How to patch a kext which does not contain a DeviceID?

Recommended Posts

New to HAckintosh and patching. Looking to to try and patch a Kext for Mountain Lion ( ATI3800Controller.kext) as I have a ATI3600 (PCI-E) card and wanted to try it. I have the PNPID as 0x95981002 as required and I am following this guide http://wiki.osx86pro...t_Patching_List . My problem is that the info.plist is clearly for ATI3800 so may work but does not contain a section <key>Device Name</key> followed by a <string>0xABCD0EFF</string> for me to replace.

  1. Am I completely off track and that this is not feasible or of so how do I try and trick the kext to be used for my device (if I need to add a section where should I do this)?
     
  2. Do I need to change all the references to from ATI3800 to ATI3600

Thanks

 

Update: have found a string that is 1002,0x1234 so worked out it is this.

Newer issue, found Chimera supports lots of AT 3600 but not the specific Device ID e.g. supports 9589 and wondering how I change or inject my ID

copy ATI 3800 kexts to desktop open contense copy plist info

open plist info with text editor add device id to it

below the id you are using or your hackintosh and . add you id vender then deviceID TO the string with a space. between each id in it. repair permissions and load with kext wizard . back up the kext. with it kext wizard.

Thanks. Can I do this after install and the installation will still find it on next boot provided Device Id is correct even though it is 3600 and the file refers to 3800?

Thanks - tried kext it but did not work - even if ID is in both files. Oddly using Graphics Enabler ifI set screen in Chameleon Wizard to 1680x1050 it uses 1400x900 and yet if set to 1400x900 uses 1150 x850 - weird seems to use one resolution lower

    • all the possible frequencyes i have added seems to work fine at the moment, i have added a lot of different frequencyes to support better all kinds of professional applications, inclunding strange sampling rates and goes from 8khz up to 176.4 khz, unfortunately 192 khz does not seems to work even on cards which should support it like the audigy rx, but other frequencyes just works fine and at the moment i have tested only the sound blaster audigy rx and the audigy sb0090 (1st gen audigy) and i can confirm that all the frequencyes from 8khz up to 176.4 khz does work on that card, so i think that such frequencyes should work on all the audigy 2, 2sz, 4 cards as well, tomorrow i will test with my sound blaster live! cards and i will let you know, but here are also some photos (pro tip: use cmd + alt/opton + 4 and then press space to make a screenshot of a single window):
    • Guy's if something happened, this is most likely Admins and Moderators are working there, yes we still need some things to be done, but if it's still not yet, it's because of time or something we don't know, we just have to be patient! Slow things is just because they are working in the same time, patience for that problem is good, and loading things, but apparently now is good, for me these things I've accounted them yesterday and this morning, but now they are gone. For the missing things like the Old insanelymac and theme, please we need them, and excuse my ignorance!
    • Good evening to all. So, I have an external 1TB seagate HD and it always reads normally, but now when I plug it into my HACK it just does not read, it does not even appear on the disk utility. The light always turns blue from the HD without blinking. However I plugged it into windows, on a macbook and it worked normally. I already formatted my hack but it did not work. Thank you in advance for the help and sorry my bad english   my kexts: AppleALC.kext FakeSMC.kext IntelGraphicsFixup.kext IntelMausiEthernet.kext Lilu.kext WhateverGreen.kext VoodooHDA.kext USBInjectAll.kext NvidiaGraphicsFixup.kext   GTX 1080 Windforce core i5 7º generation 8gb Ram H170M Plus BR

    • For me the forum seems reasonably OK, except whenever I see the word 'LOADING' - like when clicking another page of a thread - when it just stops completely and never returns.   I use an adblocker, so adverts aren't slowing me down.  Browsing the forum indexes is not too bad, as is clicking to view any thread.  Ditto clicking a link in an email notification to go to a particular post in a thread.  Sometimes it takes maybe five seconds to load a page, which is a bit too long.  But it's not terrible.   But then whenever I click on any other thread page, which tries to do the in-page content load (without a full page refresh), I see LOADING and then nothing further happens, even after minutes.   It's definitely not related to which content is loaded, but rather how it is loaded.  For example if I go to the index for this forum, then click directly to page 11 of this thread, it loads in 1-5 seconds.  But if I click the link to page 11 within the thread, it never comes back.  I just see this, forever:     This stuck issue seems to me likely something broken (code or configuration?) rather than a general slowdown.  But maybe there's also a general slowdown, especially for those who are seeing adverts.
