Some of you might know that AHCI enables Native Command Queuing support and Hot Plugging for SATA drives. Unfortunately it can usually be enabled only when installing Windows, by using a floppy drive.
Spported southbridges: ICH6R, ICH6M, ICH7R, ICH7DH, ICH7M
Instructions:
1) Make sure AHCI is not enabled in your BIOS, otherwise this guide is pointless for you.
2) Back up your Windows folder and prepare a boot disk in case this guide fails!
3) Download 79im05ww.exe from http://www-307.ibm.com/pc/support/site.wss...ocid=MIGR-62909
4) Extract the file to C:\DRIVERS\WIN\SATA.
5) If you have the ICH7M southbridge, go to step 8.
5) Open C:\DRIVERS\WIN\SATA\PREPARE\IMSM_PRE.inf in Notepad.
6) Replace any instance of DEV_27C5 with the following, according to your southbridge:
ICH6R - DEV_2652
ICH6M - DEV_2653
ICH7R - DEV_27C1
ICH7DH - DEV_27C1
ICH7M - DEV_27C5
7) Save the file and close Notepad.
8) Click Start, select Run.
9) In the Open field type C:\DRIVERS\WIN\SATA\PREPARE\INSTALL.CMD and click OK.
10) Restart your computer, and enable AHCI on in your BIOS Setup.
11) Start Windows XP or Windows 2000. The Found New Hardware wizard will start automatically.
12) If running Windows XP:
1. Click No, not this time then click Next.
2. Select Install from a list or specific location (Advanced), then click Next.
3. Select Search for the best driver in these locations.
4. Select Include this location in the search: and specify the path, C:\DRIVERS\WIN\SATA, and click Next.
13) If running Windows 2000:
1. Click Next.
2. Select Search for a suitable driver for my device (recommended), then click Next.
3. Select Specify a location, then click Next.
4. Specify the path, C:\DRIVERS\WIN\SATA, and click OK, then click Next.
14) Click Finish.
15) When the System Settings Change window appears, click Yes. The computer restarts.

Confused here. I'm running a single SATA 250GB drive as my primary boot disk. (Well, I've partitioned it into two, but it's one physical drive.) Intel ICH7R southbridge.
No RAID for me, as I've only got one drive, but what advantages will I get if I run my drive in AHCI mode rather than in IDE mode? Can this even be done - this IS the drive I'm booting from... |

 I am not able to set the BIOS in AHCI modeI use a Asus P5PL2 mobo with Intel ICH7DH southbridge I can see in BIOS that the SATA controller use IDE mode for my Seagate Barracuda disk It is a sata2 disk,and my mobo support sata2 up to 300Mb/s,so I would realy like the sata controllers to work in AHCI mode. When I enter BIOS,under IDE configuration,there is a line called:Configur SATA As..,but the only option is: Standard IDE.As a discription to this option it says:"When in AHCI/RAID mode,controller is forced to Native mode". Can anybody please tell me how to configur my SATA drive for best preformence? Is there a way to configur it to AHCI mode? I hope somebody has time to help me! |

Can't you enable AHCI by just installing Intel's Matrix Storage Manager/Technology?: http://www.intel.com/support/chipsets/imsm/ http://www.intel.com/support/chipsets/imst/ |

OK, nevermind. Now I finally found it in the Intel documenation that you can't install unless you enable BIOS functions before and/or during Windows installation. The support pages on their website made it sound like you just run the .exe installer and reboot.

Nevermind. I ran the Intel Chipset Identification Utility, and it said ICH7DH SATA Controller found in AHCI mode, so its already in that mode, which I realized when I checked the BIOS too.

Tried this on XP x64 - blue screen when loading XP.
Wen't back to native mode, works fine. I'll go AHCI on next reinstall. |

Of course, the driver I posted is for 32-bit Windows.

Any way of making AHCI work on ICH8R based chipsets ?
The driver is only for mobile chipsets. |
