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.
This device complies with the requirements in part 15 of the FCC rules: Operation is subject to the following two conditions: 1.This device may not cause harmful interference, and 2.This device must accept any interference received, including interference that may cause undesired operation This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules.
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.
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) Function Jumper Setting IRQ11 1 1-2 closed * Reset 1 2-3 closed * default setting Note: The interrupt output of the watchdog timer is a low level signal. It will be held low until the watchdog timer is reset. 1.8.
1.8.5 PCI-X slots 3.3V/5V selection (J8) The AIMB-744 contains a PCI-X 3.3V/5V selection that provide the user 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. Table 1.6: PCI-X slots 3.3V/5V selection (J8) Function Jumper Setting *3.3V 1-2 Closed 5V 2-3 Closed 1.9 System Memory The AIMB-744 has four sockets for 184-pin dual inline memory modules (DIMMs) in two separated memory channels.

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.
CHAPTER 2 Connecting Peripherals 17 Chapter 2
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-744’s built-in controller.
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. CF card is only available for master mode. While setting CF as master, the other IDE device connected to secondary IDE can work as a slave device only and vice versa. 2.3 Floppy Drive Connector (CN3) CN3 You can attach up to two floppy disk drives to the AIMB-744's onboard controller. You can use 3.5" (720 KB, 1.44 MB) drives.

CN16 is a 5-pin connector for the power on LED. Refer to Appendix B for detailed information on the pin assignments. If a PS/2 or ATX power supply is used, the system's power LED status will be as indicated below: Table 2.1: PS/2 or ATX power supply LED status Power mode LED (PS/2 power) LED (ATX power) System On On On System Suspend Fast flashes Fast flashes System Off Off Slow flashes 2.11.2 External speaker (CN17) CN17 is a 4-pin connector for an extenal speaker.
2.11.6 SM Bus Connector (CN29) This connector is reserved for Advantech's SNMP-1000 HTTP/SNMP Remote System Manager. The SNMP-1000 allows users to monitor the internal voltages, temperature and fans from a remote computer through an Ethernet network. CN29 can be connected to CN19 of SNMP-1000. Please be careful about the pin assignments, pin 1 must be connected to pin 1 and pin2 to pin 2 on both ends of cable. 2.12 H/W Monitor Alarm (CN22) To enable or disable the function of buzzer. 2.
The AIMB-744 is equipped with one or two high-performance 10/100/ 1000 Mbps Ethernet LANs. They are supported by all major network operating systems. The RJ-45 jacks on the rear plate provide convenient or 10/100/1000 Base-T operation. 2.14 Line Out, Mic IN connector (CN55) The Line Out is to output the audio signal to external audio device, like speakers or headphones. The Mic IN is to input the audio signal via microphones. 2.
2.16 Aux Line-In connector (AUX IN; CN57) The connector is for audio device with Line-in connector. 2.17 Front Panel audio connector (FP AUDIO; CN59) The FPAUDIO is a front panel audio connector compliant with Intel® Front Panel I/O Connectivity Design Guide. To direct the audio signal output to the rear audio ports, the 5 and 6 pins, 9 and 10 pins must be shorted by jumper to activate the rear panel audio function.
2.18 8-pin Alarm Board Connector (CN62) The 8-pin alarm board connector is for Advantech chassis with alarm board. 2.19 Case Open Connector (CN64) The 2-pin case open connector is for chassis with case open censor. While opening the case, the buzzer on motherboard will ring. 2.
which eases cabling to hard drives with thin and long cables. 2.21 Connecting to SNMP-1000 remote manager Use the 6-pin to 8-pin cable to connect the motherboard to SNMP-1000. This cable comes with the SNMP-1000. 2.22 Auxiliary 4-pin power connector (ATX1) To ensure the sufficiency of power supply for Pentium® 4 motherboard, one auxiliary 4 pin power connector is available on AIMB-744. ATX1 must be used to provide sufficient 12V to ensure the stable operation of the system.
CHAPTER 3 Award BIOS Setup 29 Chapter 3
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.
3.2 Entering Setup Turn on the computer and press to allow you to enter the BIOS setup. Figure 3.1: Award BIOS Setup initial screen 3.3 Standard CMOS Setup Choose the “Standard CMOS Features” option from the “Initial Setup Screen” menu, and the screen below will be displayed.
