After getting things fixed on my HP hackintosh now I want to go a little wild ( as my nature is ). I want to know what the problem is that we can't have our broadcom wireless cards working in mac. I see it's being detected in PCI list. However I need little info about what the problem is and what are the possible ways of solving the issue.
I know we can rebrand those cards but I won't prefer this option because of two things: 1. The chances are pretty too high that the cards get bricked if you do it wrong. Newer broadcom cards can't be rebranded til the time I'm writing this post. (Specially the 43225 card I have. ) Doing some research I found out that the broadcom has open-source drivers for linux so we can possibly port those drivers to mac. I haven't developed any drivers for mac yet but I'm an experienced C/C/ASM developer so I think i can figure it out.
I need you guys to write in every info you have on this cards and possible problems that make this cards not working in mac. There has been some success porting Realtek Ethernet (RTL8169) Linux drivers to OSX. To this point, there is no known success porting Broadcom BCM432xx Linux drivers to OS X.
The exact problem rebranding solved in older cards remains in the newer cards; the subsystem-vendor-id must be 6B10. In decompiling, the AirportBrcm4331 binary there are numerous checks for 6B10. Attached are IOReg/ARPT for a macbookpro6,2 with a BCM43225 and a P8Z77-I Deluxe with a half mini BCM43225. The only difference is the subsystem-vendor-id and subsystem-id. Two choices, 1.

Two choices, 1. Inject 6B10 or defeat 6B10 verification. I have tried to defeat the checks and I almost spotted 30 checks in the executable of the kext. I tried to change all the tests with an op that is always correct ( cmp ebx, ebx ). But it didn't work out. I have also tried to change the JUMP ops to NOPs.
And it didn't work out too. Do you guys have any idea about how to defeat the checks? When I run kextstat I see it is loaded.
It load with the untouched file too. Xap caching on safari for mac. Im confused:/ I use Hopper Disassembler to disassemble the file and assemble it back again. I have attached the untouched file, the patched file, and the Hopper Disassembler file. Please let me know if you got any idea. Consistent with prior findings.
A few suggestions: 1. Can particular values in a table be modified with a valid value? Two comments from the disassembler: a. Setting property susbsystem-vendor-id to%n n set to 0x106b instead of the value read from the firmware b. Setting property susbsystem-id to%n n set to 0x0093 instead of the value read from the firmware 2. Is there a tool that can read the firmware and modify the two parameters and reflash in OS X? Broadcom has updated its open source Linux drivers; brcmsmac is running on my BCM43224 in Ubuntu 12.04, see.
Is there a way to patch the brcmsmac firmware in Linux? The values that need to be edited a. $ cat /sys/devices/pci00:00:1c.6/0000:03:00.0/subsystemvendor 0x103c echo 0x106b sys/devices/pci00:00:1c.6/0000:03:00.0/subsystemvendor b.
$ cat /sys/devices/pci00:00:1c.6/0000:03:00.0/subsystemdevice 0x1509 echo 0x0093 /sys/devices/pci00:00:1c.6/0000:03:00.0/subsystemdevice echo returns a permissions problem. Fwcutter only works on the b43 drivers. 2 days I've been working on a script to convert the text ASM generated by any disassembler like Hopper (my choice), otx, otool, gdb, etc. To a reassemble-able file which you can assemble with AS, NASM. This is the outcome by now. I ask you guys if anyone can help on this script or the re-assemble thing feel free to contact me or post here. We need help on this.
Because as I already mentioned the Hopper assembling instructions option doesn't work well and causes parts of the code to be overwritten. So we need to find another way to re-assemble the disassembled file.
We're not too away from unlocking Airport for any Broadcom card.

Can anyone give a detailed description point-by-point what he did to get this thing working on an Asus PX? I followed what jokerdino suggested, except I added brcmsmac to rc. Double click on the package to install or in a Terminal issue the following commands: Thanks for saving my time, kalwisti. Once all of the required information is present, if the version of the driver you are using is the latest version available from the Ubuntu repositories, then one would want to e-mail the bdev mailing list following this procedure.

