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 mount-
ing chassis. It meets the requirements of a variety of applications where a
commercial motherboard cannot fit.
The AIMB-742 uses Intel's 865G 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 per-
formance VGA interface, dual Giga-bit Ethernet ports, dual channel Ultra
160 SCSI interface, eight USB 2.0 ports (up to 480 Mbps), and other stan-
dard 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 pro-
gram 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,
