Install Ethernet / Internet on mavericks 10.9.0 / 10.9.4 on AMD & ASUS

Understand this guideline is only for following machine specifications:
1. AMD processor (any)
2. ASUS motherboard (any)
3. Compatible Graphics card - (if not compatible with mavericks or unsure, remove graphics card from motherboard before you proceed - NOTE: All onboard graphics card are incompatible)

Assuming you're in Mavericks

Copy nForceLAN.kext [DOWNLOAD&UNZIP] and paste it in  System/ directory. you'll find System directory in root.

now reboot.
On reboot, boot your mac with following boot options:

mach_kernel_self -v -s -x UseKernelCache=No

in single user mode write :

sudo -s

fsck -fy

mount -uw /
 
sudo cp -Rp System/nForceLAN.kext System/Library/Extensions/
sudo chmod -R 755  System/Library/Extensions/nForceLAN.kext
sudo chown -R root:wheel System/Library/Extensions/nForceLAN.kext


After you have installed all kext files, finally rebuild kextcache.

sudo kextcache -m  System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext System/Library/Extensions

sudo touch System/Library/Extensions

This should be final command (it repairs permission on mavericks) before you reboot:

sudo /usr/libexec/repair_packages --repair --standard-pkgs

sudo shutdown -r now

If you reboot without kernel panic, you're done. if not, leave a comment.
