not installed and used in accordance with the instruction manual, may  
cause harmful interference to radio communications. Operation of this  
device in a residential area is likely to cause harmful interference in  
which case the user will be required to correct the interference at his/her  
own expense. The user is advised that any equipment changes or modifi-  
cations not expressly approved by the party responsible for compliance  
would void the compliance to FCC regulations and therefore, the user's  
authority to operate the equipment.  
Caution! There is a danger of a new battery exploding if  
it is incorrectly installed. Do not attempt to  
recharge, force open, or heat the battery.  
Replace the battery only with the same or

Product warranty  
Advantech warrants to you, the original purchaser, that each of its prod-  
ucts will be free from defects in materials and workmanship for two years  
from the date of purchase.  
This warranty does not apply to any products which have been repaired or  
altered by persons other than repair personnel authorized by Advantech,  
or which have been subject to misuse, abuse, accident or improper instal-  
lation. Advantech assumes no liability under the terms of this warranty as  
a consequence of such events.  
If an Advantech product is defective, it will be repaired or replaced at no  
charge during the warranty period. For out-of-warranty repairs, you will  
be billed according to the cost of replacement materials, service time and  
freight. Please consult your dealer for more details.  
If you think you have a defective product, follow these steps:  
1.  
Collect all the information about the problem encountered. (For  
example, type of PC, CPU speed, Advantech products used, other  
hardware and software used, etc.) Note anything abnormal and list  
any on-screen messages you get when the problem occurs.  
2.  
3.  
Call your dealer and describe the problem. Please have your man-  
ual, product, and any helpful information readily available.  
If your product is diagnosed as defective, obtain an RMA (return  
material authorization) number from your dealer. This allows us to  
process your return more quickly.  
4.  
5.  
Carefully pack the defective product, a fully-completed Repair and  
Replacement Order Card and a photocopy proof of purchase date  
(such as your sales receipt) in a shippable container. A product  
returned without proof of the purchase date is not eligible for war-  
ranty service.  
Write the RMA number visibly on the outside of the package and  
ship it prepaid to your dealer.

800 MHz front-side bus, supporting Intel Pentium 4 / Celeron D CPUs up  
to 3.8/3.06 GHz and uses up to 4 GB of dual-channel 400/533 MHz  
DDRII SDRAM. The integrated VGA controller dynamically shares sys-  
tem memory up to 128 MB, providing a low-cost but high-performance  
graphic function. With a south-bridge north-bridge channel Direct Media  
Interface (DMI) which provides a data rate up to 2 GB/s, AIMB-760  
eliminates the bottleneck between the chipsets and can be equipped with  
high-performance network connection ports and I/O functions. The dual/  
single Gigabit LAN port(s) and PCI-Express x1 bus which have a data  
throughput of up to 500 MB/s make AIMB-760 suitable for intense  
industrial network applications. There are 2 PCI-Express x1 slots (one for  
the riser card) and 5 32-bit/33MHz PCI slots on the AIMB-760, providing  
good expansion capability. The 4 on-board SATA connectors not only  
provide a faster data transmission rate of up to 150 MB/s but also higher  
read/write efficiency by supporting Advanced Host Controller Interface  
(AHCI) technology. The thin, long SATA cable also ease cabling and  
thermal design inside the chassis. The 8 USB ports (4 rear I/O ports, 4 on-  
board headers) provide flexibility and convenience when using USB  
devices.  
A backup of CMOS data is stored in the Flash memory, which protects  
BIOS setup data even after a battery failure. Also included is a 255-level  
watchdog timer, which resets the CPU or generates an interrupt if a pro-  
gram cannot be executed normally. This enables reliable operation in  
unattended environments.  
The remote management interface enables the AIMB-760 to be managed  
through Ethernet when it is connected to the SNMP-1000 Remote HTTP/  
SNMP System Manager.

operation. The remote management interface allows the system to be  
managed through Ethernet when it is connected to the SNMP-1000  
Remote HTTP/SNMP System Manager.  
• BIOS CMOS backup and restore: When BIOS CMOS setup has been  
completed, data in the CMOS RAM is automatically backed up to the  
Flash ROM. This is particularly useful in harsh environments which  
may cause setup data loss such as battery failure. Upon such an error  
occurring, BIOS will check the data, and automatically restore the  
original data for booting.  
• Automatically power on after power failure: It is often required to  
have an unattended system come back to operation when power  
resumes after a power failure. Advantech's industrial motherboard  
allows users to set the system to power on automatically without push-  
ing the power on button.

