Brothers I need some information. Is that true that a new imacs (i5 and i7) uses by default the bcm5764 Ethernet controller? And if it's so, why is my controller doesn't detected by system? That is what dmesg told me:

AppleBCM5701Ethernet: 0 d9 BJP firmware wakeup code unknown
AppleBCM5701Ethernet: 0 67020a02 InitNVRam - found non-5701 with serial eeprom or unbuffered flash
AppleBCM5701Ethernet: 0 0 getAdapterInfo - init/sanity check of nvram failed
AppleBCM5701Ethernet: 0 0 start - getAdapterInfo failed, giving up

As can I see, controller doesn't pass some test, but first of all its failed at nvram check. Is any one of you can say me how to disable nvram check in the driver. I know there are solution for 10.5 driver to disable nvram check, but in 10.6.2 absolutely different code, so I can not do it without your help.


hello, the driver isn't so much different in snow leopard, functions are about the same,i have seen too that now they dropped support for some old chips and added the 5764, i have already patched the nvram init and check, but without nvram you can't have the card working properly because of the lack of some vital informations. Using the hexedited driver i can get my 5764M working 50% of the times, the other 50% i get a panic as the driver load. i was trying to add the missing infos writing asm code directly into the driver, but this is not easy at all.
I don't know why the 5764m fail the nvram check, maybe the apple one has a proprietary nvram, or different in size.

Hi nobb1x! It's so good that here is some one who has same problems as me. As I can see you are more powerful in driver's editing, so can I ask you send me your modified driver for bcm5764? I will test it and report about errors. Maybe we will find decision together.

i got the 5761e, and i get the same error for nvram. what else did you edit to skip nvram checks? thanks

the 5764 is now officially included in the Apple driver, 5761 is not, there are hardware checks inside the code...
this snap is from GetAdapterInfo, and there are many others.

Youve probably already checked, but are you getting link when you plug in your cable? Have you tried using another piece of cat5? Based on your troubleshooting thats where I would look first.

I just want to share install boardcom 57xx dell latitude D820.
Details:
1)i am using iATKOS-v7 - it is 10.5.7
2) from windows xp, netcard is Boradcom 14E4 & DEV1600 and the netcard net address can be found from windows command ipconfig /all
3)others sound:sigmatel stac 92xx hd audio, vga:nvidia quadro nvs 120m
4)during installation:not choose any VGA, but choose chamelon V2,kernel 9.7.0, network card choose Broardcom 5751(not 5787), choose sound default voodoo hd driver
5) result: keyboard and mouse are not working and network en0 is never shown up) i am using external keyboard and mouse and they working fine. Sound is working good but VGA not perfect, sometime vga not smooth.
6) Big problem is broadcom 57xx
7)change all below addresses to 66 81 FA 00 16

<string>pci14e4,1600</string>
</array
8) copy it to MAC desktop
9) go to /System;/Library/Extensions/ , than remove applebcm5751.kext and replaced by new one
10) go to /System/Library/Extensions/IONetworkingFamily.kext,
then right click IONetworkingFamily.kext, shown package content, then to cotents and to plugins.
After that, remove applebcm5751.kext and replaced by new one.
11) from terminal do the followings steps
a)sudo -s
b)cd /System/Library/Extensions/
c)ln -s IONetworkingFamily.kext com.apple.iokit.IONetworkingFamily.kext
d)rm /System/Library/Extensions.kextcache (--no such file, don't know what happen)
e)rm /System/Library/Extensions.mkext

12) from terminal
a)ifconfig - enter
You will have en0 MAC address of 00:00:00:00:00:00
a)sudo -s
b)ifconfig en0 up
c)ifconfig en0 ether (your lan card address which can found from step 2)
d)sudo ipconfig set en0 DHCP (-- capital DHCP)
After that, I can go to internet. Good but not perfect !!!
13) shutdown the computer and start it again.
you will get en0 MAC address of 00:00:00:00:00:00 again.
I am afraid you have run step 12 again if you want to connect to internet
14)To conclude: what a good experience play with Apple!! Thanks to all they share their experience too.

swap the intel card with a broadcom 4311 minipci express, so easy to find on ebay and cheap
and it works in airport mode (i did it, acer don't has any blacklist on the bios, it don't affect warranty and it works with windows too)

why you don't switch to snow leopard? i think nobody will make a driver today for leopard 10.5.x
i did some hexediting to the snow leopard one and it works 50% of times (5764M only) in 32bit mode, of course it don't
work on leopard. i tried to hexedit the 64bit code too but it seem too much hard for me. i'm glad to let you try but
you need snow leopard.
My situation is opposite as yours, i use wireless network 100% of the times, but i did that just for fun.

