Thanks , will try it out.
Just to make sure I understood correctly , this is what I am supposed to do:
The above script is a patch for my dsdt.
I will save it as a txt file (e.g acer.txt)
I will extract my dsdt using dsdt editor or something similar.
I will apply the patch to the dsdt
recompile the dsdt
save it as dsdt.aml (e.g on my root directory)
refer to in in chameleon config file during boot (org.chameleon.Boot.plist ->DSDT=hd(0,1)/DSDT.aml)
Is this correct ?
