AIMB-744 User’s Manual 2
Chapter 1 Hardware Configuration
1.1 Introduction
Advantech's AIMB-744 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-744 uses Intel's 875P with 6300ESB 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 two
64-bit PCI-X (66MHz) slots, dual Giga-bit Ethernet ports, dual channel
Ultra 160 SCSI interface, four USB 2.0 ports (up to 480 Mbps), and other
standard PC functions like four RS-232 serial port interfaces, 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-744 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
