Hey  
  
I tried since hours to install on my E6230 Rev. A01 HS. I think I made all correct with different instructions here in the forum. 
  
I used the EFI from Herve above. 
  
But whatever I do (I tried many different settings in the BIOS) clover will not work/boot at all. 
  
Is there any special setting to do in the BIOS? 
  
I really appreciate any kind of support. 
  
PS: On the same notebook I had before 2-3 years successful installed at that time with chameleon an older version of OSX. 
At that time it worked really good.
