System Driver, Huh?

Anyone know what this could be? I have the following hardware:

Asus P5ND2 SLI Deluxe Mainboard (Latest BIOS)
3.6GHz Intel Pentium 4 (64-Bit Architecture)
160GB Seagate IDE HDD
DVDRW (via SATA)
ATI Radeon 3850 PCI-e 16x

Using Windows XP Pro + SP3, Catalyst Display Drivers, I can't seem to find any chipset drivers for this mainboard, so I have installed the Intel LAN Drivers, Realtek AC'97 HD Audio Drivers, But it shows this in my Hardware Settings, Can't work it out, Also the weird thing is it has installed a Sound Driver for my ATI Videocard, I had to manually go into my system sound settings and change it to the On-Board sound!

 

I downloaded the Nforce 4 AMD/Intel 16X Chipset Drivers from the nvidia.com file archive. now after an install of that package, my Pioneer SATA DVDRW is detected as a removable Device, what the heck, and it didn't fix the PCI listing, also are you meant to have multiple versions of this....

 

found the chipset drivers on asus' global support site, it's listed under utilities for that motherboard.
It won't let me put a direct link. http://support.asus.com/
