AHCI on XP for Latitude E6400

woodyg

Hi i have been trying to find a way to install AHCI drivers on an existing XP Sp2 machine as i would like to use the e-sata connection to recover a dead drive.

I have tried a few how to's from the net i.e. http://forum.msi.com.tw/index.php?topic=106575.0
http://www.tomshardware.com/forum/238806-45-switching-ahci-mode-reinstalling

i have had no luck as yet still get the BSOD and have to go back to use ATA operation which stops the e-sata support.

Any one ever get this working with out slipstreaming an XP fresh install.

Yep, this should do it for you.

- Save a recent copy of iaStor.sys into C:\WINDOWS\system32\drivers. You can get it from here

- Import the following code into the registry by saving it as a .reg file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor]
"Group"="System Bus Extender"
"ErrorControl"=dword:00000003
"Start"=dword:00000000
"Type"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\PCI#VEN_8086&DEV_2929]
"ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}"
"Service"="iaStor"

Now reboot the machine and change the SATA mode to AHCI. It should detect the AHCI controller and prompt you for the driver, which is in the download I linked to above.
