Intel Spec Finder (http://ark.intel.com/Product.aspx?id=27228) says it's
'PBGA479' which is soldered directly to the Board, so mPGA479M looked
like the best fit. But the mFCPGA478 works without modifications, so we
may use that.

I have no problem changing the code to 478, i'm just not sure what the
right Socket is.

Sven
