Pardon my ignorance but is Vista &/or XP a Plug & Play O/S.
I've always BIOS'd 'yes' just guessing. What would happen if I 'no'd'?

I never noticed any difference after installing Windows thousands of
times. I wouldn't worry about it.
 
Yes, vista and xp are P&P and on my ASUS A8V, the default was no in the
BIOS.

Here is what the A8V manual says about that BIOS option:

'Plug and Play O/S [No]

When set to [No], BIOS configures all the devices in the system. When set
to [Yes] and if you installed a Plug & Play operating system, the operating
system configures the Plug & Play devices not required for boot.

Configuration options: [No] [Yes]'

IMHO, choosing "yes" is possibly the better option because it avoids
the potential problem of both the BIOS and OS writing different data
to the ESCD table in NVRAM. For example, a PnP OS may configure the
PnP devices differently to the BIOS, in which case it will write its
preferred configuration to NVRAM. At the next cold boot the BIOS may
update the NVRAM with its own preferred configuration, and the OS will
then update it again, and so on. Your motherboard's flash EEPROM is
spec'ed to tolerate many thousands of writes, but IMHO it would not be
a good idea to allow this scenario to continue. Unlike USB flash
drives, there would probably be no wear leveling, and in any case the
ESCD table occupies a fixed position in the BIOS chip.

I have configured Device Manager to prevent Windows from updating
NVRAM, so I don't have this problem.

On most PCs I've looked at the BIOS setting says 'no', and they work
fine. Exactly what it controls i'm not sure, perhaps its to do the
whatnot table that laptops need to dock without a reboot - but I dont
know.
