quick respond to Ken: I don't even have AHCI enabled in bios. it's set on IDE. Googled the problem, seems that I have to reinstall my windows if I wanna use AHCI or try to do some registry modification. Found a tutorial on that. As for updating AHCI drivers, I found them on AMD website. I will give it a try.
OK. BACK! I can't use AHCI. If you put the SATA controller in AHCI mode, and try install Windows, it will it seas,can't find a storage controller on your computer and abort the installation. In this case,somebody told me that I need a floppy drive and a floppy disk with the native SATA drivers on it. Press F6 when prompted during the Windows setup to have it load the drivers from the floppy. So complicated
Just to install AHCI