How to install Broadcom Corporation BCM b/g/n Wireless LAN Controller? Back to top b43 – No Internet access If you do not have any other means of Internet access from Ubuntu, then you will have to download the firmware from another computer with Internet access, from an existing OS on another partition, or before you install Ubuntu. The relevant driver has built-in logic to probe the actual chip, for example: Our home network can be seen by the computer, but it refuses to log on. I read all the above, which was very educating, and then I tried to follow the broadcom readme file instructions at: I’m trying to install a wifi driver on a Gateway NV56R14u.
Most likely I messed something up while trying to follow directions from all the stuff I read online, but they assume the user is not a newbie, and I am still one. When satisfied, the relevant Broadcom proprietary driver will be acquired, the firmware within will be extracted and installed. SOLVED broadcom BCM bgn 14e rev 01 on Slackware Post as a guest Name. Copy the downloaded file to your home folder.

To find out your current kernel use the command: If so, this may be helpful: If that is the case, you need to follow the Debian Wiki’s instructions for installing the “brcm” driver: Just add ” contrib non-free” to the end of your existing line. If your chipset is supported as per above, but doesn’t work, please file a bug following the b43 driver procedure below. The broadcom-sta package aims to offer an earlier version for a given release.

They won’t need to reverse engineer the Linux driver at all, seeing as the source is available. All they will need to do is re-implement the functionality using the Linux driver source as an example.
Its highly dependent on what licence the code is under. If they are not satisfied, then they’ll re-write their version based finding how the Linux works. (and re-release under BSD license and clean up the code).
This is what they’ve done with the Ralink RT2500 series chipset. Since this Broadcom reversed engineered driver is under GPL, expect another year (or two) until BSDs get a stable driver under BSD license. Its a bit late for me, as I use a pair of WRT54G routers with a third-party firmware to fulfill my wireless requirements.
I wanted to ask a newbie question here. Please, don’t flame me. I have an Acer laptop with a wireless card. Lspci lists the following information for it: 00:0b.0 Network controller: Broadcom Corporation BCM4318 AirForce One 54g 802.11g Wireless LAN Controller (rev 02) Is this driver supposed to work with this card? The original webpage mentions that their intention was to reverse-engineer the Broadcom 4301 chipset only.
The specs page mentions several PCI and CardBus cards, but mine doesn’t have a known brand that I can check against that list. And finally, the driver page mentions BCM 43xx (that would include BCM 4318, I suppose). Is this a targetted card? Apart from that, while ndiswrapper seems to work fine with the card, I would be very glad if I had a native Linux driver. Specially because ndiswrapper is a hack (a good one, though, kudos to the ndiswrapper people) and I’m not sure how long the hack will remain functional.
Kudos too for the people who reverse-engineered the chipset. I did not mean to imply that companies should give their IP away for free. I understand the resources invested in developing a product – although not specifically in wireless cards. Any my response presumed that Broadcom did not see the ROI in developing Linux drivers – hence my suggestion to release sufficient specs to enable third part development. The resultant drivers could be a cheap, easy way for Broadcom to get a feel for demand and size up the market opportunity, while precluding support investment. After all, they could always claim “Not our drivers – you’re on your own.” I still see this as shortsightedness – especially in a crowded, cut-throat margin business. There is everything to gain and nothing to lose by supporting Linux long term.

That’s my unbiased view, whether you accept it or not. Broadcom sells chips. The open source geek isn’t their customer. The company that buys chips by the pallet are their customers (minimum for one company was lots of a thousand). Open drivers aren’t going to do them any good. The companies that buy the chips might, but we’re yelling at Broadcom instead of the companies that make something with those chips, now aren’t we? “There is everything to gain and nothing to lose by supporting Linux long term.” Debatable, but anyway there’s more to the world than just “numbers”.
