for people who have ich9r, follow the steps from this link http://forum.notebookreview.com/showthread.php?t=164159 however in step 6 where you want to choose the driver to install, choose the Intel® ICH9 SATA AHCI Controller. then continue with step 7. it should boot into windows, which then continues with installation. it will ask for another reboot after it finishes. after the second reboot, it should work perfectly. this method would probably also work for chipsets that support AHCI. unless you want to experiment, please don't try this with a ich9. i did this with an asus p5k-e wifi/ap board.
