This thread is for people what want to help develop the ipw2200BG (and compartible) driver. I don't think that Intel will publish an official driver for os x86, so it is to us to make this thing work. Why don't people with this Wireless Adapter problem and others willing to help finally organize and start a mini-project on coding this driver so it works? I am willing to help, but my level of x-coding, darwin and I/O is not sufficient to be productive from the beginning.
Please answer asap with your comments and whether such thing would be possible. This is a wide spread device. So I think that many people are interested in getting this finally working.
To all those, who can help: Please do. Hi guys, i'm running Tiger 10.4.3 on my Sony Vaio VGN-FS115S and i'm in trouble to make wireless and nvidia (GeForce 6200) work. I've tried the iw2200 driver from tuxx. I have this driver on my 'todo' list. Just very busy with school. Anyway, some pointers and hints.
Get the.BSD and Linux drivers (if you dislike GPL, skip the linux one, yuck!). Read the network kernel extension guide on apple.com/developer (It's rather short, and not very indepth imo). Read docs on IOKit. It's a c framework and VERY diffrent from.Bsd/linux drivers (workloops and such). apple80211 (/System/Library/Frameworks/Kernel.framework/Headers/IOKit/apple80211) is a 80211 stack for OSX, the library is.NOT.
Intel R Pro Wireless 2200bg Network Connection
included in 8f1111 (but it is included in 8f1039). It's also included in 10.4.4, and it loads correctly (don't know if it works. Might be an idea to look into if someone who has a Broadcom 'AirPort' (what chip?) card can see if the 10.4.4 drivers work on 10.4.3) This framework is acctually a c port of the BSD 80211 library (that the bsd drivers use, so it'll probably fit rather good) Also, there is tuxx's channel, #osx86.wireless, I usually hang out there. Edited January 20, 2006 by phb. People, As tuxx reported, that driver does nothing but load firmware and ucode onto the 2200bg chipset. It won't work yet as a 'real' wireless card.
It won't work as a network card whatsoever (except it is reported by ifconfig and the mac address is recognized ). I know C/C, so I want to start working on this. I got the 802.11, 802.11b and 802.11g standards specifications from IEEE (they provide them for free). I am currently looking at the OpenSolaris implementation (I find it has a bit more comments in sensible areas of the code) and with the specs I think I should be able to make sense of what is involved in creating a wireless driver for that card. I've contacted tuxx telling him about my willingness to help, and I'm waiting on a reply from him. Meanwhile, if you're not a programmer, or you're not willing to help coding, there's unfortunately not much you can do When a major breakthrough is made, you'll hear about it! Of course, if you want to help coding, I think you should contact tuxx.
OK, with the latest version of XCode, I got a Kernel.Framework which contains a 802.11 IOKit family. I'm attempting to build a driver (based on tuxx's), however I am running into a small (?) problem.
I load my kext, but it complains: 15AirPortIPW2200 is not compatible with its superclass, 17IO80211Controller superclass changed? Kextload: a link/load error occured for kernel extension IPW2200.kext kextload: clearing all version/dependency relationships among kernel extensions load failed for extension IPW2200.kext. Now, I'd like to ask other people with more Darwin/OS X driver development experience than me. What does this message exactly mean?
From what I can tell, the driver should be fairly straight forward. The IO80211Controller subclasses IOEthernetController and adds wireless extensions, such as getSSID, getRSSI, etc.
After getting the firmware to load and setting up packet flows, the wireless extensions should be fairly easy to implement. Also, the IO80211 header files seem to be missing some comments (a couple of??? Here and there), so I hope that Apple will release updated headers with more comments with the framework bundled in the next version of XCode. In another note, I got a reply from tuxx (I asked him if I could be of any help in developing these drivers). His reply was simply 'die.' I don't know what his reasons were, and I'm not going to start criticizing him, however, I have one piece of advice for him: You said you want help with this, yet when help comes your way, you reject it. Fair enough, however I still want to work on these drivers, for they affect me directly.
So, whoever wants to help me and organize some development, please PM me. That is all for now. Sorry if the post seems a bit disorganized, I was a bit in a hurry.
Cheers, Alex. With a little help from Joey on IRC, we determined that the KEXT loads on 10.4.6, but not 10.4.5.
So I assume the Kernel.Framework comes with headers for 10.4.6. This is good news, since now I know that the KEXT I build actually loads and the dependencies are satisfied. This weekend I plan on upgrading to 10.4.6 on my laptop and continue development. Like I said previously, if you wish to help, contact me. I know I will have some difficulties with setting up the Rx and Tx queues, so if anyone with Darwin/OS X network driver experience feels like helping, he/she is more than welcome!
