1.0.2 Product warranty

Advantech warrants to you, the original purchaser, that each of its prod­ucts 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 instal­lation. 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 prod­uct 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.

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 mount­ing 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 pro­gram 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.

1.2 Features

1. Standard ATX form factor with industrial features: AIMB-744
provides industrial features like long product life, reliable operation
under wide temperature range, watchdog timer, CMOS backup
functions, etc.

2. PCI-X and PCI bus support: AIMB-744 equips with two 64-bit
PCI-X (66MHz) slots and 4 32-bit PCI slots , providing the high
performance computing systems.

3. 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 sys­tem to be managed through Ethernet when it is connected to the
SNMP-1000 Remote HTTP/SNMP System Manager.

4. 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.

5. 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. Mod­ern 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 rec­ommended by the manufacturer. Discard used
batteries according to manufacturer's instruc­tions.

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 manufac­turer. 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 applica­tion by setting the jumpers. A jumper is a metal bridge that closes an elec­trical 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.

Table 1.3: CMOS (J1)

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

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.

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 phys­ical memory address locations that reduce available memory
addresses above 3GB. This may result in less than 4GB of mem­ory 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 relation­ship between the CPU FSB and memory speed.

Table 1.7: CPU FSB and memory speed

AIMB-744 User’s Manual 14

Memory
Speed

DDR400 Pentium 4 800 MHz 400 MHz

DDR333 Pentium 4 800 MHz 320 MHz

DDR266 Pentium 4 533 or 400 MHz 266 MHz

Processor FSB frequency Memory speed Outcome

Pentium 4 533MHz 333 MHz

Pentium 4
or Celeron

Celeron 400 MHz 266 MHz

400 MHz 266 MHz

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 (pur­ple 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 mem­ory module into the correct position of the DIMM socket. To remove the
memory module, just push both handles outward, and the memory mod­ule 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®
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.
