First thing, install Bootcamp 3.0 and updates 3.1 and 3.2
After, from what i can see, you may try to install some drivers from my archive:
- chipset sandy bridge (dble click on infinst_autol.exe)
- facetime camera HD: Try manual install by pointing to the directory (i'm pretty sure it's the same hardware).
- the audio may install also fine...
- the hdmi audio is part of the graphics card and whould also install. Try manual install by pointing to the directory.
also you could try manual install on the LAN and WLAN adapters ("ethernet" and "controller di rete")
After that, the idea is to try every unknown hardware with every driver remaininig : right click > update pilot > choose by yourself > browse and point to each driver directory. If XP recognizes a compatible driver, it will install it.
Once you have tried every hardware remaining with every driver remaining,
- tell me what's remaining
- please click on "resoconto di sistema" under LION and paste the informations here.
We need more info about your hardware (graphics card, etc).
