I don't see this posted, so I'm making a HowTo.

Anyways, this for when you have Intel PRO/100 VE. When you go into System Preferences/Network and your Built-In Ethernet is not show/grayed out, this is the fix for you.

You are required to add a product ID AppleIntel8255x.kext, which is located here:
/System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleIntel8255x.kext/Contents/Info.plist

If you don't know how to get into the kext, right click it and choose "Show Package Contents."

Anyways, you will find the following line.


You will have to add the following bit to the end of that line.


In the end, it will look like this:


Save the .plist file (save it to the desktop with the name "Info.plist" and then drag it into the Contents folder for AppleIntel8255x.kext. It will ask for authentication, which you say yes to (must type password if you have one).

Open up Terminal and type in the following



Open Disk Utility and Repair Disk Permissions.

Reboot.

Completed! Open up System Preferences/Network and you should see your Built-In Ethernet

Here is a list of device ID's + ICH that will work:

If you have ICH8 or later controller, you're probably out of luck for this fix.

If you add your device ID to 8255x kext, you will have to remove or rename AppleIntel8254XEthernet.kext

I have searched these forums and Goolge for some time now with out a resolution to enable the Intel 82562V-2 NIC.

Intel 82562V-2 10/100 NIC
Vendor: 8086
Device: 10C0

This hardware is on a Dell Inspirion 530 (Desktop).

I have tried the Intel Pro/100 VE - Read this

Also my Device ID Is listed here but the controller is a 8256x instead of 8255x. Also I have ICH9 which this states at the bottom will probably not work.
Has any one else had luck getting this network adapter working?

I have a Dell Vostro 200 which has the same NIC onboard (does that make it just a NI?) and can't make it work, either. If anyone out there has found a way, PLEASE let us know!
