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.

This chapter describes the different settings available in the Award  
BIOS that comes with the board. The topics covered in this chapter are  
as follows:  
MI920 User’s Manual

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.

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  
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.

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.  
MI920 User’s Manual

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.  
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

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.
