IMPORTANT NOTE: When the system boots without the CRT being
connected, there will be no image on screen when you insert the
CRT/VGA cable. To show the image on screen, the hotkey must be
pressed (CTRL-ALT-F1).
Remarks: The IDE connector on board does not support OS
installation in hard drive. A system hard drive connected to this IDE
cannot be booted up to OS.

INTRODUCTION
Introduction
Product Description
The MI945 Mini ITX board incorporates the Mobile Intel® GM45 Express
Chipset for Embedded Computing, consisting of the Intel® GM45 Graphic
Memory Controller Hub (GMCH) and Intel® I/O Controller Hub (ICH9-M), an
optimized integrated graphics solution with a 1066MHz and 800MHz front-side
bus. Dimensions of the board are 170mm x 170mm.
The integrated powerful 3D graphics engine, based on Intel® Graphics Media
Accelerator X3500 (Intel® GMA X3500) architecture, operates at core speeds of
up to 533 MHz. It features a low-power design, is validated with the Intel® Core
2 Duo processors on 45nm process. With dual channel DDR2 800MHz two
SoDIMM sockets on board, the board supports up to 4GB of DDR2 system
memory.
Intel® Graphics supports a unique intelligent memory management scheme
called Dynamic Video Memory Technology (DVMT). DVMT handles diverse
applications by providing the maximum (384MB) availability of system memory
for general computer usage, while supplying additional graphics memory when a
3D-intensive application requests it. The Intel GMA X3500 graphics
architecture also takes advantage of the high-performance Intel processor. Intel
GMA X3500 graphics supports Dual Independent Display technology.
The main features of the board are:
Supports Intel® CoreTM 2 Duo (Penryn 1066MHz)
Supports up to 2.53GHz, 1066MHz/800MHz FSB
Two DDR2 SoDIMM, Max. 4GB memory
Onboard Gigabit PHY and Intel PCI-Express Gigabit LAN
Intel® GM45 Express VGA for CRT / LVDS
4x SATA, 8x USB 2.0, 4x COM, Watchdog timer
1x Mini PCI-E (Mini Card), 1x PCI, 1xPCI-E(x1) slots
Optional daughter cards:
ID390: Chrontel 7308, supports 24 bit single or dual LVDS channel
ID390C: Chrontel 7021, supports CRT
ID391: Chrontel 7307C, single DVI (connector on cable)
ID391D: Chrontel 7307C, dual DVI (connector on cable)
ID392D: Chrontel 7307C, dual DVI (one connector on card and one on cable)

INSTALLATIONS
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.
Installing the CPU
The MI910 board supports a Socket 478MN (Merom) processor socket
for Intel® CoreTM 2 Duo, Intel® Celeron mobile 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.

Installing the Memory
The MI945 board supports two DDR2 memory socket for a maximum
total memory of 4GB 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 aligned
with that 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.