1.7 Safety Precautions  
Warning!  
Always completely disconnect the power cord  
from your chassis whenever you work with the  
hardware. Do not make connections while the  
power is on. Sensitive electronic components  
can be damaged by sudden power surges. Only  
experienced electronics personnel should open  
the PC chassis.  
Caution! Always ground yourself to remove any static  
charge before touching the motherboard. Mod-  
ern electronic devices are very sensitive to  
static electric charges. As a safety precaution,  
use a grounding wrist strap at all times. Place  
all electronic components on a static-dissipative  
surface or in a static-shielded bag when they  
are not in the chassis.  
Caution! The computer is provided with a battery-pow-  
ered Real-time Clock circuit. There is a danger  
of explosion if battery is incorrectly replaced.  
Replace only with same or equivalent type rec-  
ommended by the manufacturer. Discard used  
batteries according to manufacturer's instruc-  
tions.  
Caution! There is a danger of a new battery exploding if  
it is incorrectly installed. Do not attempt to  
recharge, force open, or heat the battery.  
Replace the battery only with the same or  
equivalent type recommended by the manufac-  
turer. Discard used batteries according to the  
manufacturer’s instructions.

1.8 Jumper Settings  
This section provides instructions on how to configure your motherboard  
by setting the jumpers. It also includes the motherboards's default settings  
and your options for each jumper.  
1.8.1 How to set jumpers  
You can configure your motherboard to match the needs of your applica-  
tion by setting the jumpers. A jumper is a metal bridge that closes an elec-  
trical circuit. 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” (or turn ON) a jumper, you connect the pins with the clip. To  
“open” (or turn OFF) a jumper, you remove the clip. Sometimes a jumper  
consists of a set of three pins, labeled 1, 2, and 3. In this case you connect  
either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be useful  
when setting jumpers.  
1.8.2 CMOS clear (J1)  
The AIMB-760 motherboard contains a jumper that can erase CMOS  
data and reset the system BIOS information. Normally this jumper should  
be set with pins 1-2 closed. If you want to reset the CMOS data, set J1 to  
2-3 closed for just a few seconds, and then move the jumper back to 1-2  
closed. This procedure will reset the CMOS to its default setting.

1.8.3 Watchdog timer output (J2)  
The AIMB-760 contains a watchdog timer that will reset the CPU or send  
a signal to IRQ11 in the event the CPU stops processing. This feature  
means the AIMB-760 will recover from a software failure or an EMI  
problem. The J2 jumper settings control the outcome of what the com-  
puter will do in the event the watchdog timer is tripped.

1.9 System Memory  
The AIMB-760 has four sockets for 240-pin dual inline memory modules  
(DIMMs) in two memory channels.  
All these sockets use 1.8 V unbuffered double data rate synchronous  
DRAMs (DDR SDRAM). They are available in capacities of 256, 512  
and 1024 MB. The sockets can be filled in any combination with DIMMs  
of any size, giving a total memory size between 256 MB and 4 GB.  
1.9.1 CPU FSB and memory speed  
The AIMB-760 can accept DDR2 SDRAM memory chips without parity.  
Also note: The AIMB-760 accepts DDR2 400MHz SDRAM, and DDR2  
533 MHz SDRAM. The AIMB-760 does NOT support ECC (error check-  
ing and correction).  
1.10 Memory Installation Procedures  
To install DIMMs, first make sure the two handles of the DIMM socket  
are in the “open” position. i.e. The handles lean outward. Slowly slide the  
DIMM module along the plastic guides on both ends of the socket. Then  
press the DIMM module right down into the socket, until you hear a  
click. This is when the two handles have automatically locked the mem-  
ory module into the correct position of the DIMM socket. To remove the  
memory module, just push both handles outward, and the memory mod-  
ule will be ejected by the mechanism in the socket.  
1.11 Cache Memory  
Since the second-level (L2) cache has been embedded into the Intel®  
LGA-775-socket Pentium® 4 / Celeron® D processor. The built-in sec-  
ond-level cache in the processor yields much higher performance than the  
external cache memories. The cache size in the Intel® Pentium® 4 pro-  
cessor is 1024/2048 KB. In the Celeron D CPU, the cache size is 256 KB.

