Right I've never really understood this 100% but I definitely need to get my head around it all. Can anyone explain this to me?

I've just done a clean install of XP and i know that now the chipset drivers off the motherboard CD need to be installed.

1) What the hell are chipset drivers and why do they need to be installed exactly?

on the cd that's come with my p4p800 deluxe motherboard the drivers are listed like this:

a) Intel Chipset Inf Update prog
b) Intel Application Accelerator Driver
c) Via Raid Driver
d) ad1985 Audio Driver
e) USB 2.0 Driver
f) 3 Com Gigabit LOM (3c940) Driver

2) What do a,b,c and e exactly???? I know USB 2 is for the usb 2 card and the audio driver is for the on board sound (which I'll leave off cause i have a soundcard) but what's the rest for and why do I need them?

3) Which ones do i need the most recent versions of and how do I get them for the p4p800 deluxe? does anyone know direct links to all this?

phew. sorry to ask all this but i really need to understand it so my computer runs good. i really don't want another 2 years of hell like on my last pc :cry:
