1.1 Introduction
The AIMB-766 is the most advanced Intel Q35 product for industrial applications that
require high-performance computing. The motherboard supports Intel Core 2 Duo /
Core 2 Quad / Pentium Dual Core / Celeron processors with 800/1066/1333 MHz
front side bus and DDR2 667/ 800 MHz memory up to 8 GB.
The AIMB-766 incorporates the Intel Q35 chipset to offer cost-effective integrated
graphics. The Q35 chipset uses the Intel Extreme Graphics architecture (GMA 3100)
to maximize VGA performance and share up to 256 MB of system memory. When
higher graphics performance is needed, the AIMB-766 provides a mainstream PCIe
x16 expansion slot for add-on graphic cards. In addition, the AIMB-766 has a single/
dual Gigabit Ethernet LAN via a dedicated PCIe x1 bus, which offers bandwidth of up
to 500 MB/s, eliminating network bottlenecks. High reliability and outstanding perfor-
mance make the AIMB-766 the idea platform for industrial networking applications.
By using the Intel ICH9 DO chipset, the AIMB-766 offers four 32-bit, 33 MHz PCI
slots; two PCIe x1 slot, one PCIe x16 slot and a variety of features such as 6 on-
board SATA II interfaces (bandwidth = 300 MB/s) with software for RAID 0, 1, 10 and
5; 12 USB 2.0 connections; 1 ATA 100/66/33 port; and HD Audio. These powerful I/O
capabilities ensure even more reliable data storage capabilities and high-speed I/O
peripheral connectivity.
The AIMB-766 also adopts Advantech’s unique patented “Sleep Mode Control Cir-
cuit” for AT Power Mode.
With all the excellent features and outstanding performance, the AIMB-766 is defi-
nitely the ideal platform for today’s industrial applications.

1.2 Features
!
!
!
PCIe architecture: The Intel Q35 and ICH9 DO (or ICH9) PCIe chipset sup-
ports 1 PCIe x16 slot, 2 PCIe x1 slot and a PCIe x1 link for the Gigabit LAN.
High Performance I/O Capability: Dual/single Gigabit LAN via PCIe x1 bus, 4
PCI 32-bit/33MHz PCI slots, 6 SATA2 connectors and 12 USB 2.0 ports.
Standard ATX form factor with industrial features: AIMB-766 provides indus-
trial features like long product life, reliable operation under wide temperature
range, watchdog timer, CMOS backup functions, etc.
!
BIOS CMOS backup and restore: When BIOS CMOS setup has been com-
pleted, 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, the 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 pushing the power on button.
Active Management Technology 3.0: The hardware and firmware base solu-
tion (ICH9 DO only, for AIMB-766G2-00A1E sku only) is powered by the system
auxiliary power plane to remotely monitor networked systems. Intel AMT stores
hardware and software information in non-volatile memory. Built-in management
provides out-of-band management capabilities, allowing remote discoverery
and repair of systems after OS failures or when a system is powered down.
Alert and event logging features detect problems and quickly reduce downtime,
pro-actively blocking incoming threats, containing infected clients before they
impact the network, and proactively notifying the user when critical software
agents are removed.

1.7 Safety Precautions
Warning! Always completely disconnect the power cord from your chassis when-
ever you work with the hardware. Do not make connections while the
power is on. Sensitive electronic components can be damaged by sud-
den 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 cir-
cuit. There is a danger of explosion if battery is incorrectly replaced.
Replace only with same or equivalent type recommended by the manu-
facturer. 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 man-
ufacturer. Discard used batteries according to the manufacturer’s

1.8 Jumper Settings
This section provides instructions on how to configure your motherboard by setting
the jumpers. It also includes the motherboard 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 set-
ting 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 set-
ting jumpers.
1.8.2 CMOS clear (CMOS1)
The AIMB-766 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 sec-
onds, 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 (JWDT1)
The AIMB-766 contains a watchdog timer that will reset the CPU. This feature means
the AIMB-766 will recover from a software failure or an EMI problem. The
JSETCOM2 jumper settings control the outcome of what the computer will do in the
event the watchdog timer is tripped.

1.9 System Memory
The AIMB-766 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 1024 and 2048 MB. The sock-
ets can be filled in any combination with DIMMs of any size, giving a total memory
size between 256 MB and 8 GB.
1.9.1 CPU FSB and memory speed
The AIMB-766 can accept DDR2 SDRAM memory chips without parity. Also note that
the AIMB-766 accepts DDR2 667/800 MHz SDRAM, and DDR2 SDRAM. The AIMB-
766 does not support ECC (error checking 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, and then press the DIMM module right
down into the socket, until you hear a click. This is when the two handles have auto-
matically 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 mod-
ule will be ejected by the mechanism in the socket.

2.1 Introduction
You can access most of the connectors from the top of the board as it is being
installed in the chassis. If you have a number of cards installed, you may need to par-
tially remove a card to make all the connections.
2.2 Primary (IDE1) IDE Connector
You can attach up to one IDE (Integrated Drive Electronics) drive to the AIMB-766’s
built-in controller.
Wire number 1 on the cable is red or blue and the other wires are gray. Connect one
end to connector IDE1 on the motherboard. Make sure that the red/blue wire corre-
sponds to pin 1 on the connector (in the upper right hand corner).
Connect the 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.

AMIBIOS has been integrated into many motherboards for over a decade. In the
past, people often referred to the AMIBIOS setup menu as BIOS, BIOS setup or
CMOS setup.
With the AMIBIOS Setup program, you can modify BIOS settings and control the
special features of your computer. The Setup program uses a number of menus for
making changes and turning the special features on or off. This chapter describes the
basic navigation of the AIMB-766 setup screens.
Figure 3.1 Setup program initial screen
AMI’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 CMOS
so it retains the Setup information when the power is turned off.
