[dave20v]

hi all

 

managed to get 10.8.5 working fine on the dell 17 xps 17 l702x

 

spec is i5 2540m 

 

8gb ram

250ssd for windows 8.1

120ssd for mac os

 

its got the geforce nvidia 550m 1gb but i have that disabled

the one im trying to get working is intel HD3000

 

ive played about with the DSDT injecting dual link etc but i cant get higher then 1280x1024 res

and its only showing 64mb shared memory??

 

any ideas

 

uploaded the DSDT file
