Introduction
Product Description
The 2808030 Mini ITX board incorporates the Mobile Intel® 910GML/915GME
Express Chipset for Embedded Computing, consisting of the Intel® 910GML/
915GMEGraphic Memory Controller Hub (GMCH) and Intel® I/O Controller
Hub 6-M (ICH6-M), is an optimized integrated graphics solution with a
400/533MHz front-side bus.
The integrated 32-bit 3D graphics engine, based on Intel® Graphics Media
Accelerator 900 (Intel® GMA 900) architecture, operates at core speeds of up to
320 MHz. It features a low-power design, is validated with Intel® Pentium M/
Celeron® M processors on 130nm or 90nm process. With one DIMM socket on
board, the board supports up to 1GB of DDR2 system memory (400MHz for
910GML, 400/533MHz for 915GME chipset).
Intel® Graphics supports a unique intelligent memory management scheme
called Dynamic Video Memory Technology (DVMT). DVMT handles diverse
applications by providing the maximum availability of system memory for
general computer usage, while supplying additional graphics memory when a
3D-intensive application requests it. The Intel GMA 900 graphics architecture
also takes advantage of the high-performance Intel processor. Intel GMA 900
graphics supports Dual Independent Display technology.
The main features of the board are:
Supports Celeron® M processors, 400MHz FSB (910GML chipset)
Supports Socket 479, 533/400MHz FSB (915GMEchipset)
One DDRII SDRAM DIMM supports up to 1GB of DDR2 400MHz
(910GML chipset), DDR2 400/533MHz (915GMEchipset)
Onboard 10/100 BaseT and Marvell PCI-Express Gigabit LAN
Intel® 915 Express VGA for CRT, SDVO port supports LVDS and
DVI / LVDS
2x SATA, 6x USB 2.0, 4x COM, Watchdog timer
1x PCI, 1x MiniPCIe, CF socket, DC-in for +12V input
Dimensions of the board are 170mm x 170mm.

INSTALLATIONS
Installing the CPU
The 2808030 board supports a Socket 479 processor socket for Intel®
Pentium®M or Celeron®M processors.
The processor socket comes with a screw to secure the processor. As
shown in the left picture below, loosen the screw first before inserting
the processor. Place the processor into the socket by making sure the
notch on the corner of the CPU corresponds with the notch on the inside
of the socket. Once the processor has slide into the socket, fasten the
screw. Refer to the figures below.
NOTE: Ensure that the CPU heat sink and the CPU top surface are in
total contact to avoid CPU overheating problem that would
cause your system to hang or be unstable.

INSTALLATIONS
Installing the Memory
The 2808030 board supports one DDR2 memory socket for a maximum
total memory of 1GB in DDR2 memory type.
Installing and Removing Memory Modules
To install the DDR2 modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR2 module so that the key of the DDR2 module align
with those on the memory slot.
2. Gently push the DDR2 module in an upright position until the clips of
the slot close to hold the DDR2 module in place when the DDR2
module touches the bottom of the slot.
3. To remove the DDR2 module, press the clips with both hands.
