BIOS Setup PnP OS Setting XP?

Several years ago when I last paid any attention to the issue for W98[SE]
the correct setting in mobo BIOS setup for PnP OS was YES. If one reads the
description in BIOS setup then it suggests that yes is the correct answer
when one is booting a PnP OS.

Win98[SE] is a PNP OS as is XP and W2K3. YET I have recently seen
repeatedly posts that say set the PnP OS BIOS setting to NO for XP. Does
anyone know the correct answer here and what the apparent discrepancy is?
 
I have PNP on Yes. No probs with it. I think if its off, its
so you can set different IRQ's for some stubborn devices. Or if you
get frequent IRQ conflicts.

That may not work if PNP is enabled.

That's what I thought but I keep seeing apparent experts saying to set it no
for XP??

if you set it to off windows will assign IRQ to devices and there will be no
conflict, but if there is conflict when windows assigns IRQ its best to set
it to yes in bios, so that bios can assign IRQ adress!
for example: display cards with video-in function have conflict when
installing the capture driver which is needed to run video-in as you know!
when pnp is off in bios and some solve the problem when they turn on pnp in
bios and some don't!
is saw that it depends on motherboards! but thats example, and if you have
conflict on devices you should turn function in bios on on if it is off and
try installing device if it works live it like that! windows system are
buged and some times they assign same IRQ, but boards aren't buged some much
like windows!

In fact it is the other way around. Set it to "no" and BIOS will set devices
up. Set it to yes, and BIOS will only set up those critical devices needed
before Windows takes over and initializes other devices.

If you have an ACPI bios and OS it doesn't matter.

I don't know how Linux and ACPI play together. The article I linked to was
from
MS and as for as their concerned there is no Linux.

You have it backwards, you want it off to force the bios to set IRQ's

You want it on to allow a PNP aware os like 98/ME to have more control on the
process.

XP just ignore the setting period and controlls the IRQ's regardless of how it
is set.

And the article doesn't list that it applies to WinXP Home Ed.
either. ;-)
