I didn't create a new INF, my Windows knowledge is still very limited. You'll need to install them "by hand"... Download the nForce3 drivers from nVidia, then unpack them (but do not install them). Download the newer drivers from http://gigapeta.com/dl/58274a502e32 (I found those in a russian board; I assume whoever uploaded them got them from some unarchived nvidia release). Go to Device Manager, then update driver for "unknown device" "PCI Bridge"; select driver from list, select "have disk", point the "have disk" dialog to the "ethernet" folder in the unpacked nForce3 drivers. After rebooting, the device will have the yellow warning sign on device manager (not the right driver for it). Now go to Windows\System and replace nvenet.sys with the one available in the newer driver. Go to the registry editor, key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net\ And search for the "subfolder" whose DriverDesc is "NVIDIA nForce Networking Controller". You'll need to update the following keys: AdapterCFID DeviceCaps Ndi\DeviceID (it MIGHT work without updating them all, but never tried ) You can get correct values for your nForce version by looking at nvenet9x.inf in the newer drivers. For example, A8N-E is nForce 4 AMD (a.k.a. ck804, nvenet9, pci device id 0057), and the values are "AdapterCFID"="005710DE" "DeviceCaps"="005710DE00000002000000000001000200001F1F00FC00070024000100000000" Ndi\"DeviceID"="PCI\\VEN_10DE&DEV_0057" It should look like this: REGEDIT4 [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net\0002] "DriverDesc"="NVIDIA nForce Networking Controller" "DevLoader"="*ndis,*ntkern,*ndis" "DeviceVxDs"="nvenet.sys" "EnumPropPages"="netdi.dll,EnumPropPages" "AdapterCFID"="005710DE" "AdapterType"="5" "BusType"="5" "DeviceCaps"="005710DE00000002000000000001000200001F1F00FC00070024000100000000" "InfSection"="NVENET.NDI" "NTMPDriver"="nvenet.sys" "InfPath"="NVIDIA~2.INF" "ProviderName"="Nvidia" "DriverDate"=" 3-16-2004" "OemSetting1"="1" "ForceSpeedDpx"="0" "PollIntervalInus"="425" "MatchingDeviceId"="PCI\\VEN_10DE&DEV_01C3" "ASFEventBitmask"="0" [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net\0002\Ndi] "DeviceID"="PCI\\VEN_10DE&DEV_0057" "InstallInf"="" [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net\0002\Ndi\Interfaces] "Lower"="ethernet" "LowerRange"="ethernet" "Upper"="ndis3" "UpperRange"="ndis3" [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net\0002\Ndi\Install] "ndis3"="NVENET9x.INSTALL" [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Net\0002\Ndi\params] By installing only the newer drivers, vital entries (AFAIK) like DeviceVxDs or DevLoader would not appear at all.