Hi all, new to macs but fairly proficient programmer.

I have a broadcom 5754 with VEN_14e4 DEV_167a integrated with Dell Precition 390.

I have everyting working with iATKOS v7 10.5.7 except for my nic stated above.

I have tried just about every kext file and mod found in this thread but the best result i have gotten was the card be recognised by ifconfig but no connection possible via DHCP or Manual config. Although the mac networking preferences module says its connectd. Any attempt to change the MAC address using ifconfig i get "network down".

The last one i tried was with the 5787 dirver install as suggested below. Tried this on a clean install but this immidiatly locks up system after kext install.

I have the 5754 card also (device ID of 167a also) but modifying the 5751 kext as above did not work. Well, it worked, but I could not get a DHCP address or net with a static address because of the MAC address being all 0's (this is environment based, as some network routers, etc, will not communicate with devices that have 0 MAC addresses).

So, I modified the 5787 en0 kext in the same way crazy drummer did it to the other one, and got it working, since it then had at least some MAC address.

I just replaced the device id's of 1693 and 1698 to say 167a, in "AppleBCM5787Ethernet.kext" with Plist Editor (turns out nothing is needed to be done inside IONetworkingFamily.kext when the 5787 kext is used).

Then I changed the hex of AppleBCM5787Ethernet.kext/Content/MacOs/AppleBCM5787Ethernet with Find and replace all of "66 81 FA 93 16" with "66 81 FA 7A 16",
then "F8 08 75 59" with "F8 08 74 59"

then "install the 2 kexts, then the usual repair permissions/clear cache/rebuild cache/touch extensions folder housekeeping stuff " :)

ended up with a nonsense MAC of ba:ad:f0:0d:ba:ad that I believe the 5787 kext defaults to, but whatever, it's better than all 0's and going through the process of more hex editing (i didn't know the mac address of the NIC to begin with haha)

but worked like a charm! Couldn't have done it without crazy drummer's and everyone's persistent hacking!

So thanks a ton, and I might as well attach the modified kexts in case someone else has a BCM5754 Broadcom NetXtreme 5754 with device id 167a from an HP 5850. (for the googlers) ;)

Peace all, and Good Luck!



So now i am just about done with this untill any body has a modified kext that they think will work on my system. I know most have moved onto snow leppord but its just not worth the upgrade time for me as there is now way to install snow with out first doing 10.5.x install first. correct me if i am wrong.

Thanks to Loepere's previous post, I was able to get the Broadcom BCM 5755M (device id 1673) working flawlessly on my Dell Latitude D830 running Leopard 10.5.4 (no more GSOD or "freezing" after limited use).

I used EternalEmpty's AppleBCM5751Ethernet.kext (downloaded BCM57XX.zip from http://forum.insanel...o...114605&st=0). I followed the directions in the tutuorial.

I then changed the entry in /System/Library/Extensions/AppleBCM5751Ethernet.kext/Contents/Info.plist:

pci14e4,167d to pci14e4,1673 (my device id)

Then I copied /System/Library/Extensions/AppleBCM5751Ethernet.kext/Contents/MacOS/AppleBCM5751Ethernet to my home folder so I could edit it with Hexedit, and replaced all occurrences:
"66 81 FA 7D 16" with "66 81 FA 73 16"
to match my device id.
Note: I did not change address 37554, 37555 of "75 71" to "EB 71" to bypass the call to InitNVRam - I left it as it should be ("75 71").

And now here is the elusive solution...

I located the section BCM5751Enet::getAdapterInfo and found the identical code which Loepere refers to. I changed "jne L1" into a "je L1" which using Hexedit simply translates to:
address 376C0: replace "F8 08 75 59" with "F8 08 74 59"


Copied the modified AppleBCM5751Ethernet back to the original location in /System/Library/Extensions/AppleBCM5751Ethernet.kext/Contents/MacOS.

MAC address gets assigned correctly to en0, and DHCP works perfectly.


