Enable AHCI on Intel chipsets


Recommended Posts

Below small FAQ about AHCI

Advanced Host Controller Interface (AHCI) is an interface specification that allows the storage driver to enable advanced Serial ATA features such as Native Command Queuing and hot plug.

AHCI is built into chipsets with the following controller hubs:

* Intel? 82801IR/IO Controller Hub (ICH9R) - RAID and AHCI

* Intel? 82801HEM I/O Controller Hub (ICH8M-E) - RAID and AHCI

* Intel? 82801HBM I/O Controller Hub (ICH8M) - AHCI only

* Intel? 82801HR/HH/HO I/O Controller Hub (ICH8R) - RAID and AHCI

* Intel? 631xESB/632xESB I/O Controller Hub - RAID and AHCI

* Intel? 82801GHM I/O Controller Hub (ICH7MDH) - RAID only

* Intel? 82801GBM I/O Controller Hub (ICH7M) - AHCI only

* Intel? 82801GR I/O Controller Hub (ICH7R) - RAID and AHCI

* Intel? 82801GH I/O Controller Hub (ICH7DH) - RAID and AHCI

* Intel? 82801FR I/O Controller Hub (ICH6R) - RAID and AHCI

* Intel? 82801FBM I/O Controller Hub (ICH6M) - AHCI only

ICH9, ICH8, ICH7 and ICH6-based chipsets, as well as ICH5 and ICH5R-based chipsets, do not use AHCI.

* ESB2 - Intel® 631xESB/6321ESB Serial ATA AHCI Controller -> 2681

* EP 80579 - Intel® EP 80579 SATA AHCI Controller -> 5029

4) Save the file and close Notepad.

5) Run INSTALL.CMD in PREPARE directory.

1) Enable AHCI in your BIOS and save.

6) Start Windows XP, The Found New Hardware wizard will start automatically.

7) Click Cancel

8) Download latest Intel? Matrix Storage Manager from http://www.intel.com/support/chipsets/imsm/

9) Go to Intel Matrix Storage Manager directory and run Setup.exe

10) Reboot windows and enjoy.

is it possible to do the same for windows Vista (already installed)???

plz let me know , its urgent !

Is there any way of enabling AHCI on dell chipsets? it seems like they removed the option entirely from the BIOS, leaving only IDE and RAID.

(Inspiron 530 desktop)

Yes, it is very easy in Vista. Unlike XP, Vista has built in AHCI drivers. All you need to do is to make a regedit, then restart and change the setting in your BIOS.

See: http://support.microsoft.com/kb/922976

You can only enable if the chipset supports it of course, and I'm not sure what proportion do.

In my BIOS, under "Integrated Perhiperals", I needed to change the SATA mode from IDE to AHCI.

I used this guide

http://forums.pcper.com/showthread.php?t=444831

BUt it causes my dvdrw no to see or burn dual layer dvd's ( the drive needs ide mode to function) but when i chnage in the bios, i get a BSOD upon boot! Is there anyway to reverse what i have done, within windows change AHCI to IDE?

Here's how I got AHCI working with ICH10R on an XP SP3 32bit install, Asus P5QL-E motherboard, Samsung F1 SATA drives, Optiarc AD-7200S SATA DVDR. NO XP reinstall or registry hacks needed, just updated drivers, it just took a few minutes.

Backup system first.

D/L Intel Matrix F6 floppy creation s/w.

Create the F6 floppy and copy the several files to C:\AHCI. Also copy one of them, iaStor.sys to Windows\system32 as well (not sure if this is strictly necessary, I think it may stop an error message though).

In Device Manager's IDE Controllers section, right click and update driver on 'Intel ICH10 Family 2 port serial ATA Controller 2-3a26'. Use the options 'Install from a list or specific location', 'Don't search, I will choose the driver to install' and navigate to C:\AHCI and choose iaAHCI.inf as directed. Don't reboot.

Do the last bit all again for the similarly named 4 port driver and choose the default .inf file as offered. Ignore all warnings about the drivers not being compatible, this is true because the drives are currently in IDE mode in the BIOS.

Reboot and go into BIOS to change SATA drive mode from IDE to AHCI. Go into Windows, there should be no crashes.

XP finds new hardware, reboot again and all done.

In Device Manager, the IDE section now has one driver, 'Intel® ICH10R SATA AHCI Controller'.

sbrads,

I followed your guide withouyt any BSOD. Windows boots fine. BIOS detects drives. There were some issues though.

In "IDE ATA/ATAPI Controllers" of device manager instead of saying "Intel? ICH10R SATA AHCI Controller" like you said, device manager has one entry "PCI Device" .

Also, when I boot into windows the add new hardware menu come up, asking me to select drivers etc.... I don't know what to do here...

My mobo is ASUS P5Q3.

Thanks all

I have made some changes to support the latest Intel AHCI for Windows XP 32-bit Pre-Install.

Situation:

Created base image on one Intel AHCI chipset, now when deploying to another PC with a different Intel AHCI chipset, it blue screens.

I have also attached the files as of March 1st 2009.

For those who want to make the changes manually you need to modify the file "IMSM_PRE.inf" with the following. Of course the text may have wrapped, just "un-wrap" it before saving the changes. :D

I have read that NCQ and hot swapping are only really active in Vista not in XP. I don't know how accurate that is but what I do know is I used HD Tach to measure the speeds of my drives before and after enabling AHCI from IDE and they were Identical in XP. The only real difference I saw was when removing the jumper on my Seagate 3G Sata's that stuck them in Sata 150 mode and sped them up considerable.

