1.0.2 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:  
Step 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.  
Step 2. Call your dealer and describe the problem. Please have your man-  
ual, product, and any helpful information readily available.  
Step 3. 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.  
v
Step 4. 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 prod-  
uct returned without proof of the purchase date is not eligible for  
warranty service.  
Step 5. Write the RMA number visibly on the outside of the package and  
ship it prepaid to your dealer.

General Information  
Chapter 1 Hardware Configuration  
1.1 Introduction  
Advantech's AIMB-744 series industrial motherboard is designed based  
on the standard ATX form factor with additional industrial features such  
as long product life, high reliability and manageability. It is flexible to be  
installed in a commercial PC chassis or in an industrial grade rack mount-  
ing chassis. It meets the requirements of a variety of applications where a  
commercial motherboard cannot fit.  
The AIMB-744 uses Intel's 875P with 6300ESB chipset to support Intel's  
Socket 478 Pentium 4 and Celeron processor with 800/533/400 MHz  
front side bus. The dual channel DDR 400 SDRAM interface provides  
bottleneck free memory bandwidth up to 6.4GB/s. In addition to the two  
EIDE interfaces (up to four devices), it features a high performance serial  
ATA interface (up to 150MB/s) which eases cabling to hard drives in  
industrial chassis with thin and long cables. Other features include two  
64-bit PCI-X (66MHz) slots, dual Giga-bit Ethernet ports, dual channel  
Ultra 160 SCSI interface, four USB 2.0 ports (up to 480 Mbps), and other  
standard PC functions like four RS-232 serial port interfaces, one  
enhanced parallel port and floppy disk interface.  
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-744 to be managed  
through Ethernet when it is connected to the SNMP-1000 Remote HTTP/  
SNMP System Manager.  
Note:  
Some of the features mentioned above are not  
available with all models. For more information  
about the specifications of a particular model,  
see Table 1.1 : Comparison table and Section  
1.3: Specifications.

PCI-X (66MHz) slots and 4 32-bit PCI slots , providing the high  
performance computing systems.  
Healthy status monitoring and remote management: System  
voltage levels, fan speed, CPU temperature are monitored to ensure  
stable operation. The remote management interface allows the sys-  
tem to be managed through Ethernet when it is connected to the  
SNMP-1000 Remote HTTP/SNMP System Manager.  
4.  
5.  
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 environ-  
ments which may cause setup data loss such as battery failure.  
Upon such an error occurring, BIOS will check the data, and auto-  
matically 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  
pushing 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-744 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-744 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-744 will recover from a software failure or an EMI  
AIMB-744 User’s Manual

problem. The J2 jumper settings control the outcome of what the com-  
puter will do in the event the watchdog timer is tripped.

Note:  
The interrupt output of the watchdog timer is a  
low level signal. It will be held low until the  
watchdog timer is reset.  
1.8.4 PCI-X 33/66Mhz selection (J5 & J6)  
The AIMB-744 contains a PCI-X 33/66Mhz selection that enables the  
PCI-X slots different modes. The default mode is PCI 33MHz which  
close both J5 and J6. While close J6 only the slots work in PCI 66MHz  
mode. To enable PCI-X 66MHz mode, please close J5 only.

The AIMB-744 contains a PCI-X 3.3V/5V selection that provide the user  
to select the operation voltage either 3.3V or 5V. The default setting is  
3.3V which close pin1 and pin2. By closing pin2 and pin3, the operation  
voltage change to 5V.

1.9 System Memory  
The AIMB-744 has four sockets for 184-pin dual inline memory modules  
(DIMMs) in two separated memory channels. It can operate with single  
channel or dual channel modules. We recommend to use dual channel  
mode to provide optimized performance.  
All these sockets use 2.5 V unbuffered double data rate synchronous  
DRAMs (DDR SDRAM). They are available in capacities of 128, 256,  
512 and 1024 MB. The sockets can be filled in any combination with  
DIMMs of any size, giving a total memory size between 128 MB and 4  
GB.  
Note: System resources such as PCI and AGP cards require phys-  
ical memory address locations that reduce available memory  
addresses above 3GB. This may result in less than 4GB of mem-  
ory being available to the operating system and applications.  
1.9.1 CPU FSB and memory speed  
The AIMB-744 can accept DDR SDRAM memory chips without parity.  
Also note: The AIMB-744 accepts PC2100 (DDR266), PC2700 (DDR  
333) and PC3200 (DDR 400) DDR SDRAM, depending on the CPU  
front side bus frequency (FSB). Please refer below table for the relation-  
ship between the CPU FSB and memory speed.

