CHAPTER

General Information

Chapter 1 Hardware Configuration

1.1 Introduction

Advantech's AIMB-742 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-742 uses Intel's 865G/865GV 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 chipset built-in high performance VGA interface, dual Giga-bit Ethernet ports, eight USB 2.0 ports (up to 480 Mbps), and other standard PC functions like two RS-232 serial ports, 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-742 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.

AIMB-742 User’s Manual 2

1.2 Features

1. Standard ATX form factor with industrial features: AIMB-742 provides industrial features like long product life, reliable operation under wide temperature range, watchdog timer, CMOS backup functions, etc.

2. PCI and ISA bus support: in addition to the 5 PCI slots, AIMB742 provides 2 ISA slots, allowing existing ISA legacy devices to be used in modern high performance computing system.

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.

This device complies with the requirements in part 15 of the FCC rule.F

Operation is subject to be following two conditions.F

1.) This device may not cause harmful interference, and

2.) This device must accept any interference received,

including interference that may cause undesired operation.

AIMB-742 User’s Manual 10

Caution! Danger of explosion if battery in correctly replaced.

The battery need not to be charged.

Replace only with Advantech-specified batteries.

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-742 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)

Function Jumper Setting

* Keep CMOS data

1.8.3 Watchdog timer output (J2)

The AIMB-742 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-742 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.

Table 1.4: Watchdog timer output (J2)

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 System Memory

The AIMB-742 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,

AIMB-742 User’s Manual 12

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.

Limitation: The system configuration does not show the memory bank when booting.

1.9.1 CPU FSB and memory speed

The AIMB-742 can accept DDR SDRAM memory chips without parity. Also note: The AIMB-742 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 1.5: CPU FSB and memory speed

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-742 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 256/512/1024 KB. In the Celeron CPU, the cache size is 128/256KB.

1.12 Processor Installation

The AIMB-742 is designed for Intel Pentium® 4 processor/Celeron™ (socket 478)

Note: Slim Heatsink & Fan is available from Advan-

tech. Please contact with Advantech's sales representative if needed.

Step 1 : Lift the processor socket lever

Step 2 : Align the corner having the triangle marking on the processor

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 Connectors

CN1

CN2

You can attach up to four IDE (Integrated Drive Electronics) drives to the AIMB-742’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

5.1 Introduction

The AIMB-742 has VGA onboard, you need to install the VGA driver to enable the function.

The Intel® 865G/865GV Graphics Memory Controller Hub (the 865G/ 865GV GMCH) provides an integrated graphics accelerator delivering cost competitive 3D, 2D, and video capabilities. The GMCH contains an extensive set of instructions for 3D operations, BLT and Stretch BLT operations, motion compensation, overlay, and display control. The 865G/865GV GMCH’s video engines support video conferencing and other video applications. The GMCH does not support a dedicated local graphics memory interface; it may only be used in a UMA configuration. 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 75Hz

• Maximum 3D resolution supported : 1600 x 1200 x 32 @ 85Hz.

• H/W motion compensation assistance for s/w MPEG 2 decoding.

• Software DVD at 30 fps Full Screen.

5.2 Dynamic Video Memory Technology

The following is quoted from "Intel® 865G/865GV Chipset Dynamic Video Memory Technology", document number : 253144-001 :

The method of memory allocation where the Operating System, Application and Graphics Memory come from a unified System Memory pool known as Unified Memory Architecture (UMA).

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, or NLVM), and a highly efficient memory 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.

AIMB-742 User’s Manual 56

DVMT dynamically responds to system requirements, and application 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 (OS) 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 requirement. The video memory size in the Intel® 865G/865GV chipset varies and is determined using several factors. The key factors are system resources and system activity. The maximum video memory is up to 64MB SDRAM

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

01~FF (hex): The amount of the count, in seconds or minutes, depends on the value set in register F5 (hex). This number decides how long the watchdog timer waits for strobe before generating an interrupt or reset signal. Writing a new value to this register can reset the timer to count with the new value.
