Chapter 1 Hardware Configuration
1.1 Introduction
Advantech's AIMB-760 is designed with the Intel 915GV and ICH6 PCI
Express chipset in an ATX form factor. Not only does it boast commercial PC performance but it also has industrial features such as reliability,
longevity, revision control and scalability. This product is ideal for customers who are using off-the-shelf commercial motherboards but need
industrial features. Designed with standardization and compatibility in
mind, the AIMB-760 can be installed in a variety of Advantech industrial
chassis or normal commercial chassis for various applications.
With the Intel 915GV and ICH6 chipset architecture, AIMB-760 has an
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 system 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 onboard 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 program 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.
AIMB-760 User Manual 2
1.2 Features
• PCI Express architecture: Designed with the Intel 915GV and ICH6
PCI-Express chipset, the AIMB-760 has dual/single Gigabit LAN via
PCI-E x1 bus and 2 PCI-E x1 slots (one for riser card).
• High Performance I/O Capability: Dual/single Gigabit LAN via PCIE x1 bus, 2 PCI-E x1 slots (one for riser card), 5 PCI 32-bit/33MHz
PCI slots, 4 SATA connectors and 8 USB 2.0 ports.
• Standard ATX form factor with industrial features: AIMB-760 pro-
vides industrial features like long product life, reliable operation under
wide temperature range, watchdog timer, CMOS backup functions, etc.
• 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.
• 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

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-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.
Table 1.3: CMOS (J1)

1-2 closed
2-3 closed
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 computer 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 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. 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®
LGA-775-socket Pentium® 4 / Celeron® D processor. 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 1024/2048 KB. In the Celeron D CPU, the cache size is 256 KB.
AIMB-760 User Manual 14
1.12 Processor Installation
The AIMB-760 is designed for Intel Pentium® 4 processor / Celeron® D
(LGA 775 socket) up to 3.8/3.06 GHz.
Step 1: Pull the bar besides the CPU socket outward and lift it.
Step 2: Align the triangular marking on the processor with the cut edge of
the socket.
