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 2807660 series all-in-one mini ITX is designed to fit a high
performance Pentium® M based processor and compatible for
high-end computer system application with PCI bus architecture. It is
made to meet today’s demanding pace, and keep complete
compatibility with hardware and software designed for the IBM PC/AT.
The onboard devices support one PCI slot, integrated graphics, and
onboard three Marvell Gigabit Ethernet controllers. It’s beneficial to
build up a high performance and high data availability system for VARs,
or system integrators.
2807660 series support the following processors: Intel® uFC-PGA 478
Pentium® M/Celeron® M processor FSB 400/533MHz with 0.90 and
0.13 micron technology.
This mini ITX can run with Intel® socket 479 Pentium®/Celeron® M
processors and support DIMM up to 2GB dual-channel DDR2 533
memory. The enhanced onboard one PCI-IDE interface can support 1
drive up to PIO mode 4 timing and Ultra ATA 33/66/100 synchronous
mode feature, one CF socket interface, and 2 serial ATA high-speed
data transfers at up to 150MB/s connectors. The onboard super I/O
chipset supports two serial ports, one SIR(Serial Infrared) port, two
high performance 16C550-compatible UARTs provide 16-byte
send/receive FIFOs, and two RS-232 serial port interfaces. Besides,
H/W monitor function, Intel® High Definition Audio as 5.1 surround
sound, six Hi-Speed USB2.0 ports offering up to 40X greater
bandwidth over USB1.1. Also provide dual display function by VGA and
DVI, by VGA, and LVDS interface.

2
The mini ITX standard makes the 2807660 series work with the one
slot PCI and one 6-pin Mini DIN connector for PS/2 mouse and
keyboard. The onboard Flash ROM is used to make the BIOS update
easier. The high precision Real Time Clock/calendar is built to support
Y2K for accurate scheduling and storing configuration information. One
20-pin standard connector is designed to support ATX power function.
A feature of CPU overheat protection will give user more security and
stability. All of these features make 2807660 series excellent in
stand-alone applications.
NOTE:
 The 2807660 series only support Intel® Pentium®/Celeron® M
processor (Dothan 400/533 FSB) for 0.13 and 0.90 micron.

determines whether the DVI is connected to a DVI
monitor. When terminated, the monitor is required
to apply a voltage greater than 2.4 volts. Changes
on the status of this pin will be relayed to the
graphics controller via the P-OUT/TLDET* or
GPIO(1)/TLDET* pin pulling low.
TMDSDATA I/O DVI I2C Data: This signal is used as the I2C DOC
clock for a digital display connector (i.e. TV-Out
Encoder, TMDS transmitter). This signal is
tri-stated during a hard reset.
TMDSDCLK I/O DVI DOC Clock: This signal is used as the DOC
clock for a digital display connector (i.e. primary
