INTRODUCTION
Introduction
Product Description
The MI920 Mini ITX board incorporates the Mobile Intel® 910GML/915GM
Express Chipset for Embedded Computing, consisting of the Intel® 910GML/
915GM Graphic 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 915GM 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 (915GM chipset)
One DDRII SDRAM DIMM supports up to 1GB of DDR2 400MHz
(910GML chipset), DDR2 400/533MHz (915GM chipset)
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.
Ordering Information:
MI920F: Socket 479, 915GM, ICH6M, supports DVI, LVDS, 1x 10/100 LAN,
1x Gigabit LAN, Mini PCI-E
MI920L-C6K: Celeron M 600M/512K , 910GML, ICH6M, supports DVI,

INSTALLATIONS
Installing the CPU
The MI920 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 MI920 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 m odule 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.

The section below the setup items of the Main Menu displays the control
keys for this menu. At the bottom of the Main Menu just below the
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.
MI920 User’s Manual 23
BIOS SETUP
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

Virus Warning
If this option is enabled, an alarm message will be displayed when trying to write
on the boot sector or on the partition table on the disk, which is typical of the
virus.
CPU L1 and L2 Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). CPUs from 486-type on up contain internal cache
memory, and most, but not all, modern PCs have additional (external) cache
memory. When the CPU requests data, the system transfers the requested data
from the main DRAM into cache memory, for even faster access by the CPU.
These items allow you to enable (speed up memory access) or disable the cache
function. By default, these items are Enabled.

When the typematic rate is enabled, this item allows you to set the time
interval for displaying the first and second characters. By default, this
item is set to 250msec.
Security Option
This field allows you to limit access to the System and Setup. The default

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.
