On a Shuttle SN95G5 V3, with an Nforce 3 250 chipset on a Shuttle motherboard model NF7 V3, device manager does not report a LAN adapter present immediately after installing Win 7 Beta. Installing the ethernet adapter driver only from a couple of packages of Nvidia Nforce drivers does not affect this, even when using Vista compatibility mode on driver software is used. Note: LAN adapter works fine using Vista. Thanks to a couple of people on the Shuttle forum, I have found and downloaded the right device driver for the LAN adapter on my mobo. However, it is not executable and must be installed from Device Manager, which does not report any network adapter.
