    Hi, this site will explain what the AHCI is, and why your computer is using it if it is using a SATA HDD, or DVD drive. Hope this helps. :)

    AHCI is an option that MIGHT give you 1-5% performance gain, maybe nothing. It's mostly for "hot plugging" drives. It won't fix the DVD drive. (most likely) You can try it, but don't be surprised if you get a BSOD if you switch to AHCI. You may have to switch back.
