OS X86 on Acer Aspire 5520
 

Hi, I'm new to OS X86 and need some support, but first i'll tell my experiences if they can help others with this laptop.
First problem when I tried to install was that installers would not see my internal HD, no way for Kalyway, Ideneb or Leo4all to detect HD so I chose the alternative external USB install. Of all choices only Kalyway made a right install and boot after install, Ideneb would install but no booting after install, no matter the kernel I chose I got kernel panic or restart loop at the grey apple screen; and Leo4all install would freeze at some point.
With Kalyway installed and booting ok I need to tweak now a few things:
-CD/DVD drive not detected
-audio not wroking
-Ethernet or wifi not working
-display resolution fixed at 1024x768

My hardware info:

Any clue?
