@ AssKick:
This is what I did to have my Intel PRO/100 VE NIC working, be advised that is not guaranteed to work on your Hackintosh setup:
You're required to add your Product ID number to AppleIntel8255x.kext, which is located here:
/System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleIntel8255x.kext/Contents/Info.plist
Navigate your HD using Finder up to the folder Extensions, once you find IONetworkingFamily.kext, right-click on the file and select Show Package Contents from the context menu. Then navigate again in the new Finder window to Contents/PlugIns/AppleIntel8255x.kext and once again right-click on it, then Show Package Contents, navigate again to Contents and finally Info.plist inside it.
Open Info.plist with a double-click and scroll down until you find this:
QUOTE
<key>IOPCIMatch</key>
below it, you'll see:
QUOTE
<string>0x10928086 0x10518086 0x10508086 0x10298086 0x10308086&0xfff0ffff 0x12098086 0x12278086 0x12288086 0x12298086 0x24498086 0x24598086 0x245d8086 0x10918086 0x10608086&0xfff0ffff</string>
in my case, the product id string is 0x10928086 (1092 - Intel PRO/100 VE NIC, 8086 - Intel Manufacturer)
you can add yours to the begining of the list, as in my case, or to the end, just before "&" (without the quotes)
When done, save the Info.plist to your Desktop (you can't save it in its original location) and exit the text editor. Now drag the Info.plist from your Desktop to the Contents folder. It will ask for authentication and your user password, enter it and you're almost done.
Open up Utilities folder (Shift-⌘-U) and open Terminal and type in the following:
QUOTE
sudo rm /System/Library/Extensions.kextcache
and:
QUOTE
sudo kextcache -k /System/Library/Extensions
Open Disk Utility (again, inside Utilities folder) and Repair Disk Permissions for your drive, wait for it to finish and reboot.
Once rebooted, check in System Preferences, Network to see if it shows your ethernet card, some people have reported that up to this point some do work. If not, as in my case, do the following:
Open up Terminal again and type:
QUOTE
sudo -s
it will ask for your password, enter it and type the following:
QUOTE
nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
just below the Kernel Flags section add "-f" (without the quotes), you'll see something like this
QUOTE
<key>Kernel Flags</key>
<string>-f</string>
press ⌘+X,
then Y
then Enter
Reboot your computer, go to System Preferences, Network and you should see your Ethernet active.
If it happens that you see your network card but it says there is no ethernet cable plugged in, delete /System/Library/Extension.mkext and reboot your system and check again.
Good luck!
