1-20 Technical Information
When Power Management is enabled, the computer automatically activates power-saving fea-
tures and enters a suspend mode whenever inactivity is sensed. The computer's power-saving
functions shuts down all installed devices, video signals to the monitor, and processor.
PLUG AND PLAY
The system comes with Plug and Play system support installed, and requires only the Plug and
Play operating system. When the Plug and Play operating system is installed, the system will
automatically configure newly added Plug and Play boards.
Plug and Play boards are ISA boards with the new configuration capability. Most currently avail-
able ISA boards do not have the new capability. However, Plug and Play boards can be added
to the system.
To work in a system, boards often use a variety of dedicated resources. If two boards try to use
the same resource, one board might not work or the system might not function in the way you ex-
pect.
NOTE:
Generally, a resource can be used by only
one board or device. However, some boards can
share the same DMA or IRQ resources. The board
manufacturer's documentation tells you whether a
board supports shared resources.
If an ISA board does not support shared resources and a Plug and Play board is not aware that
the ISA board is using the same resource it has selected, an ISA Configuration Utility (ICU) is
need. The ICU is used to eliminate the guess work from the configuration procedure. Although
most Plug and Play boards come with an ICU, an ICU can be obtained from the NEC Bulletin
Board Service (see Section 4, Troubleshooting and Maintenance).
Plug and Play boards are dynamic in nature — the system allocates resources to these boards
upon system boot. Some device drivers support this dynamic board configuration, but some do
not.
Device drivers that do not support the dynamic board configuration are also known as static
device drivers. If you are using a static device driver, you need to permanently associate
resources with a Plug and Play board, instead of relying on the default Plug and Play behavior.
Otherwise, the device driver might not be able to find the board the next time the system boots.
DESKTOP MANAGEMENT INTERFACE
The Desktop Management Interface (DMI) is a new standard for managing computer systems.
DMI is an interface between management applications and managed components such as sys-
tems, network boards, and printers used with or without networked computers.
