Identify procedures for loading/adding and configuring
application device drivers, and the necessary software for certain
devices.
Windows 9x Plug and Play and Windows 2000
Plug
and Play is an independent set of computer architecture
specifications that hardware manufacturers use to produce computer
devices that can be configured with no user intervention. When you
install a device, you do not need to know its Plug and Play
requirements, because they will be set automatically.
You
can install hot-pluggable Plug and Play–compliant devices simply by
plugging in the device. For other devices, such as Plug and Play
Industry Standard Architecture (ISA) cards, you must plug in or
install a device while the computer is off and then turn the
computer back on to initialize the device.
Windows 98 detects the presence of a Plug and Play–compliant device.
This is known as enumerating the device. After enumeration, the
device driver can be configured and then loaded dynamically,
requiring little or no user input. Certain buses (for example,
peripheral component interconnect [PCI] and Universal Serial Bus
[USB]) are also automatically enumerated; these buses take full
advantage of Plug and Play capability.
You
can add some Plug and Play functionality by adding Plug and
Play–compliant devices on legacy computers. Therefore, it is best to
add Plug and Play–compliant devices on legacy computers rather than
adding non–Plug and Play devices. To be able to use all Plug and
Play features, however, your system must also include one of the
following:
-
An Advanced Configuration and Power Interface (ACPI) BIOS.
-
A Plug and Play BIOS (for Plug and Play devices on the system
board).
-
The Plug and Play–compliant hardware devices (including buses).
