip IDE Device --> IDE HDD
Support
(2) Set it as "Master" device.
(3) Please enter the BIOS to change the setting from "Enabled" to "Disabled"
when disconnecting IDE device.
==> If you do not do it, the system will boot up slowly.
4. OS installation issue
When you use RAID function and install the OS, please use the USB optical
drive to install OS only.
If you use the SATA optical drive, it will not be recognized at all.
5. PXE issue
When you use the PXE function, please enter the BIOS to change the default
setting from "Disabled" to "Enabled".
==> Path: Integrated Peripherals --> OnChip IDE Device --> LEGACY Mode
Support
For more detailed information, please contact with AAEON Customer
Service Department for further assistance.

1.1 Introduction
To accommodate fast growing marketing segments, AAEON
has developed a brand new COM Express CPU Module,
COM-45GS. The COM-45GS adopts Intel®CoreTM 2 Duo/
Celeron M (SFF, 22 x 22mm) processor and Intel®GS45+ICH9M
SFF chipset, offering high speed one PCI-Express［x16］that
can be configured as PCI-Express［x1］/［x2］/［x4］/［x8］,
five PCI-Express［x1］, 32-bit PCI x 4, LPC bus x 1, SMBus x 1,
and I2C x 1 interfaces for your high performance applications
requiring high-speed and greater stability. The COM Express
CPU Module offers flexibility and time-to-market advantages
over a fully customized platform.
AAEON’s COM-45GS supports 24-bit dual-channel LVDS LCD
interface and supports two DDRIII 800/1066 SODIMM memory
module up to 8GB. A high definition audio interface is available
to connect to an audio codec on the carrier board. Moreover,
three SATA II interfaces are featured giving the user flexibility in
storage choices.
To satisfy the requirements of applications in gaming,
entertainment, industrial automation, medical, POS, and etc,
COM Express carrier boards can be designed targeting the
needs of the different market segments.

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
