- go to HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Msahci
- right-click Start in the Name column, and then click Modify.
- In the Value data box, type 0, and then click OK.

  1. 1. you should always backup your registry before making changes.

    2. The techique you tried to use works on Vista and 7, not XP.

    3. I think you forgot to edit a registry key.

  2. i read the article and it only said to modify the value in the msahci do you know the additional one to edit. I made some pictures to show you what im looking at on startup the screen looks like this

    According to the MS document, it states:

    To resolve this issue yourself, enable the AHCI driver in the registry before you change the SATA mode of the boot drive. To do this, follow these steps:

    Exit all Windows-based programs.
    Click Start, type regedit in the Start Search box, and then press ENTER.
    If you receive the User Account Control dialog box, click Continue.
    Locate and then click one of the following registry subkeys:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV
    In the right pane, right-click Start in the Name column, and then click Modify.
    In the Value data box, type 0, and then click OK.
    On the File menu, click Exit to close Registry Editor.

    Notice, 2 keys are listed. Have you tried clicking the "fixit" button to see if it resolves the problem?

    The boot order is fine although I like to have my CD/DVD first, then my hard drive.

    EDIT
    If you aren't using the ESATA ports, disable the ESATA controller in the bios. I think this is why the marvell controller is showing no drives.
  4. I will definately try both thanks for all your help i have been wrestling with this problem for months so disable the external sata 6 or the onboard sata 6? i do have a media carder connected will that affect marvell?
  5. Success!!!!!!!!!!!!!!! Thank you sir God Bless
  6. Great, glad that worked for you.
