Plug & Play O/S yes or no

Whats the best setting of the plug & play in the bios. Is it better to allow bios or windows creat the settings?

If you are using Windows XP, the answer is set to yes.

Thanks for the quick response. It would be helpfull if someone can clarify why its better to let XP operate the P&P.

the plug and play setting in the bios is overwritten and superceded by Windows XP all the time that the computer is in use, even if you set the BIOS to yes or no. Windows XP manages the addressing of installed and added compinents often sharing IRQ addresses as there are actually not enough on some computers to spread 1-15 with cascading 2-9 and therefor not for components, and only 7 DMA addresses. then there comes ACPI

Thanks for the info uisquebeathus.
I get the basics now.

Set the Bios to No for Plug 'n Play.

...for XP.

I thought this was clear cut until Stuartli says 'no'.

Why no ?

Every system I've ever set up, (and that's a fair number - in the low hudreds), I've set Plug&Play OS to Yes.

Works for me!

This is what MS say click here

Die Sse
That hit the nail on the head.
Maybe a good idea if this info was better known. In my previous builds I always set to yes without knowing why. I am sure there are many others out there doing the same as I did.

I used to set it to Yes in XP Pro until the younger offspring, an IT support specialist whose forgotten more than most people know about all aspects of computers, very firmly informed me some time ago to leave it at No....:-)
