Osx x86 Intel/AMD - Broadcom BCM5752

In this approach I used the "ual808" post in http://forum.insanelymac.com/index.php?sho...4987&hl=hex

Using 10.4.5 (Broadcom BCM5752) dev id: 1600 Vendor Id:14e4

save the file /System/Library/Extensions/

IONetworkingFamily.kext

in the desktop
(in the desktop copy) right click and "show contents"
find the Contents/PlugIns/

AppleBCM5701Ethernet.kext

right click and "show contents"
you going to find a file named

AppleBCM5701Ethernet

(you are going to use the hexeditor on it) drop it in the desktop!!

you could download an hex editor in
http://www.versiontracker.com/dyn/moreinfo/macosx/10658
or
http://www.apple.com/downloads/macosx/deve...tools/0xed.html

in the hexeditor go to Find "66 81 FA

59

16

" and replace all matches with "66 81 FA

00

16

"
ps. my deviceId is

16

00

, took time to understand the changing smile.gif

scroll down to line 37550 and change.....
change address 37554, 37555 of "75 71" to "EB 71"

save and close the file....

than inside the

AppleBCM5701Ethernet.kext

you going to find the file named "

Info.plist

" open it and replace the entry <string>pci14E4,1659</string> with <string>pci14E4,1600</string> and save the file.

Put back the

AppleBCM5701Ethernet

inside the

AppleBCM5701Ethernet.kext

(same place).

drop the modified

IONetworkingFamily.kext

in the original location (should need root password)

then run the commands

sudo -s
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
shutdown -r now

then you will reboot.....
once booted, you need to setup the network

# setup the mac address (see it in windows "ïpconfig /all")

sudo ifconfig en0 ether 00:13:72:18:XX:YY

# start options

sudo ipconfig set en0 DHCP

By now you should ping your default gateway.
