That's what I said isn't it? The hardware manufacturer does not supply
any drivers because the drivers needed were shipped with the specified
OS. THAT is Plug 'n Play. It is the only way the manufacturer can be
sure you DEFINITELY have the drivers.



No that is not what you said.

An excerpt from a M$ webpage describing the ISA PnP specification v1....
(a little old, but the only one I could find there)

---------------------------------------------------
This specification presents a mechanism to provide automatic
configuration capability to Industry Standard Architecture (ISA) cards
thus enabling full Plug and Play in the PC. The essential elements of
Plug and Play ISA are:
?
Isolate the ISA card
?
Read the card's resource data
?
Identify the card and configure its resources
?
Locate a driver for the card

The mechanism has the flexibility to allow cards to come up either
inactive or active. Cards required to participate in the boot process
typically come up active. Information that identifies the card and
describes the system resources which are requested by the card, such as
memory and I/O space, DMA channel, and interrupt level supported is
maintained in a standard read-only format. This allows the Plug and Play
software to identify system resource usage, arbitrate conflicts, and,
optionally, re-configure a card. This process is done automatically at
every hard reset of the system. Plug and Play ISA cards will inter-
operate with standard ISA cards in a fully compatible manner.
----------------------------------------------------

This does not mean that M$ provided the drivers. It means that Windows
can automatically identify and assign resources for the device, which
also mean the resources can be changed through Windows. The last step of
the PnP operation is locating the drivers. IF, one is already there,
either supplied by M$ or by the hardware mfg, it will use that one. If
not, it will ask you to supply them.

Also, the only true way a hardware manufacturer can be sure you have the
drivers is to supply them to you with the hardware device you buy from
them.

On the other hand UPnP may be a little different, but I'm not up on that.
