From yesterday, I have been trying to turn my HP G62-B12eo to Hackbook. The only working this is Atheros  AR9285 WiFi. My graphics card ATI 5470M is also working oob but it cannot recognise my internal monitor.


On boot, kernel chooses Eumelar as default device frame buffer, but when it comes to start screen it shows a White screen. I have to connect the laptop with external screen with VGA cable in order to see an image.


I have tried to inject edid in DisplayVendorID-756e6b6e and DisplayProductID-717 ... but it still can´t recognise the edid. Can anyone help me with this {censored}!!


I have attached IOReg and DisplayId-717 file


VGA Profile looks likes this:


Attached File  screen.jpg   55.47KB   0 downloads


Edit: Using chimera as a bootloader, Couldnot use Clover as it gave boot0: error and dd if=/... didn´t fixed it.

If I use kernal flag, AtiConfig=Hoolock then I have to connect laptop to HDMI cable, then I can use internal monitor (Really weird)


Thank you!
