1.2 Features

1. Standard ATX form factor with industrial features: AIMB-740/

741 provides industrial features like long product life, reliable oper-

ation under wide temperature range, watchdog timer, CMOS

backup functions, etc.

2. PCI and ISA bus support: in addition to the 5 PCI slots, AIMB-

740/741 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 sys-

tem 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 environ-

ments which may cause setup data loss such as battery failure.

Upon such an error occurring, BIOS will check the data, and auto-

matically 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.
