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.

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.

BIOS SETUP
BIOS Introduction
The Award BIOS (Basic Input/Output System) installed in your
computer system’s ROM supports Intel processors. The BIOS provides
critical low-level support for a standard device such as disk drives, serial
ports and parallel ports. It also adds virus and password protection as
well as special support for detailed fine-tuning of the chipset controlling
the entire system.
BIOS Setup
The Award BIOS provides a Setup utility program for specifying the
system configurations and settings. The BIOS ROM of the system stores
the Setup utility. When you turn on the computer, the Award BIOS is
immediately activated. Pressing the <Del> key immediately allows you
to enter the Setup utility. If you are a little bit late pressing the <Del> key,
POST (Power On Self Test) will continue with its test routines, thus
preventing you from invoking the Setup. If you still wish to enter Setup,
restart the system by pressing the ”Reset” button or simultaneously
pressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart by
turning the system Off and back On again. The following message will
appear on the screen:
Press <DEL> to Enter Setup
In general, you press the arrow keys to highlight items, <Enter> to select,
the <PgUp> and <PgDn> keys to change entries, <F1> for help and
<Esc> to quit.
When you enter the Setup utility, the Main Menu screen will appear on
the screen. The Main Menu allows you to select from various setup
functions and exit choices.

Note:
If the system cannot boot after making and saving system
changes with Setup, the Award BIOS supports an override to
the CMOS settings that resets your system to its default.
Warning:
It is strongly recommended that you avoid making any
changes to the chipset defaults. These defaults have been
carefully chosen by both Award and your system
manufacturer to provide the absolute maximum performance
and reliability. Changing the defaults could cause the system
to become unstable and crash in some cases.

Standard CMOS Setup
“Standard CMOS Setup” choice allows you to record some basic
hardware configurations in your computer system and set the system
clock and error handling. If the motherboard is already installed in a
working system, you will not need to select this option. You will need to
run the Standard CMOS option, however, if you change your system
hardware configurations, the onboard battery fails, or the configuration
stored in the CMOS memory was lost or damaged.

The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that can

of the operating system, it signals this by causing an IRQ to occur. When

Password sets a password that will be used exclusively on the system. To
specify a password, highlight the type you want and press <Enter>. The
Enter Password: message prompts on the screen. Type the password, up
to eight characters in length, and press <Enter>. The system confirms
your password by asking you to type it again. After setting a password,
the screen automatically returns to the main screen.
To disable a password, just press the <Enter> key when you are prompted
to enter the password. A message will confirm the password to be
disabled. Once the password is disabled, the system will boot and you can
enter Setup freely.
Save & Exit Setup
This option allows you to determine whether or not to accept the
modifications. If you type “Y”, you will quit the setup utility and save all
changes into the CMOS memory. If you type “N”, you will return to
Setup utility.
Exit Without Saving
Select this option to exit the Setup utility without saving the changes you
have made in this session. Typing “Y” will quit the Setup utility without
saving the modifications. Typing “N” will return you to Setup utility.

C. Watchdog Timer Configuration
The WDT is used to generate a variety of output signals after a user
programmable count. The WDT is suitable for use in the prevention of
system lock-up, such as when software becomes trapped in a deadlock.
Under these sorts of circumstances, the timer will count to zero and the
selected outputs will be driven. Under normal circumstance, the user will
restart the WDT at regular intervals before the timer counts to zero.
