Intel 82579LM Linux Driver under Ubuntu Lucid

I got a HP Compaq 8200 PC today, which has a i7 CPU with 16GB DDR3 RAM. After Ubuntu 10.04 64bit is installed, no network connection is found. Note: To get into BIOS, press F10 immediately after reset.

It turns out Ubuntu 10.04 Lucid does not support the Intel 82579LM PCIe Ethernet adapter.

Let's first find the driver source code from Intel:
http://downloadmirror.intel.com/15817/eng/README.txt
http://support.intel.com/support/go/network/adapter/home.htm (search 82579 in this page)
Another way to get the Linux driver from Intel's site is via searching keyword:
Intel® 82579 Gigabit Ethernet Controller
Note: You may get a newer version than the one mentioned below.

The driver code is not in Linux kernel yet.

Time to build it:
You can use USB stick to move the code to HP Compaq 8200 as there is no network yet.

tar zxf e1000e-1.11.3.tar.gz
cd e1000e-1.11.3/src
sudo make install

The driver is installed to /lib/modules//kernel/drivers/net/e1000e/e1000e.ko

It's ready to use:

sudo modprobe e1000e
sudo ifconfig eth0 up
sudo dhclient eth0
ping intel.com

Note: Whenever the kernel version is upgraded you will need rebuild this driver.
