Introduction
Product Description
The MI810 Mini ITX board incorporates the Intel® 945GSE Express Chipset
with ICH7M, configured with the Intel Atom processor N270 at 1.6GHz,
FSB533 and the Mobile Intel 945GSE Express Chipset with the ICH7M.
The MI810 Mini ITX board features the Intel's Graphics Media Accelerator 950
core, making it compatible with Windows Vista Premium, and Chrontel CH7307
DVI accelerator to support display interfaces including VGA CRT, dual channel

total memory of 2GB 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.

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.

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
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.

With the field, there is the option to choose, aside from the hard disks connected,
“Bootable add-in Cards” which refers to other external devices.
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 / L2 / L3 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.

Hyper-Threading Technology
By default, this function is enabled.
Quick Power On Self Test
When enabled, this field speeds up the Power On Self Test (POST) after
the system is turned on. If it is set to Enabled, BIOS will skip some
items.
First/Second/Third Boot Device
These fields determine the drive that the system searches first for an
operating system. The options available include Floppy, LS120, Hard
Disk, CDROM, ZIP100, USB-Floppy, USB-ZIP, USB-CDROM, LAN
and Disable.
Boot Other Device
These fields allow the system to search for an OS from other devices
other than the ones selected in the First/Second/Third Boot Device.
Swap Floppy Drive
This item allows you to determine whether or not to enable Swap Floppy
Drive. When enabled, the BIOS swaps floppy drive assignments so that
Drive A becomes Drive B, and Drive B becomes Drive A. By default,
this field is set to Disabled.
Boot Up Floppy Seek
This feature controls whether the BIOS checks for a floppy drive while
booting up. If it cannot detect one (either due to improper configuration
or its absence), it will flash an error message.
Boot Up NumLock Status
This allows you to activate the NumLock function after you power up
the system.
Gate A20 Option
This field allows you to select how Gate A20 is worked. Gate A20 is a
device used to address memory above 1 MB.
Typematic Rate Setting
When disabled, continually holding down a key on your keyboard will
generate only one instance. When enabled, you can set the two typematic
controls listed next. By default, this field is set to Disabled.
Typematic Rate (Chars/Sec)
When the typematic rate is enabled, the system registers repeated
keystrokes speeds. Settings are from 6 to 30 characters per second.

BIOS SETUP
Typematic Delay (Msec)
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
value is Setup. When you select System, the system prompts for the User
Password every time you boot up. When you select Setup, the system
always boots up and prompts for the Supervisor Password only when the
Setup utility is called up.
APIC Mode
APIC stands for Advanced Programmable Interrupt Controller. The
default setting is Enabled.
MPS Version Control for OS
This option is specifies the MPS (Multiprocessor Specification) version
for your operating system. MPS version 1.4 added extended
configuration tables to improve support for multiple PCI bus
configurations and improve future expandability. The default setting is
1.4.
OS Select for DRAM > 64MB
This option allows the system to access greater than 64MB of DRAM
memory when used with OS/2 that depends on certain BIOS calls to
access memory. The default setting is Non-OS/2.
Report No FDD For WIN 95
If you are using Windows 95/98 without a floppy disk drive, select
Enabled to release IRQ6. This is required to pass Windows 95/98's SCT
test. You should also disable the Onboard FDC Controller in the
Integrated Peripherals screen when there's no floppy drive in the system.
If you set this feature to Disabled, the BIOS will not report the missing
floppy drive to Win95/98.
Small Logo (EPA) Show
The EPA logo appears at the right side of the monitor screen when the
system is boot up. The default setting is Disabled.

change specifications of the installed DRAM or the installed CPU.
DRAM RAS# to CAS# Delay
This option allows you to insert a delay between the RAS (Row Address
Strobe) and CAS (Column Address Strobe) signals. This delay occurs
when the SDRAM is written to, read from or refreshed. Reducing the
