P55A-UD4P XP and AHCI

[JoeG]

I installed XP using F6 method for all 3 controllers RAID/AHCI. Intel controller bios was set to IDE, Native mode. Install went OK

HD is SATA II

I then changed Intel controller bios to AHCI and during boot received the BSOD.

What am I doing wrong

when you change your bios setting Intel controller bios from IDE to AHCI or Raid, you need to re-install OS. the OS can not be shared with different mode (IDE or AHCI).

Yes you must have the IDE/AHCI/RAID mode set before you install. F6 loads drivers need for install, but if they are not needed (no AHCI detected because it's set to IDE) then they do not get installed. Set the mode to AHCI and install the drivers by F6 when prompted.
