ICH10R/P45 - changing from IDE to ACHI?

[iCe-BLaZeD]

hey guys, is it possible to change from IDE to ACHI without re-installing etc?, whenever I change it in the bios it BSODs on windows logo.. I assumed this was because I hadnt installed the intel matrix drivers/software but I cant find one that will install they all say "your system does not meet requirements", is that because im on windows 7 64bit b7077?

thanks

sorted this ended up resorting to re-alligning the drive since I wanted to change offset then reinstalling windows 7 when the drives were set to achi mode

so sorry didnt see the replies but thanks for them guys! <3

well maybe it was just the allignment that changed it then but I am getting much better benching on my vertex now, before I was getting around 50-65% of what I should have been getting

do u think "raid" would be better?....
