How to edit bootloader

[Dllop8]

Hi all,

 

I found a solution for my problem with the audio on motherboard DH67BL with audio ALC892, I need to do this:

 

Found the solution myself and its working fine.

 

I have added busdatio=29 in my bootloader.

 

Now audio is working fine in ALC892HDA and voodooHDA as well

 

 

But I don't know how...

 

Thanks for reading.

 

EDIT: I think that the command will be busratio, I just copy paste from other site.
