Patch of AppleBCM5701Ethernet for ML, Mavericks.

[Alex009988]

Hello. I decided to create a new topic in order to check and compare how well will it work with the native driver.

Many users have problems with BCM57781. And even the BCM5722D(2.3.5) doesn't help for them. For me, BCM5722D works excellently, but I am also keenly interested to try the novelty out.

To fix this in BCM5722D.kext you must have wide experience in programming so as to study datasheets and to make necessary changes in code. Having patched the native driver, it should be easier.

 

As was previously started, I think patches are different a little. So I'm gonna write it for each card soon and suggest methods of patches. You know, modern Duet-bootloaders such as Clover, XPC, bareBoot can do patches. Also, we can patch info.plist of its drive if we do create a special kext.(Just as for AppleHDA, and AGMP, for instance). In short, I wanna gather all of necessary information to the one message.

I hope it will work well.

 

Patches

This messages will be always updated after we come to know the exact particulars of it.

The patching method I described in http://www.insanelymac.com/forum/topic/292117-broadcom-bcm57781-how-do-i-patch-the-kext-for-ml-1085/ should work for all members of the BCM57785 family. The only thing you'll have to keep in mind is that you need to add the chip's name to the match list in Info.plist, for example "pci14e4,16b5" for the BCM57785.

Thank you very much. Look forward to try it out when I get home.

[Alex009988]

Unfortunately, for some reason, I couldn't find this stuff in my kext.

e8 89 ad ff ff

e8 6e ad ff ff

e8 65 ae ff ff

I attached the driver where I was trying to find it in.

What Do I do wrong?

Although the version number is still 3.6.9 you are using a newer build so that the instructions to patch have changed:

    706b:	ba 2c 00 00 00       	mov    $0x2c,%edx

Here what I've done.

Added this line to the plist

After I fixed permissoins and rebooted my laptop

At "Ethernet cards" I saw

This computer does not appear to have any PCI Ethernet cards installed.

It seems to be a famous mistake with getAdapterInfo.

Some information is written at this article, but unfortunately it's enoght old for my case.

Unfortunately, I still don't gain an understanding of what to change.

I would really apreciate it if you could give me a hint for it.

I also attached my patched driver.

Thanks in advance!

[Mieze]

I will analyze your patched kext tonight when I have more time but the fact that you get that "unknown chip" error messages shows that you made a mistake while patching it. In case of success your NIC would be reported as BCM57765.

 

Mieze

 

Thank you for your answer, but unfortunately it still doesn't work for me.

Here what I've done.

 

3) device-id

from

This is wrong, it should be

b8 b4 16 00 00       	mov    $0x16b4,%eax

in order to fake a BCM57765 which is natively supported.

But it says that my card is unplugged every time even if I put it out and plug it up again.

When I had switched off my wifi in order to watch if the driver would transmit any pockets, I did make sure that it got totally stuck.

Zero packets.

I attached the kext with the correction of mistake.

I forgot to add.

The members of the BCM57785 family use an internal or external flash memory to load configuration data and firmware. According to the error message the content of this memory is not as expected by the driver. As the patch is confirmed to work for Asrock boards with the BCM57781(I received positive reports for ML and Mavericks beta.) I don't know if the problem is related to the different NIC or an inappropriate firmware in the flash memory. Which board do you use?

Good morning.

I have laptop.  Boards for each laptop are different. 

	Motherboard Properties:
Motherboard ID  	<DMI>
Motherboard Name  	Acer Aspire 8942G

I also attached IOReg with BCM5701Enet and report from AIDA. Maybe it will help.

Just for your information, some old AppleBCM5701Ethernet worked for me. But I refused from it as it often stopped and didn't work after sleep.

I can't find that kext to show you as it was on OSX86 but they changed their site and all of the links disappeared.

[bretticus]

Hi guys. I have an Asrock Z77 Extreme4 board, and I just updated from ML to Mavericks. Everything seems to be working except ethernet. I have the BCM57781, and the old kext does not seem to work anymore. I have searched extensively and found this thread as well as the previous. Consequently, I have attempted to patch the AppleBCM5701Ethernet.kext file as explained, but I still cannot see any devices listed in System Report. I did make sure to add the info to the Info.plist as well, so that shouldn't be the problem.

 

When I look at Console, I seem to be getting errors regarding "no compatible dependency" with com.apple.iokit.IOEthernetAVBController. I'm not sure exactly what this means.

 

Any help would be much appreciated. I have attached my current patch. It's version 3.6.9b9, I believe. I also opened it in disassembler, and the calls seem to be patched as described.

 

Thank you!

Thanks, it worked with my BCM57785, I only had to add the dev-id to the info.plist, although is 3.6.9b2 it works awesome

 

EDIT: Looks like the driver losses connection when doing heavy activity ( Wi-Fi tethering, torrent downloads, etc)

Also it should not work after sleep? I afraid it is almost impossible to solve. Did you try this driver if you want not to lost the connecting during the heavy traffic.

Well, it's a known weakness of Apple's Broadcom driver after wakeup. Even my 2011 iMac is affected. At least it recovers the connection after 5 seconds. I'm not sure if this is a hardware problem or related to the driver.

It seems that I've solved the problem, I manually configured the interface so I disabled AVB/EAV mode and selected the other parameters to 100baseTX and duplex, it solved the problem for me and after sleep it continued working fine, and I tested this on the internet connection of my university campus (100mbps upload and download)

 

Hope this helps, and thanks for the driver!