The AIMB-744 does not support ECC (error checking and correction).  
Memory modules with 9 SDRAM chips/side support ECC; modules with  
8 chips/side do not support ECC.  
1.9.2 Dual channel configuration  
The four DIMM sockets are arranged in two channels: DIMM1 &  
DIMM2 in channel A; DIMM3 & DIMM4 in channel B. To enable dual  
channel operation, please install a matched pair of DIMMs in DIMM1 &  
DIMM3 (green sockets). If additional memory is to be used, another  
matched pair of DIMMs have to be installed in DIMM2 & DIMM4 (pur-  
ple sockets).  
"Matched pair of DIMMs" means: same in speed (DDR266, DDR333,  
DDR400), same in size (128MB, 256MB, 512MB or 1GB), same in chip  
density (128 Mb, 256Mb or 512Mb and same in CSA latency. Any other  
memory configuration will result in single channel memory operation.  
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.  
15  
1.11 Cache Memory  
Since the second-level (L2) cache has been embedded into the Intel®  
socket 478 Pentium® 4/Celeron™ processor, you do not have to take  
care of either SRAM chips or SRAM modules. The built-in second-level  
cache in the processor yields much higher performance than the external  
cache memories. The cache size in the Intel ® Pentium ® 4 processor is  
512/1024 KB. In the Celeron CPU, the cache size is 128/256KB.  
1.12 Processor Installation  
The AIMB-744 is designed for Intel Pentium® 4 processor/Celeron™  
(socket 478) up to 3.4/2.8 GHz with HT technology.  
Note:  
Slim Heatsink & Fan is available from Advan-  
tech. Please contact with Advantech's sales  
representative if needed.

Connecting  
Peripherals  
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) and Secondary (CN2) IDE Connec-  
tors  
CN1  
CN2  
You can attach up to four IDE (Integrated Drive Electronics) drives to the  
AIMB-744’s built-in controller. The primary (CN1) and secondary (CN2)  
connectors 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 or CN2 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 per connector, you should  
set each 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  
labeled on the drive circuit board. Check the documentation that came  
with the drive for more information.  
AIMB-744 User’s Manual  
18  
Connect the second hard drive to the remaining connector (CN2 or CN1),  
in the same way as described above. The secondary IDE shares the same  
resource with CF (CompactFlash) socket. CF card is only available for  
master mode. While setting CF as master, the other IDE device con-  
nected to secondary IDE can work as a slave device only and vice versa.  
2.3 Floppy Drive Connector (CN3)  
CN3  
You can attach up to two floppy disk drives to the AIMB-744's onboard  
controller. You can use 3.5" (720 KB, 1.44 MB) drives.  
The motherboard comes with a 34-pin daisy-chain drive connector cable.  
On one end of the cable is a 34-pin flat-cable connector. On the other end  
are two sets of 34-pin flat-cable connector (usually used for 3.5" drives).  
The set on the end (after the twist in the cable) connects to the A: floppy  
drive. The set in the middle connects to the B: floppy drive.  
2.4 Parallel Port (CN4)  
CN4  
The parallel port is normally used to connect the motherboard to a printer.  
The AIMB-744 includes an onboard parallel port, accessed through a 26-  
pin flat-cable connector, CN4.  
19

