I don't see where he states whether he has 32 or 64-bit version, but if you choose Windows 7 x64, you don't get those
drivers in the link you provided.
Also Windows 7 will install the LAN
drivers for you. It did for me.
Also I just tried to install the Intel LAN drivers for my board and Windows gave me a "these don't apply to your system" message and quit the install. Also looking for LAN drivers for my board on Intel's website don't reveal any Windows 7 x64-bit drivers as well.
Anyway It's not an issue for me since the Microsoft supplied ones work without issue.