Running iATKOS v7 10.5.7 on DELL Precition 390

UPDATE: Aparently after a clean instal followed by the procees below it crash my system. However there is a fix.

Fifst install the kext in raybabas post above (no need for IONetworkingFamily update). Just modify the info.plist for your DEV_ID and install with kext helper, repair permissions then follow the instuctions below for my modified kext.

raybabaPosted Dec 26 2009, 12:21 AM


This worked perfect for me with a Broadcom 5754 DEV_167A !!!! But i can simplify the install process a bit as follows:

1) After you download BCM57XX.zip

2) Change entry pci14e4,167d to pci14e4,your device id here in both kext files:

/System/Library/Extensions/AppleBCM5751Ethernet.kext/Contents/Info.plist

/System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/AppleBCM5751Ethernet.kext/Contents/Info.plist

3)HexEdit:

/System/Library/Extensions/AppleBCM5751Ethernet.kext/Contents/MacOS/AppleBCM5751Ethernet

change "66 81 FA 7D 16" to "66 81 FA 7A 16" on all locations. Just substitute your the last two charicters of your device id for 7A.


4) After you make all your mods as described above just install them with KextHelper.

5)In diskutil repair permissions on your drive

6)Reboot with -f flag.

I have attached my modded kext files ONLY FOR Broadcom 5754 DEV_167A . For other DEV_ID you must follow the insturctions above.

Attached File  BCM5754_14e4_167a_working.zip   1.16MB   380 downloads


MODERATORS PLEASE MAKE THIS A STICKY!!!!!

I spent 2 days and tried every soluton in these 40 pages and noting worked except for this.

Correct MAC address, DHCP, connected and working 100%.

UPDATE: On load the system rocognises the MAC address but says it is taken by another controller and gives me all zeros. very strange. But DHCP does work without having to change MAC address.

Is there any way to hardcode the mac address in the BCM5715 kext for 14e4 1677?
When I try to set the mac address manually Leopard hangs, because of the nvram addressing problem.
I read in a BCM5787 thread that it's possible to enter the mac address with hexedit.

hello folks, as you may know latest I7 IMacs use a Broadcom 5764M as wired ethernet chip. This chip is now fully supported
by the AppleBCM5701Ethernet.kext but it seem the Apple one has a proprietary nvram so our pc chips fail the nvram check
and the kext won't load. Here is an hexedited version of the kext for you to try, it come from 10.6.2 and it works only on 32 bit mode. Attempting to start it in 64bit mode lead to nothing because the 64bit code is not patched, feel free to reverse my mods and apply it to the 64bit portion if you have a such disassembler.
What i did here is to bypass the nvram type check and to apply huge patches to the Init_NVRAM routine. Leopard versions of the hexedited kext had a wrong patch imho, disabling at all the init_nvram, causing lot of troubles, like impossibility to unload, no sleep, no mac address and impossibility to change it manually.
All of these functions are supported by this, at least on my laptop ;)
HOWTO:
make a backup and replace the System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/AppleBCM5701Ethernet.kext with this.
repair permission and reboot
Beware, don't use automatic installer because they install the kext on the S/L/E rather than in the Plugins folder of the IONetworkingFamilykext, you need to do it by hand.

to set your MacAddress (otherwise all 00) from the terminal: sudo ifconfig en0 (or en1) lladdr YO:UR:MA:CA:DD:RS

if it don't work work for you, you don't like or it crash your system, start with -s and remove it manually.

BEWARE NOOBS: this is only for SNOW LEOPARD and Broadcom 5764M chip, the code has many checks to read the chip ID, feel free to hack it and try on other BCM cards, a simple plist change won't do the job.

UPDATE: 64 bit mode too available!!!!
Attached File  32_64Bit_AppleBCM5701Ethernet.kext.zip   159.15KB   684 downloads

UPDATE: 10.6.3 version
Attached File  10.6.3_AppleBCM5701Ethernet.kext.zip   177.23KB   701 downloads

as far i know, it show a warning in the logs about unknown ACPI low power methods, but it support sleep, unload, and it read the mac address from the card. support for both 32 and 64 bit modes.
if the card don't get the address from the dhcp, set it manually.
To install replace the original kext into IONetworkingfamily.kext/Contents/Plugins, fix permissions and reboot.
