Asus® P4P800S-X motherboard and Windows® 7.
I know there are no Windows® Vista or Windows® 7 drivers released by Asus® for the P4P800S-X motherboard. The actual computer had an Asus A9550 AGP video card installed so I will include that in this article. Windows® 7 did a good job of installing device drivers for most of the components. The only component that needed a new device driver was the audio system and I found that by searching the Internet. I also installed updated drivers for the Realtek RTL8139/810x ethernet NIC. I have installed every driver listed so I know they work under Windows® 7.

Some files may require that you set compatibility before the install. You only need to set compatibility on the acutal executable file (the install program to run).

Asus® CD\DVD burning software.
I did not actually install any CD\DVD software but I see no reason why any current software version would not work.

The Windows Experience Index is only 2.2 because of the graphics component. Aero is working but I did not do much testing.
