Safety Instructions
Integrated circuits on computer boards are sensitive to static electricity. To
avoid damaging chips from electrostatic discharge, observe the following
precautions:
 Do not remove boards or integrated circuits from their anti-static packaging
until you are ready to install them.
 Before handling a board or integrated circuit, touch an unpainted portion of
the system unit chassis for a few seconds. This helps to discharge any static
electricity on your body.
 Wear a wrist-grounding strap, available from most electronic component
stores, when handling boards and components. Fasten the ALLIGATOR clip
of the strap to the end of the shielded wire lead from a grounded object.
Please wear and connect the strap before handle the product to ensure
harmlessly discharge any static electricity through the strap.
 Please use an anti-static pad when putting down any components or parts or
tools outside the computer. You may also use an anti-static bag instead of
the pad. Please inquire from your local supplier for additional assistance in
finding the necessary anti-static gadgets.
NOTE: DO NOT TOUCH THE BOARD OR ANY OTHER SENSITIVE
COMPONENTS WITHOUT ALL NECESSARY ANTI-STATIC
PROTECTIONS.

General Description
The 2807960 is an Intel® 945GM GMCH chipset-based board
designed. The 2807960 is an ideal all-in-one mITX board. Additional
features include an enhanced I/O with CF, DVI/CRT/LVDS, TV-Out,
dual Giga LAN, audio, SPDIF, SATA, 6 COM, IrDA, and USB2.0
interfaces.
Designed with the Intel® 945GM GMCH, the board supports Intel®
Core™ 2 Duo/Core™ Duo/Core™ Solo processor 1.66~2.33GHz.
Its onboard ATA/33/66/100 to IDE drive interface architecture allows
the 2807960 to support data transfers of 33, 66 or 100MB/sec. to one
IDE drive connection. The Intel® ICH7-M serial ATA controller with two
ports supporting transfer rates up to 150MB/sec.
Onboard Intel® 945GM GMCH for CRT display with DVMT or
CHRONTEL 7307 for DVI display supporting up to 2048 x 1536. It also
supports 18-bit single channel/36-bit dual channel LVDS interface.
System memory is also sufficient with the one SO-DDRII socket that
can support up to 1GB.
Additional onboard connectors include an advanced USB2.0 port
providing faster data transmission. And two external RJ-45 connectors
for 10/100 Based Ethernet use.

To ensure the reliability in an unmanned or standalone system, the
watchdog timer (WDT) onboard 2807960 is designed with software
that does not need the arithmetical functions of a real-time clock chip. If
any program causes unexpected halts to the system, the onboard WDT
will automatically reset the CPU or generate an interrupt to resolve
such condition.
