Hmm strange, I can't get 2012 to install on my Poweredge 2800 with Perc 4e/Di with the 2003 x64 driver. I also have a 2800 I use for testing with a Perc 4e/di and am trying to install 2012 standard. I downloaded the 2003 x64 driver and after loading it during install cannot see any storage.
Am i missing something obvious? How were you able to install with the 2003 x64 driver?`
