1. Intended audience

This article is for users who want to switch SATA controller from IDE-compatible mode

aka ATA-compatible mode to AHCI mode without reinstalling Windows XP.

Primary motivation for such a switch is to gain additional performance from disk I/O SATA NCQ,

especially for SSD hardware. Also recommendations from this article are useful in

dual-boot configurations, where other OS must use SATA controller in AHCI mode, and Windows XP

as a first OS is using SATA controller in IDE mode.

2. Check prerequisites

Make sure your operating system is Windows XP. If you are using Windows 7 or Vista, then

read this article.

Reboot your PC, enter BIOS setup press DEL or F1 and make sure that currently SATA controller

is configured in IDE mode; and support of AHCI mode exists in BIOS.

3. Find or download F6 textmode AHCI driver for your SATA controller

Find out the name of your chipset south bridge. It should be in the user guide of your

motherboard or notebook, or at the manufacturer s website. Also one can try to find the

SATA controller in the Windows Device Manager under IDE ATA/ATAPI controllers or Storage


Check your motherboard/notebook driver CD, try to find F6 textmode AHCI driver for your

chipset southbridge. F6 textmode AHCI driver consists of TXTSETUP.OEM, one or several

INF files s, SYS file s and CAT file s. SYS file is a driver itself, CAT file is a catalog

of digital signatures to verify integrity of the driver, and INF is an informational file

for Windows operating system how to detect hardware, and how to install/uninstall the driver.

For example, Intel AHCI driver for ICH10R chipset consists of, iaAHCI.inf,, iaStor.inf, IaStor.sys, and TXTSETUP.OEM.

If you could not find F6 textmode AHCI driver on the CD, check manufacturer s website

of the motherboard/notebook, and also check manufacturer s website of the chipset.

For example, for ASUS EEC PC 901 netbook with Intel ICH7-M southbridge, you should check

both ASUS and Intel websites. Also downloading latest drivers from manufacturer s website

may be helpful if old version of driver from motherboard/notebook CD was found, but didn t

work because of alleged bugs. But bear in mind that sometimes new version of drivers has

new bugs, not present in old version.

4. Perform upgrade installation of AHCI driver via Windows Device Manager

Right-click My Computer, choose Properties,

then Device Manager.

Expand IDE ATA/ATAPI controllers, then right-click on

Primary IDE Channel and choose Update

Driver from the context menu:

Choose not to use Windows Update this time:

Choose to install driver from specific location:

Choose not to use search:

Press Have Disk button:

Install From Disk window will pop up.

Press Browse button there:

Choose a folder where you have F6 floppy drivers for AHCI mode of your SATA controller:

Choose a proper INF file AHCI, not RAID if you have more than one:

Click OK:

Click Next :

Click Finish:

Now reboot your PC.

5. During reboot, make configuration changes in BIOS setup

During reboot, enter BIOS Setup press DEL or F1 key and enable AHCI mode for your SATA controller:

Save changes when leaving BIOS Setup.

If you fail to change SATA controller mode in BIOS setup during this reboot, then Windows will

fail to boot with BSoD Blue Screen of Death. Stop code will be 0x0000007B:


6. Verify everything is OK, allow second reboot if necessary

Make sure that Windows loaded normally:

New detected hardware balloons may appear in the tray area after the first reboot after driver update.

Also Windows may ask permission to reboot just after installing the drivers, allow

second reboot if Windows asks for it.

7. Troubleshooting

Reasons why it might not work:

You have downloaded a driver for wrong hardware, not for your chipset south bridge.

You have downloaded a driver for different operating system not Windows XP.

You have downloaded 64-bit driver for 32-bit OS or vice versa.

You didn t switch SATA controller from IDE-compatible mode to AHCI mode in the BIOS setup

during first reboot.

How to undo IDE to AHCI driver update revert to IDE mode :

Download and burn Emergency Boot CD,

you need a full version in this case.

Run EBCD Registry Editor, open


note the value of

Select Current NNN.

Go to registry key


Services pciide

and set value

For example, your AHCI driver is called iastor. Go to registry key

Services iastor

Start 3

it means started manually. Substitute your particular name of AHCI driver instead of

iastor as needed.

Save changed registry hive


F2 and exit EBCD Registry Editor.

Choose to reboot in EBCD main menu, go to BIOS setup and switch SATA controller to IDE

mode before Windows is loaded, otherwise you get BSoD with stop code 0x0000007B:
