One popular post on my site is about the Windows XP drivers for Dell Vostro 260. There is a new model: Vostro 470. I do not have this machine, but here are the drivers for Windows XP based upon the spec. Please let me know if they do not work for you.
Realtek PCIe GBE Network Adapter
Realtek Audio ALC887
Chipset and Video
Intel Driver Update Utility
The link to the chipset and video drivers is a utility that you can run under your browser window. You need to have Java installed to use it.
