HOW TO switch from IDE to AHCI mode without having to reinstall Win XP (GUIDE)

[Jack t.N.]

Have you done exactly what I described in my first Post?


First Step:

Open Windows Notepad and create a REG-file and name it as you like (example: AHCI.reg)

Copy and paste the following lines into that reg-file and save it:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\pci#ven_8086&dev_2821&cc_0106]
"Service"="iaStor"
"ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor]
"Type"=dword:00000001
"Start"=dword:00000000
"Group"="SCSI miniport"
"ErrorControl"=dword:00000001
"ImagePath"="system32\\drivers\\iaStor.sys"
"tag"=dword:00000019
"DisplayName"="Intel AHCI Controller"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Parameters]
"queuePriorityEnable"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Enum]
"0"="PCI\\VEN_8086&DEV_2821&SUBSYS_B0051458&REV_02\\3&13c0b0c5&0&FA"
"Count"=dword:00000001
"NextInstance"=dword:00000001

Now double-click on your reg-file to make the above changes to the Windows registry.

Do not restart your computer at this point.

Second Step:

Copy the iaStor.sys-File into the \Windows\System32\Drivers\-Folder if it isn't in there already. 

The file is part of the of the Intel Matrix Storage Manager-Packet (IATA621_CD.EXE) and can be retrieved manually:

\START\Run --> IATA621_CD.EXE -a -a

After entering this command the file should be in the following folder:

...\Program Files\Intel\Intel Matrix Storage Manager\Driver

...and ready to be copied.

Third Step:

Restart your computer, enter BIOS and switch to AHCI-mode.

Save, exit and load Windows XP which should now start properly, discover the SATA AHCI Controller and ask for a driver.

Abort the whole Windows-Driver-Installation procedure and run IATA621_CD.EXE instead to take care of the installation.

Restart your system.

hello jack,

some feedback:

I have tried your guide on my 975 powerup (windows xp home) and it worked right away...

after running that registry file i restarted my computer and changed the setting to AHCI mode. 

windows booted without any errors and found the ahci controller

i took care of that and didn't run into any problems so far.

@Jack the Newbie (and others):

I got some new drives (see sig), so I just used your guide to integrate AHCI drivers. Works perfectly, thanks for posting it. Now I'm trying to get my RAID 1 array going, setup of the array in Intel Storage DOS util goes fine. But then I try to boot from the single drive, BSOD when WinXP loads. I can now only boot into Windows when BIOS setting is set to AHCI, not when set to RAID.

I guess it's a driver related issue, but in AHCI mode my RAID 1 array is not there so installing drivers proves pretty difficult. Some advice anyone? Thanks...   

[Jack t.N.]

I am glad to hear, that the AHCI-guide worked (this applies to butterfield's feedback as well). 

I will post the content of a REG-File that was intended to allow switching to RAID-mode and basically affords the same procedure as I described before.  I have not tried it myself but maybe it will help you and it might be worth a try in your case:

Windows Registry Editor Version 5.00

"NextInstance"=dword:00000001

[Quadrifoglio Verde]

Thanks for the quick response...

I guess I was too quick with my post, it's seems to be working after all in AHCI mode. I'm copying some data to the array right now, to see if everything is working like it's supposed to. If not, I will give this new .reg file a try and let you know how it works out.

[Maesus]

All, I perform the very same guide as Jack The Newbie posted, and it does work on my C2D with Vista 64-bit.

[Viktor92]

All, I perform the very same guide as Jack The Newbie posted, and it does work on my C2D with Vista 64-bit.

Have you seen any perfomance difference ??

[obvious]

ok, just for fun I tried this on an Abit i90HD under Vista32

Everything goes to plan until the reboot and then I got the dreaded STOP: 0x0000007B (inaccessible boot device) while loading crcdisk.sys

Had to revert to standard IDE mode under SATA options in the BIOS.

Just thought I'd mention it. I thought about maybe changing the vendor ID string but I think it's Intel anyway so that would remain the same.

The only thing of note is that there's an IaStorV.sys in system32/drivers as well as knocking about in similar registry corners.

[Jack t.N.]

I am not sure, but doesn't the Abit i90HD use an ATI Radeon Xpress 1250 Chipset?

ah, erm, yes  sometimes I forget who's in bed with who driver wise.

Excuse my interruption, I have just purchased a new Motherboard with an NF650i Chipset, I have two SATA DVD-RW Drives and 2 SATAII Hard Drives, I've read that in order to make the SATA DVD-RW Drives work, I need to set the SATA controller to IDE mode...

