Dood what steps did you take to get this to work? I'm a noob and have been searching for weeks and tried lots of suggestions but nothing has worked.
Either of the following works for me.
A. Copy RealtekR1000SL.kext into /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/;
RealtekR1000SL.kext
In Terminal do the following;
[mac05:~] me% sudo -s
Password:
[mac05:~] root# cp -r ~/Downloads/mac05/Bit\ Shoveler/RealtekR1000SL.kext /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/
[mac05:~] root# kextcache -v 1 -t -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions/
[mac05:~] root#
or
B. Copy /System/Library/Extensions/IONetworkingFamily.kext to ~/Documents/Extra/kext/.
Copy /System/Library/Extensions/IOPCIFamily.kext to ~/Documents/Extra/kext/.
Copy RealtekR1000SL.kext into ~/Documents/Extra/kext/.
Change <string>Network-Root</string> to <string>Root</string> in ~/Documents/Extra/kext/RealtekR1000SL.kext/Contents/Info.plist.
Change <string>Network-Root</string> to <string>Root</string> in ~/Documents/Extra/kext/IONetworkingFamily.kext/Contents/Info.plist.
In Terminal run kextcache and copy the new Extensions.mkext to your bootloader's Extra folder;
[mac05:~] me% sudo -s
Password:
[mac05:~] root# kextcache -v 1 -t -l -m ~/Documents/Extra/Extensions.mkext ~/Documents/Extra/kext
[mac05:~] root# cp ~/Documents/Extra/Extensions.mkext /Volumes/Boot\ OSX/Extra/
[mac05:~] root#
