thanks artur for the reply.
I used a different compiler , and it gave errors (dsdt editor in windows where i extracted dsdt).
My pc doesn't work under OSX anyway, white screen of death with all OSes i tried (mavericks,yosemite,el capitan,sierra) as soon as the graphical interface loads. I guess it is the hd3000 that is not patched. is there a pc hardware info i can load ?
EDIT / UPDATE : removing IntelHDGraphics kexts it works without resolution/qe/ci . I read it's a 0x0046 device , i guess an old Intel HD Graphics (before HD3000) . Using the patched kexts doesn't solve my problem... any suggestion ? thanks!!
