Plug and Play is the name of a technology that lets PC hardware and
attached devices worktogether automatically. A user can attach a
new device ("plug it in") and begin working ("begin playing").
This should be possible even while the computer is running,
without restarting it. Plug and Play technology is implemented
in hardware, in operating systems such as Microsoft(r) Windows(r) 95,
and in supporting software such as drivers and BIOS.
With Plug and Play technology, users can add new capabilities to
their PCs, such as sound or fax, without having to concern
themselves with technical details or encountering problems.
For users of mobile PCs (who are frequently changing their
configurations with docking stations, intermittent network
connections, etc.), Plug and Play technology helps manage their
changing hardware configuration. For all users, Plug and Play can
reduce the time wasted on technical problems and increase
productivity and user satisfaction with PCs.
There are a variety of Plug and Play technologies, including BIOS,
ISA, SCSI, IDE CD-ROM, LPT, COM, PCMCIA, and drivers. A series of
specifications are available for many of these. In a nutshell, each
hardware device must be able to be uniquely identified, it must state
the services it provides and the resources which it requires, it must
identify the driver which supports it, and finally it must allow
software to configure it.
As of January 1996, the Plug and Play information available on
ftp://ftp.microsoft.com:/developr/drg/plug-and-play contains
principally the Plug and Play specifications as self-extracting
zip files for download. For more up-to-date information about
Plug and Play, including information about ACPI Plug and Play,
see http://www.microsoft.com/hwdev/.
Hardware that receives the "Designed for Microsoft Windows" logo
must be tested by the Microsoft Windows Hardware Quality Labs (WHQL).
For up-to-date information about WHQL testing
and the "Designed for Microsoft Windows" logo,
see the following site on the World Wide Web:

The following list describes legacy Plug and Play information available
on ftp://ftp.microsoft.com:/developr/drg/plug-and-play.
The files in this section are zipped files in Microsoft Word for
Windows format. (The ".exe" extension indicates a self-extracting
zip file.)