Is this true? Or will the SATA DVD-RW Drives work in AHCI mode?

I haven't installed Windows yet and my biggest fear is that the DVD-RW Drives will become unavailable and screw up the Windows install, I know about the Hard Drives, press F6 during setup to install the driver etc, but what about these DVD-RW Drives?

Any and all answers are welcome, please help if you can, I've never used SATA before, everything has always been IDE.

Thanks.

[Jack t.N.]

This thread may not really be the right place to discuss this.  Anyway:

Is this true? Or will the SATA DVD-RW Drives work in AHCI mode

This is not true, at least not in generell.  I am using a SATA DVD-RW drive in AHCI mode on my 975X Plat. PUE-mainboard and did not have any problems.

[Bannik]

I am using a SATA DVD-RW drive in AHCI mode on my 975X Plat. PUE-mainboard and did not have any problems.

Did you install Windows OK with the SATA in that setting?

[Jack t.N.]

No, I never tried that with XP. However, it worked fine with vista.

Slipstream SATA drivers into a new XP-Install-CD using XP ISO BUILDER and try if it works.  I don'really know, why this should be a problem.

[Bannik]

Well, thanks for your assistance, I guess it will be trial and error.

[uid313]

Third Step:

Restart your computer, enter BIOS and switch to AHCI-mode.

Unfortunately, my MSI P35 Neo-F does not have any AHCI setting in the BIOS. 

[Jack t.N.]

Are you sure?  Have a look here in BIOS:

Integrated Peripherals --> On-Chip ATA Devices --> On-Chip SATA Controller --> ?? ??

[Bob the Fish]

I have the 975X Platinum PowerUp Edition bios 7.50 and have followed all steps listed. I get a BSOD when i turn on ACHI in the bios after adding reg file info and then puting iaStor.sys into the \Windows\System32\Drivers\ folder. could it be beucase of a new iaStor.sys from Intels matrix storage manager? i have the latest one from there web site. Not sure what rong any help would be cool.

[Jack t.N.]

What Windows Version are you using?

[Bob the Fish]

XP pro SP2 up to date as of today.

[uid313]

Are you sure?  Have a look here in BIOS:

Integrated Peripherals --> On-Chip ATA Devices --> On-Chip SATA Controller --> ?? ??

That is the one? I have that one...
I expected it would be an entry named "AHCI" something.
It can only be set to "IDE" and "Disabled", I think...
Confusing...

[mattyboy]

Can you use ACHI and a RAID 0 array at the same time. Like, have ACHI set in BIOS for a RAID array? Probably not right?

[Heart_Sailer]

will it work on Windows Vista too ? i have P965M Platinum with 320GB of Seagate 7200.10 HD.

I install both Vista & XP with dual booting.

[roguepenguin]

Bob the Fish-

I have the same setup - 975x PUE BIOS 7.5 (although I backed down to 7.4 and had the same issue). BSOD while following the procedure. The device ID used in the reg file in this thread does not match my machine, either. Is this the case with others?
entry from the reg file here:
ven_8086&dev_2821&cc_0106

entry for my SATA controller:
ven_8086&dev_27c1 <-- AHCI mode
ven_8086&dev_27c0 <-- IDE mode

even with the patched entry, it does not work. Upon reenabling IDE mode, I get a device listed in the registry at HKLM\SYSTEM\CurrentControlSet\Services\iaStor\Enum
0 = Root\LEGACY_IASTOR\0000

(The name of this key shows as "1" instead of "0" if you imported the whole registry file from here, which defines "0" already.)
Any ideas?

XP SP2
MSI 975X Platinum PowerUp Ed.
80GB Seagate 7200.10 drive

FOLLOW UP (SOLVED) -

I got angry and forced the regular SATA driver to be replaced by the AHCI Controller driver in the device manager, rebooted, turned it on, and now everything works.
Go figure.

This tweak didnt work at first with my board. After some search seeing its coming from a ICH8 chipset i altered the device 2821 values in the reg code with the corresponding to ICH9R, 2922. Heres how it should look:

Also The iaStor.sys ofcourse can be extracted from the latest matrix storage manager downloaded from Intel site (something like iata78_enu.exe). And its installation files that are being unpacked with the -a-a parameters are found in the Program files folder in the boot hard drive (eg C:\Program Files\Intel)

[Jack t.N.]

Thanks for your update.   

