The integrated power management module incorporates the ACPI 1.0b compliance functions, the APM 1.2

compliance functions, and the PCI bus power management interface spec. v1.1. Numerous power-up events and

power down events are also supported. 21 general purposed I/O pins are provided to give an easy to use logic for

specific application. In addition, the Intel 82801DBM ICH4-M supports Deeper Sleep power state for Intel Mobile

processor.

A high bandwidth and mature Intel®’ I/O Hub architecture is incorporated to connect Montara and Intel 82801DBM

ICH4-M Hub interface together. Intel®’ I/O Hub architecture is developed.