If anyone is interseted, I found a differnt way to enable AHCI, by doing a non-destructive reinstall and having a floppy ready for the F6 when the install sequence starts. I set my bios to AHCI and Boot from cd first and put in my XP SP3 integrated cd (a non-destructive reinstall replaces the system leaving the data and installed programs intact, but you lose any criticals that are not on the cd, thats why I used an integrated one). Not all slipstreamed disks will have the second repair option, it depends on what you did to it with nlite as to whether the option disappears.

After booting into the XP install disk, and doing the F6 to get the drivers in, the first window talks about a repair but its the recovery console so you instead hit Enter and continue like its a real install. Later after a few more windows and the F8 confirmation, it scans for already installed system files and when it finds your install, it offers a second repair and asks to press R if you want to repair. This is the non-destructive option, if it doesn't show and all you end up with is it asks what partition you want to install to but no "Press R" repair, then your install disk has been altered in such a way that the repair option is gone and you have to F3 your way out and use a different disk or change the bios back to IDE and floppy first.

It takes about 30- 40 minutes to do but the entire system is replaced and any corrupt files are gone and all your data is intact. This type of reinstall has saved my hind end many times, but those special disks with all kind of drivers and themes and programs integrated seem to lose the non-destructive Press R part of the disk, too much screwing around with the iso I guess.

On my XP and XP64 machines I saw no improvement in speed between IDE mode and AHCI, so doing this install really will not get you anything but a clean system (the system speeds up though, just like a fresh install). If you have Seagate drives though, check them for jumpers and remove them. If you don't believe me, download HD Tach, check the seagates speed before and after removing the jumper.

I did it with rather simple method :p I got the AHCI files (inf and all), on Device manager updated the controller driver with those and in my next reboot, enabled AHCI in BIOS and thats it! My system booted was with AHCI mode (painless if you ask me)

I'm damn sure it works!

    • Microsoft: Windows 11 KB5094126, KB5093998 finally stops trusting a critical system threat by Sayan Sen This week Microsoft released the Patch Tuesday updates for June 2026 with KB5094126 on Windows 11 25H2, 24H2, and KB5093998 on Windows 11 23H2. On Windows 10 22H2 it's under KB5094127. Alongside the announced release notes for the new builds, Microsoft has revealed another change that is coming to Windows with these new releases. It has been confirmed that custom folders are getting a significant change with the June 2026 updates as such folders or folder names defined by desktop.ini will no longer appear after this update is successfully installed. While you may inititally think this is a bug with the new release, Microsoft has stated that this is in fact "expected behaviour" in its new support article regarding this which Neowin spotted today while browsing. Essentially it's a security hardening measure such that custom folder presentations are treated as potentially unsafe whenever Windows is not sure about their origin and whether that desktop.ini folder can be trusted or not. Here is list of such untrusted files and folders: Files downloaded from the internet that carry Mark-of-the-Web (MOTW). Files copied from certain remote locations, such as some WebDAV or HTTP-based locations. Files on network paths that are not classified as intranet or trusted by zone policy. For those who may not be familiar, Desktop.ini is a special configuration file used by Windows to customize the appearance and behavior of individual folders. Basically Windows can read specific instructions stored in Desktop.ini instead of displaying every folder with the same default settings. This can be used to apply custom icons, thumbnail images, localized folder names, and such informational tooltips (infotip). The file can also influence certain folder-specific behaviors and properties. It is typically stored as a hidden system file within a folder that has been designated to support Desktop.ini customization. However, because Windows Shell automatically reads and applies these attributes whenever a customized folder is opened, they have historically (since the Windows XP days) presented an attack surface as a result of an unchecked buffer in the Shell component responsible for extracting custom attributes from Desktop.ini files. As such an attacker could create a specially crafted Desktop.ini containing a malicious or corrupted attributes and place it on a network share. So if a user were to browse that folder, Windows would automatically process the file, potentially triggering a buffer overflow. This could allow arbitrary code to run with the same permissions as the logged-in user. Hence a seemingly harmless folder could become a security risk when their contents are not properly validated. For admins and users alike looking to manage this behaviour, Microsoft has shared a few ways. One of them is to assign a trusted mark on the folder in case you are sure of its source. Secondly a policy can be used to revert back to the previous state. Finally, the MOTW can be removed too to indicate to Windows that this is a safe file. The company explains: Option 1: Add the source to Trusted Sites (Recommended) If the affected content is stored on a known internal or managed source, add that source to the Trusted Sites list. Once the source is treated as trusted, Windows processes desktop.ini from that source normally. This keeps the protection in place for other locations and is the lower-risk option. Option 2: Use policy to restore previous behavior Organizations that need broader compatibility can enable the policy Allow the use of remote paths in file shortcut icons.Enabling this policy restores the pre-June 2026 behavior for affected remote or untrusted scenarios. Option 3: Check for and remove the Mark of the Web (MotW) If the desktop.ini file has a Mark of the Web (MotW), Windows may treat it as coming from an untrusted source and block customization. Verify whether MotW is present and, if appropriate, remove it from the desktop.ini file. This can restore expected behavior, but should only be done for trusted content, as it removes the associated security protection. To remove the MotW tag, open PowerShell and run one of the following commands: For a single desktop.ini file: Unblock-File "C:\Your\Folder\Path\desktop.ini" For all desktop.ini files in a folder: Get-ChildItem "C:\Your\Folder\Path" -Recurse -Filter desktop.ini -Force | Unblock-File Microsoft has warned though against using a broad opt-out using the provided policy as it reduces protection against potentially malicious remote folder-customization content. As such the tech giant recommends trusting only controlled internal sources and keeping trust settings as strict as possible. You can check out the official support article here on Microsoft's website.

    • For some reason when EU forced Microsoft to allow users to change the default browser and search provider in Windows (also no ads for Office and the likes) - it was good. But when it comes to Apple - then it's bad. BTW, Apple would have gone out of business if Microsoft wasn't pressed by US government several decades ago. 😉