Chapter 2 Connecting Peripherals  
2.1 Introduction  
You can access most of the connectors from the top of the board while it  
is installed in the chassis. If you have a number of cards installed or have  
a packed chassis, you may need to partially remove the card to make all  
the connections.  
2.2 Primary (CN1) IDE Connector  
You can attach up to four IDE (Integrated Drive Electronics) drives to the  
AIMB-760’s built-in controller. The primary (CN1) connector can each  
accommodate two drives.  
Wire number 1 on the cable is red or blue and the other wires are gray.  
Connect one end to connector CN1 on the motherboard. Make sure that  
the red/blue wire corresponds to pin 1 on the connector (in the upper right  
hand corner). See Chapter 1 for help finding the connector.  
Unlike floppy drives, IDE hard drives can connect in either position on  
the cable. If you install two drives to a single connector, you will need to  
set one as the master and the other as the slave. You do this by setting the  
jumpers on the drives. If you use just one drive on the connector, you  
should set the drive as the master. See the documentation that came with  
your drive for more information.  
Connect the first hard drive to the other end of the cable. Wire 1 on the  
cable should also connect to pin 1 on the hard drive connector, which is

Chapter 3 Award BIOS Setup  
3.1 Introduction  
Award’s BIOS ROM has a built-in setup program that allows users to  
modify the basic system configuration. This type of information is stored  
in battery backed-up memory (CMOS RAM) so that it retains the setup  
information when the power is turned off.  
3.1.1 CMOS RAM Auto-backup and Restore  
The CMOS RAM is powered by an onboard button cell battery. When  
you finish BIOS setup, the data in CMOS RAM will be automatically  
backed up to Flash ROM. If operation in harsh industrial environments  
causes a soft error, BIOS will recheck the data in CMOS RAM and auto-  
matically restore the original data in Flash ROM to CMOS RAM for  
booting.  
Note:  
If you intend to change the CMOS setting with-  
out restoring the previous backup, you have to  
click on “DEL” within two seconds of the  
“CMOS checksum error...” display screen mes-  
sage appearing. Then enter the “Setup” screen  
to modify the data. If the “CMOS checksum  
error...” message appears again and again,  
please check to see if you need to replace the  
battery in your system.  
3.2 Entering Setup  
Turn on the computer and press <Del> to enter the BIOS setup.

Watchdog Timer  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Appendix A Watchdog Timer  
A.1 Programming the Watchdog Timer  
The AIMB-760's watchdog timer can be used to monitor system software  
operation and take corrective action if the software fails to function  
within the programmed period. This section describes the operation of the  
watchdog timer and how to program it.  
A.1.1 Watchdog timer overview  
The watchdog timer is built in to the super I/O controller W83627HF. It  
provides the following functions for user programming:  
• Can be enabled and disabled by user's program  
• Timer can be set from 1 to 255 seconds or 1 to 255 minutes  
• Generates an interrupt or resets signal if the software fails to reset the  
timer before time-out  
A.1.2 Reset/Interrupt selection  
The J2 jumper is used to select reset or interrupt (IRQ 11) in the event the  
watchdog timer is tripped. See Chapter 1 for detailed jumper settings.  
Note:  
The interrupt output of the watchdog timer is a  
low level signal. It will be held low until the  
watchdog timer is reset.  
A.1.3 Programming the Watchdog Timer  
The I/O port address of the watchdog timer is 2E(hex) and 2F(hex).  
2E (hex) is the address port. 2F(hex) is the data port. You must first  
assign the address of register by writing an address value into address  
port 2E (hex), then write/read data to/from the assigned register through  
data port 2F (hex).
