First of all You need to read the post! Then, I almost sure your bootloader has incorrectly installed (on S.L. partition). Do this:
- save your /Extra folder (in the desktop for example)
- install chameleon RC5 518 (pkg by iFabio from my signature)
- when return to session, put back all your toys (/Extensions) inside the new /Extra folder, including dsdt.aml (mine for 6820s), smbios.plist and com.Apple.Boot,plist (need permissions)
- Rebuilt the Extensions.mkext (cache on /Extra) by dropping the /Extra/Extensions folder to kextutility.app (version 2.4.2 by cVaD)... For your information, Extensions.mkext (/Extra) its necessary for load the trackpad for example. This cache file need to be rebuild any time you touch the /Extra folder (including all inside).
- Reboot, and please tell me other history... Sorry but I dont know why you are so lost? With all the data we have posted here.


I was quite lost because I am a little French frog ;) , It's sometimes not easy to understand everything :).

I did not realize that I needed to rebuild Extensions.mkext each time. But thank you very much for taking the time to explain me how to !!!

My 6820s work perfectly !

I am a happy man :D

EDIT: Now you can use my last dsdt.aml from this post. Its more standardized for 6820s users. Good Luck.


I just tried this for DSDT.aml 6820s, but unfortunately, still no USB ... I compared with the DSDT.aml from BlackCH boot cd, many things look different, but I do not understand much.

Anyway, thank you for the help ;)

You need put (copy) the dsdt.aml (inside BlackCH boot disc) on root directory / or /Extra. Our USB ports not working out of the box (bad bios structure)... thats why its needed the dsdt.aml, for wake up our USB and proper functionality.


I replace with that of DSDT.aml blackCH boot disc, but nothing has changed.
I then try with the files "com.apple.boot.plist", "DSDT.aml", "Extensions.mkext" and "smbios.plist" of preboot.dmg ... it's worse, I lost the trackpad more ...
I am a bit lost, these configuration files bootloader are they the same as the BlackCH boot disc ?

I do not understand why when I boot with the bootcd everything works well, whereas if I use the bootloader installed by HP6720s_Installer, USB ports do not work.

Ideas?

Thanks in advance ;)
