About SATA / AHCI / RAID Preinstall Drivers:

Download this package if you intend to switch the SATA settings between available modes (AHCI, RAID, or IDE) after an operating system has been installed.

Remember that if you modify these settings without applying the proper files, the OS will not be able to boot until requirements are met or changes are reverted.

As for the installation method, it would be best if you refer to the manufacturer's update guide, read all the steps, and initiate this task only when you have completely familiarized yourself with the procedure.

Even though other platforms might also be compatible with this release, we strongly recommend that you apply the driver only on specified operating systems in order to successfully perform the installation. If a failure occurs, the computer could suffer serious malfunctions.

With these in mind, if you wish to modify the SATA settings according to the mode highlighted in this version, click the download button and make the desired changes. Visit our website as often as possible to stay up to date with the latest releases.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
