I've been getting flooded with emails and PM's requesting how I enabled AHCI on my iMac, so I figured I should just post my reply here. I went ahead and used the same procedure that has worked for the 2011 MBP's. I found this post on OCZ's forums to be the most helpful: http://www.ocztechnologyforum.com/f...ing-AHCI-for-Windows-on-MBP-2011-now-possible So far everything has been working great, except it seems that my SSD's 4K reads / writes could be a little better than they are (the 4K QD32 reads / writes are fantastic though) but they are still way better than IDE mode. I did this about a week ago and, so far, Win 7 has worked great in Boot Camp and Parallels. Highly recommended for any Boot Camp SSD users! EDIT: FYI, I also had updated my drivers from MS to Intel. One person has mentioned that the Intel drivers on his MBP with Crucial M4 slows down after a while and that it speeds back up after a reboot. I haven't been able to confirm this on the iMac though.
