Introduction

Product Description

The MI945X 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 DDR3 800/1066MHz
two SODIMM sockets on board, the board supports up to 4GB of 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® Mobile Core 2 Duo/Core 2 Quad Processor (Penryn)
 Supports up to 2.93GHz, 1066MHz/800MHz FSB
 Two DDR3 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-E (x16) slots

INSTALLATIONS

Installing the CPU

The MI945X board supports a Socket M socket for Intel® Core

TM

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.

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 MI945X board supports two DDR3 memory socket for a maxim um
total memory of 4GB in DDR3 memory type.

Installing and Removing Memory Modules

To install the DDR3 modules, locate the memory slot on the board and
perform the following steps:

1. Hold the DDR3 module so that the key of the DDR3 module aligned

with that on the memory slot.

2. Gently push the DDR3 module in an upright position until the clips of

the slot close to hold the DDR3 module in place when the DDR3
module touches the bottom of the slot.

3. To remove the DDR3 module, press the clips with both hands.

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 devi ce 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 p ressing 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.

The section below the setup items of the Main Menu displays the control

control keys section, there is another section, which displays information
on the currently highlighted item in the list.

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.

BIOS SETUP

MI945X User’s Manual 27

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.

IDE HDD Block Mode

This field allows your hard disk controller to use the fast block mode to
transfer data to and from your hard disk drive.

IDE DMA transfer access

This field, by default, is enabled

On-chip Primary/Secondary PCI IDE

The integrated peripheral controller contains an IDE interface with
support for two IDE channels. Select Enabled to activate each channel
separately.

IDE Primary/Secondary Master/Slave PIO

These fields allow your system hard disk controller to work faster.
Rather than have the BIOS issue a series of commands that transfer to or
from the disk drive, PIO (Programm ed Input/Output) allows the B IOS to
communicate with the controller and CPU directly.

The system supports five modes, numbered from 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select
the best available mode.

IDE Primary/Secondary Master/Slave UDMA

These fields allow your system to improve disk I/O throughput to

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.