2.5 USB Ports (CN6; shared with CN32)  
CN6/CN63  
The AIMB-744 provides up to four ports of USB (Universal Serial Bus)  
interface, which gives complete Plug & Play and hot swapping for up to  
127 external devices.The USB interface complies with USB Specification  
Rev. 2.0 support transmission rate up to 480 Mbps and is fuse-protected.  
The USB interface can be disabled in the system BIOS setup.  
Limitation: On 00A1 version, when CN6 is used, both transmission rates  
of CN6 and CN32 will drop to 24 Mbps.  
2.6 Serial Ports (COM1 : CN9; COM2 : CN38 ; COM3 :  
CN10 ; COM4 : COM23)  
CN9  
CN10  
The AIMB-744 offers two serial ports and two onboard connectors, CN9  
as COM1, CN38 as COM2, CN10 as COM3 and CN23 as COM4. These  
ports can connect to serial devices, such as a mouse or a printer, or to a  
communications network.  
The IRQ and address ranges for both ports are fixed. However, if you  
want to disable the port or change these parameters later, you can do this  
in the system BIOS setup.  
AIMB-744 User’s Manual  
20  
Different devices implement the RS-232 standard in different ways. If  
you are having problems with a serial device, be sure to check the pin  
assignments for the connector.  
2.7 PS/2 Keyboard and Mouse Conn (CN11)  
CN11  
Two 6-pin mini-DIN connectors (CN11) on the motherboard provide  
connection to a PS/2 keyboard and a PS/2 mouse, respectively.  
2.8 External Keyboard Connector (CN12)  
CN12  
In addition to the PS/2 mouse/keyboard connector on the AIMB-744's  
rear plate, there is also an extra onboard external keyboard connector.  
This gives system integrators greater flexibility in designing their sys-  
tems.

Award BIOS Setup  
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 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 environment  
cause 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.

Chapter 4 Chipset Software Install Utility  
4.1 Before you begin  
To facilitate the installation of the enhanced display device drivers and  
utility software, you should read the instructions in this chapter carefully  
before you attempt installation. The device drivers for the AIMB-744  
board are located on the software installation CD. The auto-run function  
of the driver CD will guide and link you to the utilities and device drivers  
under a Windows system. The Intel® Chipset Software Installation Util-  
ity is not required on any systems running Windows NT 4.0. Updates are  
provided via Service Packs from Microsoft*.  
Note:  
The files on the software installation CD are  
compressed. Do not attempt to install the driv-  
ers by copying the files manually. You must use  
the supplied SETUP program to install the driv-  
ers.  
Before you begin, it is important to note that most display drivers need to  
have the relevant software application already installed in the system  
prior to installing the enhanced display drivers. In addition, many of the  
installation procedures assume that you are familiar with both the rele-  
vant software applications and operating system commands. Review the  
relevant operating system commands and the pertinent sections of your  
application software’s user’s manual before performing the installation.  
4.2 Introduction

6.1 Introduction  
The AIMB-744's hardware monitor is designed with Winbond W83782D.  
Onboard security (OBS) functions monitor key hardware. They help you  
maintain your system's stability and durability. The AIMB-744 can moni-  
tor 5 sets of system positive voltages, 2 sets of system negative voltages,  
CPU cooling fan speed, and CPU temperature. The positive system volt-  
age sets which can be monitored include:  
• CPU core voltage: 1.3 V ~ 3.3 V, according to Intel specifications.  
• Transmission voltage from CPU to chipset: typically 1.8 V.  
• Chipset voltage: typically 3.3 V.  
• Main voltage: +5 V, +12 V.  
The negative system voltage sets which can be monitored include:  
• Main voltage: -5 V, -12 V.

After completing the setup, all the OBS functions are permanently  
enabled. When a monitored reading exceeds safe limits, a warning mes-  
sage will be displayed and an error beep tone will activate to attract your  
attention.  
OBS Hardware Doctor will show an icon on the right side of the bottom  
window bar. This icon is the "Terminate and Stay Resident" (TSR) icon.  
It will permanently remain in the bottom window bar, and will activate  
warning signals when triggered by the onboard security  
system.  
You can view or change values for various OBS settings by running this  
utility:  
1.  
From the desktop of Windows, click on "Start" and select "Pro-  
grams" , select "Winbond HWDoctor" and click "HWDOCTOR."  
2.  
It is recommended that you load the default values for all the OBS  
settings. However, if desired, you can establish new conditions for  
voltage, fan speed, and temperature.

Programming the  
Watchdog Timer  
Appendix A Programming the watchdog  
timer  
A.1 Programming the Watchdog Timer  
The AIMB-744's watchdog timer can be used to monitor system software  
operation and take corrective action if the software fails to function after  
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 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 after 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 address value  
into address port 2E(hex), then write/read data to/from the assigned  
register through data port 2F (hex).

how long the watchdog  
timer waits for strobe  
before generating an inter-  
rupt or reset signal. Writing  
a new value to this register  
can reset the timer to count  
with the new value.
