First find ethernet using:
```
lspci
```
mine is:
```
00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (Lewisville) (rev 04)
```
then:
```
lspci -s 00:19.0 -nnn
```
mine is:
```
00:19.0 Ethernet controller [0200]: Intel Corporation 82579LM Gigabit Network Connection (Lewisville) [8086:1502] (rev 04)
```
After that,
```
git clone git://git.ipxe.org/ipxe.git
```
copy general.h to ipxe/src/config/local/ ,
copy netboot.ipxe to ipxe/src/ and
then build the ipxe rom; in my case:
```
sudo make clean; sudo make -j3 bin/80861502.rom EMBED=./netboot.ipxe
```
after compile add the ipxe rom to your coreboot rom this way:
```
sudo cbfstool coreboot.rom add -f 80861502.rom -n pci8086.1502.rom -t raw
```
Flash the new coreboot rom and enjoy.
