Desktop Management Interface (DMI)
Desktop Management Interface (DMI) is an interface for managing computers in an
enterprise environment. The main component of DMI is the management
information format (MIF) database, which contains information about the computing
system and its components. Using DMI, a system administrator can obtain the
system types, capabilities, operational status, and installation dates for system
components. The MIF database defines the data and provides the method for
accessing this information. The BIOS enables applications such as Intel LANDesk®
Client Manager to use DMI. The BIOS stores and reports the following DMI
information:
−
BIOS data, such as the BIOS revision level.
−
Fixed-system data, such as peripherals, serial numbers, and asset tags.
−
Resource data, such as memory size, cache size, and processor speed.
−
Dynamic data, such as event detection and error logging.
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 operating
systems. Using this support, a DMI service-level application running on a non-Plug
and Play OS can access the DMI BIOS information.
Advanced Power Management (APM)
The BIOS supports APM and standby mode. The energy saving standby mode can
be initiated in the following ways:
−
Time-out period specified in Setup.
−
Suspend/resume switch connected to the front panel sleep connector.
−
From the operating system, such as the Suspend menu item in Windows 95.
In standby mode, the motherboard reduces power consumption by using SMM
capabilities, spinning down hard drives, and reducing power to or turning off VESA
DPMS-compliant monitors. Power-management mode can be enabled or disabled in
Setup.
While in standby mode, the system retains the ability to respond to external
interrupts and service requests, such as incoming faxes or network messages. Any
keyboard or mouse activity brings the system out of standby mode and immediately
restores power to the monitor.
The BIOS enables APM by default, but the operating system must support an APM
driver for the power-management features to work. For example, Windows 95
supports the power-management features upon detecting that APM is enabled in the
BIOS.
