Advanced Power Management - Intel VS440FX Technical Specification

VS440FX Motherboard Technical Product Specification
The BIOS support for DMI enables the maximum benefit from applications such as LANDesk
Client Manager from Intel. The BIOS stores and can report on the following types of DMI
information:
BIOS data, such as the BIOS revision level
Fixed system information, such as data about the motherboard, peripherals, serial numbers and
asset tags, etc.
System information discovered during bootup, such as memory size, cache size, processor
speed, etc.
Dynamic information, such as event detection and error logging
An OEM can use a utility that makes DMI calls to program system and chassis-related information
into the Flash memory, so the BIOS can also report that information. Once this information is
written, it is locked (read-only).
Intel can provide a utility for making DMI calls to the BIOS. Contact your local Intel Sales office
for further information. The latest DMI specification is available from Intel (refer to Section 5.2)
and other sites.
DMI does not work directly under non-Plug and Play operating systems (e.g., Windows NT).
However, the BIOS supports a DMI table interface for such OSs. Using this support, a DMI
service-level application running on a non-Plug and Play OS can access the DMI BIOS
information.

3.8 Advanced Power Management

The BIOS supports APM. You can initiate the energy saving Standby mode in these ways:
Keyboard hot key sequence specified in Setup
Time-out period specified in Setup
Suspend/resume switch connected to the front panel sleep connector
When in Standby mode, the motherboard reduces power consumption by using the processor's
System Management Mode (SMM) capabilities and by spinning down hard drives and reducing
power to or turning off VESA
mode to use for the monitor: Standby, Suspend, Sleep, or Disabled (Off).
While in Standby mode, the system retains the ability to respond to external interrupts; it can
service requests such as incoming faxes or network messages while unattended. Any keyboard or
mouse activity brings the system out of Standby mode and immediately restores power to the
monitor and IDE drives.
APM is enabled in the BIOS by default; however, the system must be configured with an APM
driver for the power-saving features to take effect. For example, Windows 95 enables APM
automatically upon detecting the presence of the APM BIOS.
