Processors. The chipset is equipped with Intel
®
Q45 + ICH10DO.
Moreover, the system memory features two 240-pin DDRIII
800/1066 SDRAM up to 4GB. It deploys two PCI-Express LAN
ports that consist of 10/100/1000Base-TX Ethernet RJ-45 ports.
AIS-Q454 condensed appearance features desktop and wallmount
form factor that fits nicely into a space-limited environment.
This AIS-Q454 equipped with two 3.5” Hard Disk Drive with SATA
II interface and one optional CompactFlash
TM
Type II socket.
Moreover, the flexible expansion interfaces feature one
PCI-Express﹝x16﹞, one PCI-Express﹝x4﹞, and two PCI slots.
In addition, this model supports two COM ports and six USB2.0
(four ports at I/O interfaces and two ports on the front panel).
Furthermore, the Realtek ALC888 supports HD audio codec and
the AIS-Q454 can support dual displays with VGA and DVI via
®
Intel
Q45.
With the increasing demands of high performance in audio and
video, AAEON released the specific Advanced System Controller

2.5 Setting Jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal clip (often protected by
a plastic cover) that slides over the pins to connect them. To “close”
a jumper you connect the pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will
have three pins, labeled 1, 2 and 3. In this case you would connect
either pins 1 and 2 or 2 and 3.

Open Closed Closed 2-3
A pair of needle-nose pliers may be helpful when working with
jumpers.
If you have any doubts about the best hardware configuration for
your application, contact your local distributor or sales
representative before you make any change.
Generally, you simply need a standard cable to make most
connections.

3.1 System Test and Initialization
These routines test and initialize board hardware. If the routines
encounter an error during the tests, you will either hear a few short
beeps or see an error message on the screen. There are two kinds
of errors: fatal and non-fatal. The system can usually continue the
boot up sequence with non-fatal errors. Non-fatal error messages
usually appear on the screen along with the following instructions:
Press <F1> to RESUME
Write down the message and press the F1 key to continue the boot
up sequence.
System configuration verification
These routines check the current system configuration against the
values stored in the CMOS memory. If they do not match, the
program outputs an error message. You will then need to run the
BIOS setup program to set the configuration information in memory.
There are three situations in which you will need to change the
CMOS settings:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration
information has been erased.
The AIS-Q454 CMOS memory has an integral lithium battery
backup for data retention. However, you will need to replace the
complete unit when it finally runs down.

( K version )
Below are the procedures to complete its configuration and the
AAEON intial watchdog timer program is also attached based on
which you can develop customized program to fit your application.
Configuring Sequence Description
After the hardware reset or power-on reset, the ITE 8718 enters the
normal mode with all logical devices disabled except KBC.
There are three steps to complete the configuration setup: (1) Enter
the MB PnP Mode; (2) Modify the data of configuration registers; (3)
Exit the MB PnP Mode. Undesired result may occur if the MB PnP
Mode is not exited normally.

AIS-Q454
(1) Enter the MB PnP Mode
To enter the MB PnP Mode, four special I/O write operations are to
be performed during Wait for Key state. To ensure the initial state of
the key-check logic, it is necessary to perform four write opera -tions
to the Special Address port (2EH). Two different enter keys are

(2) Modify the Data of the Registers
All configuration registers can be accessed after entering the MB
PnP Mode. Before accessing a selected register, the content of
Index 07h must be changed to the LDN to which the register
belongs, except some Global registers.
(3) Exit the MB PnP Mode
Set bit 1 of the configure control register (Index=02h) to 1 to exit the
MB PnP Mode.

This register is write only. Its values are not sticky; that is to say, a
hardware reset will automatically clear the bits, and does not
require the software to clear them.
