HELP ME! BCM5754

[tatsumasadf]

I have a dell Precision T3400 everything except the Network card works.

It is a Broadcom NetXtreme Intergrated Gigabit Ethernet Controller BCM5754

the DEV_ID = 167A, VEN_ID = 14E4

 

I have changed /System/Library/Extensions/IONetworkingFamily/Contents/Plugins/AppleBCM5701Ethernet.kext/Contents/Info.plist to include my Card

 

and changed the hex code of /System/Library/Extensions/IONetworkingFamily/Contents/Plugins/AppleBCM5701Ethernet.kext/Contents/MacOS/AppleBCM5701Ethernet I found and replaced all 66 81 fa 59 16 to 66 81 fa 7a 16

and found and replaced 75 71 to eb 71

 

then opened terninal

   sudo -s
  cd /
  cd /System/Library/Extensions/
  ln -s IONetworkingFamily.kext com.apple.iokit.IONetworkingFamily.kext
  rm /System/Library/Extensions.kextcache
  rm /System/Library/Extensions.mkext
  chown -R root:wheel /System/Library/Extensions
  kextcache -k /System/Library/Extensions
  reboot

 

the when I was back to the desktop I opened terminal again and typed

	 sudo ifconfig en0 ether 00:1E:C9:41:64:C7

 

and got this back

 

   sudo ifconfig en0 ether 00:1E:C9:41:64:C7
  Password:
  \ifconfig: interface en0 does not exist

 

although the ethernet port shows up in the network settings it doesn't connect.

 

please someone help me fix this problem.

Well this isnt exactly a help with your current network card but why not go buy a cheap osx86 compatible card and throw that in... then you would have a 100% working machine! Network cards are cheap these days and it will save you quite a lot of headache

the DEV_ID = 167A, VEN_ID = 14E4

 

Just followed your directions (as I have the exact same VEN_ID and DEV_ID) with the same results... Although I can answer why en0 didn't exist. It looks like it came up as en2 with all zeros as the mac address and attempts to apply a mac address result with an error about the interface not being active. The network preferences never lets me in either.

 

My testing is with iATKOS v7 on an Optiplex 745 modifying the optional kexts from the DVD install (customize).
