Switch from IRRT to ATA or AHCI for SATA Operations


I have a Dell Latitude E6400 with XP Pro SP3 loaded.  The laptop had the SATA Operation set to IRRT (Intel Rapid Restore Technology) by default and this is how the machine was set up.  We have been having crashing behaviour (blue screen of death and random reboots) and suspect this may be the issue.

We would like to change the SATA Operation to be ATA or AHCI.  When we go into the bios (version A17) and change it to either ATA or AHCI the system crashes on booting.  Can the setting be switched on this XP machine?  It would be very helpful if we did not have to rebuild it from scratch.

What makes you believe that it is the IRRT causing the problem? I don't think that is  very likely.
In order to switch to ATA or AHCI mode you will first have to install the Windows hard disk drivers to support it. It can be done but the only way I know is a bit technical. The directions can be found here.

The reason we suspect this is we have several machines created from the same root image that are crashing periodically. We have not had this problem before. On an older latidute (D530) using ATA we don't have the problem.  We are scambling to find differneces.  We have seen references to folks having similar problems caused by the SATA operation mode (http://forum.notebookreview.com/showthread.php?t=349173).
Thank you for your link; I'll give it a whirl tomorrow.
