edit: making a new thread because i need help with the audio also

 

I have the Intel PRO VE 100 network adapter, i have done some searching to see if i could fix my problem, and i found this

 

1) Start Terminal

2) sudo -s

3) cd /system/library/extensions/ionetworkingfamily.kext/contents/plugins

4) nano appleintel8255x.kext/contents/info.plist

5) under <key>iopcimatch</key> add <string>0x10518086 0x27dc8086</string>

6) kextload appleintel8255x.kext

7) rm /system/library/extensions.kextcache

8) kextcache -k /system/library/extensions

9) reboot

 

I followed it, but instead of using 0x10518086 i used 0x10928086 because it applies to my network adapter (dev and ven id). However, once i get to step 6 it says "cannot load appleintel8255x.kext use kextload -t for more information" (or something similar, dont remember what it says exactly) Then a message will pop up that says "You need to restart your computer". I restarted and opened the info.plist file, it remained edited...but because of what happened before did it not rebuild correctly? I tried it again and the same thing happened.

 

edit: sorry, i forgot i am using OSX86 v 10.4.6

 

and not sure if it helps but.. when using system info it lists en0 as my network adapter.

5) under <key>iopcimatch</key> add <string>0x10518086 0x27dc8086</string>

 

When you went to edit the file, there should have already been a <string></string> that contains a bunch of device/vendor id combinations. You should have just added 0x10928086 to that string. If you added another <string></string> line containing <string>0x10928086 0x27dc8086</string> then that would mess things up.

Ok, i changed that...but now when i try step 6 it says that it cannot complete the task because appleintel8255x.kext is invalid and i need to reinstall. It also says that i don't have sufficient access to modify the file..but i am logged in as the administrator.

You have otherwise corrupted the kext with your editing - it could be formating or a stray character or something else.

 

You will need to reinstall the IONetworkingFamily.kext

 

Download Pacifist from Charlessoft.

 

While in OSX, insert your install DVD and let it mount on the Desktop.

 

Run Pacifist, select File menu -> Open and path to the following: (Install DVD)/System/Installation/Packages/10.4.6 Update.pkg (If you can't find the 10.4.6 Update, then use the Essentials.pkg)

 

In Pacifist, click the little arrows beside the following: System -> Library -> Extensions

 

Find and select the IONetworkingFamily.kext and then select the Install button at the top of the window. Give your password.

 

Close everything up and (carefully) try your edit again.

I rebooted, and it didn't work, then i re-read the guide and it said to add two strings, so i added the second one (0x26dc8086) My info.plist file looked like this

After i did this, and restarted it gave me the error again, telling me the AppleIntel8255x.kext was invalid and i would have to reinstall it. I made sure that i didn't type any extra characters

 

Also, after the first edit of the info.plist i tried step #6 again, and it said that it could not rebuild...i forget exactly why

OK, ill boot into osx and try that, thanks. I am also having a problem with my audio and i don't see any threads with related information, my laptop is a toshiba r25 and the audio chipset is Realtek ALC262. Maybe you will be able to help me with that also :/

I was messing around trying to get it to work, i eneded up re-replacing the .kext file and re-editing it using different installation advice, however when i ran

sudo kextload /system/library/extensions/IONetworkingFamily.kext/contents/plugins/appleintel8255x.kext

i got this message

 

kevin-bs-computer:~ kevinb$ sudo kextload /System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/AppleIntel8255x.kext
