Enable AHCI on Intel chipsets


Recommended Posts

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...

As I said in the first post:

AHCI enables Native Command Queuing support and Hot Plugging for SATA drives

:no: I am not able to set the BIOS in AHCI mode

I 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?:

I literally spent a DAY trying to get AHCI to work. I was trying to load WMCE and after pressing F6, loading the drivers, and watching Windows install....my PC would crash and reboot at the Loading Windows screen (the one you see right after post with the animated bar).

I tried everything I could think of (believe me....that is a lot of stuff....I'm 39 and been building PC's since I was 12)

THIS WORKED LIKE A CHAMP!!!!!!!!!!!!!

THANK YOU, THANK YOU, AND THANKS A HECK OF A LOT!!!!!!

:D :) :laugh: :rofl: :woot: :yes:

One note for anyone attempting this procedure. In step 6 the instructions say REPLACE. Notepad has a REPLACE feature. USE IT! It will keep you from making a typo like another poster did.

I would like to know also how to set sata on bios and which driver install. i have read of ahci but i don't understand very well what is it. thank you for your help and sorry for my bad english

Here is the solution (it worked fine for me)

With the BIOS on IDE open Regedit and go to:

HKLM\System\CurrentControlSet\Services\msahci\Start

and change whatever you have on DWORD to '0'

Raboot

Reboot again, enter BIOS

Change IDE to AHCI, Save

Let the OS redetect your drives

Reboot

That's it, hope it helps

Any news regarding this guide but with the ICH9 chipset?

I have the P35 chipset w/ ICH9 (Gigabyte P35-DS3R)... with an existing Vista installation I did this:

HKLM\System\CurrentControlSet\Services\msahci\Start

and change whatever you have on DWORD to '0' (default value was 4)

like Ropera mentioned, I installed the Intel Matrix Program/Drivers, rebooted went into Bios... changed from RAID/IDE to AHCI save and everything went fine...

  • 2 months later...

I used that method originally on my Asus P5W DH Deluxe for both Windows XP 32 bits and Vista 32 bits but now I have a double problem:

Now I have a Asus P5K Deluxe with ICH9 and I'm with both Windows XP and Vista x64 edition.

So instead of this drivers version on the firts post (http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-62909), I'll have to get another one right?

I have the P35 chipset w/ ICH9 (Gigabyte P35-DS3R)... with an existing Vista installation I did this:

HKLM\System\CurrentControlSet\Services\msahci\Start

and change whatever you have on DWORD to '0' (default value was 4)

like Ropera mentioned, I installed the Intel Matrix Program/Drivers, rebooted went into Bios... changed from RAID/IDE to AHCI save and everything went fine...

Can you post a print screen of all DWORD keys you have under \Start forlder? Inside mine HKLM\System\CurrentControlSet\Services\ it doesn't even have a \msahci or \msahci\Start forlders, I'm confused :wacko:

Please help me, I'm desperate.

    • A different thing with Russia. When you say is it better, depends on things. It is better that we don't have the E.U making rules and laws that have nothing to do with them. Is the trading part better? No, that is really mucked up, but then we knew that was going to happen and we would have make agreements, like we do with other parts of the world. Freedom of movement is certainly better, but could be improved, we still need more control over our borders. do you live in the U.K?
    • So what am I quoting from them? I never listened to what Farage or his cronies said. I wanted the U.K to leave the E.u years before the referendum and it had nothing to do with Farage and his cronies. So what country do you live in? Did we work much better together? We were always at logger heads with the E.U because we disagreed with them so much. Maggie was always on at them. I would have thought the E.U was glad to get rid of us as we stopped the integration or made it a two tier. Now without us they can integrate more. I would not have voted out if it was just a trading block and we can still work together on somethings.

    • Apple reportedly looks to blacklisted Chinese memory chips as RAM prices climb by Karthik Mudaliar Image via Apple Apple is reportedly trying to get a clearance from the Trump administration to buy memory from ChangXin Memory Technologies (CXMT) to get some relief from soaring DRAM prices. As per a report by the Financial Times, Apple approached the Commerce Department more than a month ago and also spoke to other officials and allies in Washington. For starters, CXMT is a company that's already been placed on the Pentagon's list of Chinese military companies. The Chinese company is the country's top DRAM maker. For Apple, the timing is certainly awkward but not surprising. Tim Cook had recently warned that Apple would have to raise prices because AI companies are buying up large amounts of memory for data centers, and just like that, Apple raised MacBook and iPad prices. Micron also recently revealed that customers have committed billions of dollars to secure memory supply years in advance, which shows us how aggressive securing infrastructure has become. This gives suppliers such as Samsung, SK Hynix, and Micron more leverage, while pushing hardware makers to look for alternatives. CXMT is one of those alternatives, but not the simplest one. Apple has spent many years trying to diversify parts of its supply chain away from China, especially for final assembly, while still depending heavily on Chinese manufacturing and suppliers. Even domestic brands from China are moving towards CXMT and YMTC instead of relying on Samsung, Micron, and SK Hynix. For Apple, though, it would invite more scrutiny than local Chinese companies. For now, this is more like a lobbying effort rather than a confirmed supply deal. There's no official statement from either of the parties. What is clearer, though, is the pressure behind such a request. AI demand has certainly made hardware a bottleneck, and companies are trying everything they can to bring things back to normal, even if that means making politically sensitive choices.
