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 manual, 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.
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

1.8 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-powered 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.

1.9 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.
1.9.1 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.
1.9.2 CMOS clear (J1)
The AIMB-740/741 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)

1.9.3 Watchdog timer output (J2)
The AIMB-740/741 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-740/741 will recover from a software failure or an
AIMB-740/741 User’s Manual
12
EMI problem. The J2 jumper settings control the outcome of what the
computer 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.
1.9.4 Riser card selection (J3 & J4)
The AIMB-740/741 contains a riser card selection that enables the riser
card function. While using 2U riser card, you should close pin 1 and pin 2
of J3 and J4 to activate the PCI slots on the riser card.

1.10 System Memory
The top-left edge of the AIMB-740/741 contains two sockets for 184-pin
dual in-line memory modules (DIMMs). Both two sockets use 2.5 V double-data-rate synchronous DRAMs (DDR SDRAM). DIMMs are available in capacities of 64, 128, 256, 512 MB, or 1 GB. The sockets can be
filled in any combination with DIMMs of any size, giving your AIMB740/741 single board computer between 64 MB and 2 GB of memory.
Use the following table to calculate the total DRAM memory within your
computer:

1.11 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.

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 and Secondary (CN1/2) IDE Connectors
CN1
CN2
You can attach up to four IDE (Integrated Drive Electronics) drives to the
AIMB-740/741’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.
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. CN61 is used to set CF as masAIMB-740/741 User’s Manual

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 automatically restore the original data in Flash ROM to CMOS RAM for
booting.
Note:
If you intend to change the CMOS setting without restoring the previous backup, you have to
click on "DEL" within two seconds of the
"CMOS checksum error..." display screen message 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 5 VGA Setup (for AIMB-740)
5.1 Introduction
The AIMB-740 has VGA onboard, you need to install the VGA driver to
enable the function.
The Intel® 845GV Graphics Memory Controller Hub (the 845GV
GMCH) is Intel’s first memory controller hub with integrated graphics
for the Intel Pentium® 4 processor. The 845GV GMCH, with its new
architecture graphics engine, delivers not only high 2D/3D graphics performance, but also provides efficient, high bandwidth communication
channels connecting the processor, the memory, the I/O subsystem, and
other components together to deliver a stable mainstream desktop platform solution. The features include:
• Built-in 2D/3D VGA controller.
• Use Intel® Extreme Graphics Architecture
• Integrated 350MHz RAMDAC that can directly drive a progressive
scan analog monitor up to a resolution of 2048x1536 at 60MHz
• Up to 1600 x 1200 x 32 resolution at 85 Hz refresh.
• H/W motion compensation assistance for s/w MPEG 2 decoding.
• Software DVD at 30 fps Full Screen.
Note :
1. It is strongly suggested to install DirectX 8.1 or later version if your
operating system is Windows 98.
2. The AIMB-740 is VGA integrated, the VGA driver will be installed
with the operating system. If you want to use an add-on VGA card, you
must remove theVGA driver first, then plug in the add-on VGA card
and install the driver for that.
5.2 Dynamic Video Memory Technology
The following is quoted from "Intel® 845GV Chipset Dynamic Video
Memory Technology" Rev. 1.2 June 2002”:
Dynamic Video Memory Technology (DVMT) is an enhancement of the
UMA concept, wherein the optimum amount of memory is allocated for
balanced graphics and system performance, through Direct AGP known
as Non-Local Video Memory (NLVM), and a highly efficient memory
AIMB-740/741 User’s Manual
54
utilization scheme. DVMT ensures the most efficient use of available
memory regardless of frame buffer or main memory sizing for maximum
2D/3D Graphics performance. DVMT dynamically responds to system
requirements, and applications demands, by allocating the proper amount
of display, texturing and buffer memory after the operating system has
booted. For example, a 3D application when launched may require more
vertex buffer memory to enhance the complexity of objects, or more texture memory to enhance the richness of the 3D environment. The operating system views the integrated graphics driver as an application, which
uses Direct AGP to request allocation of additional memory for 3D applications, and returns the memory to the operating system when no longer
required.
The Intel Extreme Graphics Driver determines the size of the pre-allocated memory needed and will make additional Non-Local Video Memory requests to achieve the amount needed for the display and application

This driver takes advantage of the latest Intel ® Ultra ATA controller features to improve both storage subsystem performance and overall system
performance. A useful diagnostic tool, Intel Ultra ATA Companion® ,
shows technical information of the ATA subsystem.
8.2 Features
• The driver enables fast Ultra ATA transfers by default.
• Users no longer have to manually enable DMA transfers for each
ATA and/or ATAPI peripheral devices.
• Each ATA channel has independent device timings/transfers which
allows PIO-only and DMA-capable devices to share the same
ATA controller cable, where one is the master and the other the
slave, without restricting transfer mode to PIO-only for both
devices.
• Technical details of the ATA subsystem can be viewed via use of the
application.
• Drivers are optimized.

Appendix A Programming the watchdog
timer
A.1 Programming the Watchdog Timer
The AIMB-740/741'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).
