macosx86 Broadcom NetXtreme Gigabit Ethernet 網卡

關于這個問題，網上有文章讨論已經很多了，就是mac本身不識别的硬體裝置，都是用修改驅動使得系統和裝置ID确認就可以了，下面引述coolrain的文章中描述的方法：

＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

其實修改硬體驅動的方法都是差不多的，關鍵就是要在"/System/Library/Extensions/"目錄裡面找到對應的.kext檔案，然後進行修改。

現在已經有很多與你自己特定硬體（不管是聲霸卡、顯示卡、網卡、無線網卡等等，原理都一樣）的驅動，你所要修改的關鍵就是在這些.kext檔案中寫入你自己硬體的Device ID。

隻要Device ID寫對了，你再通過kextload xxxxxxxxxxx.kext指令來加載你改好的.kext驅動，如果正确的話，會現示load successfully的。

然後你就需要到"/System/Library/"目錄下清除一下kext 的cache，具體指令如下：

sudo rm /System/Library/Extensions.kextcache

kextcache -k /System/Library/Extensions

然後重新開機就可以了。

難點就兩個，第一，找到要修改的kext檔案。第二，正确的對kext檔案作修改，寫入你自己的Device ID。

以我在osx86project發的文章作示範吧，關于修改網卡的：

QUOTE:

At last! I get my "BroadCOM NetXtreme Gigabit Ethernet" interface card work!

I identify my device-id of BCM57x in windows, it is a "165E".

And then use the method below to get it work.

=================================

Run terminal

sudo -s

cd /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleBCM5701Ethernet.kext/Contents/MacOS

cp AppleBCM5701Ethernet /Users/your_account_name/Desktop

---

(back to Desktop)

1) right click AppleBCM5701Ethernet, Get Info.

2) change ownership & permissions as you can modify it.

3) run HexEdit, then open AppleBCM5701Ethernet

4) choose "Find & Replace" from menu.

5) Find: "66 81 FA 59 16" /Replace with: "66 81 FA 5E 16"

(my DEV_ID was 165E, you type yours at last two bytes)

6) Matching: "Hex: (<-choose this)

7) push "Replace All"

8) scroll down to 37550

9) change address 37554, 37555 of "75 71" to "EB 71"

10) then save file and quit Hex Edit.

11) change ownership & permissions as before (by Get Info)

ownership="root" and group="wheel"

12) (return to terminal)

===========================================

Hope this would help if you are using the simulier device like me.

其實大家大可不必這麼費勁，想省力的朋友象我一樣關機、出門、賣塊50大元的intel網卡（二手的一頓KFC的價格都夠）、回家、插進去、開機…