[monographix]

ur welcome 

[marcovtje]

I wasn't trying to disagree with you or your excellent guide. I just wanted to make people aware of the possible disadvantage of NCQ. Simply stated, for most desktop users NCQ is not worth enabling. Marketing is trying to make us believe otherwise...

In years long gone by I used SCSI drives on the desktop. Enabling NCQ on a good host adapter (and even cheaper ones like the later Symbios logic) provided a great boost for compiling.

The ultimate test I'd like to see is e.g. a Linux kernel compile.

(p.s. I'm reading this btw not for the XP side, but I hope that AHCI mode might kill some of the bios bugs of my (plain) P965-F )

Thx for this thread Jack the Newbie and thx for the MSI Neo2 update monographix !! You saved me a lot of time !!

I've got a dual boot XP Pro/Vista Ultimate and it works the same way, except that you need to replace all "iaStor" occurences (without quotes ;-) by "iasStorV" for vista reg file ...

btw, I use AHCI for eSata "hot plug"...

HTH and... Thx again!!

hi,

I did all the steps many time and always the same death screen.

my configuration:

-xp pro Sp2
-motheboard Msi platinium 975X powerup (ICH7DH) with the last update.
-I used IATA621_CD.EXE to extract iastor.sys (I did also a test with iata75_cd)
-for the reg file I used :

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\pci#ven_8086&dev_2821&cc_0106]
"Service"="iaStor"
"ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor]
"Type"=dword:00000001
"Start"=dword:00000000
"Group"="SCSI miniport"
"ErrorControl"=dword:00000001
"ImagePath"="system32\\drivers\\iaStor.sys"
"tag"=dword:00000019
"DisplayName"="Intel AHCI Controller"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Parameters]
"queuePriorityEnable"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Enum]

"Count"=dword:00000001
"NextInstance"=dword:00000001


and after hours nothing... :bon
someone can help me ?   
thanks

If the procedure I described in the first post of this thread does not work, you have to re-install Windows XP with AHCI mode enabled and integrate the drivers during setup.

Well thanks for your answer, 
but I am asking a question ; why some people (in this tread) having the same system like me (motheboard Msi platinium 975X powerup /Xp pro Sp2) the steps works ? 

thanks again 

[Jack t.N.]

I don't know.  I worked on my system and I have the same board + OS.

Try the following content for your reg-file and see if that changes anything:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\pci#ven_27C1&dev_2821&cc_0106]
"Service"="iaStor"
"ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor]
"Type"=dword:00000001
"Start"=dword:00000000
"Group"="SCSI miniport"
"ErrorControl"=dword:00000001
"ImagePath"="system32\\drivers\\iaStor.sys"
"tag"=dword:00000019
"DisplayName"="Intel AHCI Controller"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Parameters]
"queuePriorityEnable"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Enum]

Re-hi,

Forget my last question, now it's working fine  ,
-I just changed the sata connection for the boot hardDisk (to the blue one under Msi platinium powerup).

when I reboot all is ok, nothing different, intel Matrix storage works .

-strange thing, the boot hard drive in materiel propreties it's writing "Sata maxtor 7 scsi disk device"
 but this hard disk is not "scsi"..?

anyway thanks again

I just changed the sata connection for the boot hardDisk (to the blue one under Msi platinium powerup).

You mean the connector that stands a little seperated from the other four? That port is hosted by the JMicron Controller, not by Intel ICH7DH...

That also explains why it is listed as a SCSI Device:

http://www.jmicron.com/Driver.htm

Click on "FAQ" and you will find this info:

JMB driver base on Windows SCSI mini port driver architecture , if any device attach on JMB controller will be an SCSI device.

So after all, what you did there may have worked, but it has nothing to do with the procedure.

[nexusfr]

yes this connector 

I really dont know why this procedure dont work with me, I did all the steps many time,   lot of people having this Mb and it works good


-my xppro is up to date and very stable.

is there any other solutions ?

Actually, re-installing Windows with AHCI mode enabled in BIOS IS the standard procedure.  The steps decribed here are meant to provide an alternative that works in many (but unfortunately not in all) cases.  There is not much you can do but to reinstall XP and integrate the ICH7DH AHCI drivers during Setup.

Just for fun I tried to switch from IDE to AHCI mode using this method on the rig in my sig (P35 chipset).
I followed the guide to the letter but blue screen anyway. Has anyone successfully used this method on a
P35 chipset?

Yes and P965, I wish hadn't on the P35 though Hard disk is slower now........

Yes is NCQ hard drive..... win some and lose some

On P965, it's great...........

Will be doing a re-install on P35 and see if F6 option is any better.....
