There are obvious advantages of using the AHCI disk mode (the most significant example is NCQ). If your motherboard supports this method of reading and writing data on your hard drive you can set the mode in BIOS. From this article you will learn how to enable a faster AHCI mode already installed in Windows® so you don’t have to reinstall the operating system. For more information and steps, follow the instructions below.

Instructions for enabling AHCI mode:

  1. Launch the registry editor;
    Windows XP® – Go to “Start > Run” and type “regedit”. Then, click on the “OK” button.
    Windows Vista® and Windows® 7 – Go to “Start” and in the search box type “regedit”. Press enter.
  2. Find the registry entry: HKEY_LOCAL_MACHINE-System-CurrentControlSet-Services-Msahci
  3. Set the “Start” value on “0”.
  4. Find the registry entry: HKEY_LOCAL_MACHINE-System-CurrentControlSet-Services-pciide
  5. Set the “Start” value on “0”.
  6. Close the registry editor and turn off the computer.
  7. Go to the BIOS settings (press one from Del/F10/F1/F12 key on your keyboard before the operating system begins launching).
  8. Set the disk mode (SATA mode) to “AHCI”.
  9. Save the BIOS settings and restart the computer.
