AHCI drivers?

Hello!
I was recently browsing the Asus site for driver updats and noticed that under the "utilities" section there was driver drive called "AMD AHCI Driver V3.2.1540.35".
I have never updated this, and I do use AHCI seeing as I have SSDs.
I simply need to know what the update will do and what purpose it serves.
Or if there are any patch notes.
My MOBO is a ASUS M4A87TD EVO.

  1. It was a driver released in Sept 2010. If you are not having any issues then you will not need to update and possible you already have it installed.

    Would there be any way to check to see if I have in-fact already installed said updates?
  3. In device manager you should be able to look up driver versions.

    I see, under which utility would I need to search?
  5. It would be under disk controllers.
  6. I see, thank you very much for your help!

    It would not damage anything to just download and install the driver. Probably some bug fix with somebody's third party hardware.

    Yeah, there was no problem with the device.
    I was simply looking through the latest drivers omy MOBO page and noticed that I had never installed it.

  10. To install the AHCI driver you have to have AHCI enabled in the BIOS. You cannot enable AHCI in the BIOS and get the computer to boot without reinstalling the operating system.

    Not a true statement... All you have to do is have the BIOS set to IDE than follow the steps in this post: http://support.microsoft.com/kb/922976 , than reboot, adjust your BIOS to AHCI and reboot. You'll be good to go!!
  12. Thank you tecmo34 I didn’t know that Microsoft had issued a fix for this problem that is why I read theses forums you learn something new everyday even though I have been fixing computers for the past 35 years.

    Thanks SO much for the tip tecmo34! I was about to return the mobo. Even ASUS support told me it must be defective. I love these forums! Someone almost always has the answer (they're out there!)
