XP: How to change from IDE to SATA/AHCI?

[Nomen]

I've got a system running XP on a Gigabyte GA-EP45-DS3L board and found that the SATA controller was set to IDE in the bios (the system has no actual IDE drives - they're all sata).  Changing the setting to AHCI resulted in a system that wouldn't boot.  Changing back to IDE and booting back into XP, did some poking around and it sure looks like the SATA drivers are installed.  So what exactly needs to be done to prepare XP, while it's running, to prepare it for the next boot when the BIOS is changed from IDE to AHCI mode?

See link given here:

Make sure that all the drivers are actually installed and compare with that set of instructions (they may be inaccurate, it depends on the specific drivers you need).

Otherwise you will need to try a driver injection tool, right now the references I have on 911cd (gone for good) and reboot.pro (hopefully only temporarily down) are unavailable.

First thing:  As a result of fooling around with swapping the Q8200 core2 cpu with a xeon cpu (had to mod the bios to do that) and disabling the on-board IDE controller in the bios, XP decided that it needed to re-validate itself, which I got a chuckle from and I did do the re-validation and checked using XPinfo.exe and I'm back to full-power valid state.  The board is now running with an E5450 ($25 from ebay).

Second thing:  Intel ICH10 2-channel and 4-channel SATA controllers now show up in device manager in the hard drive controller tree, in the same branch as the ide controller devices (which still show up despite having disabled the IDE controller in BIOS?).  In XP, do SATA controllers show up under a separate branch in device manager, like they do in win-98 (typically or always as "SCSI" controller) ?

Third thing:  BIOS is still set to IDE-mode because XP fails to start when set to AHCI (a blue-screen with some text flashes briefly during XP-spash-screen before the screen goes black).  But (as I said above) SATA controller shows up in device manager as "present and working" so I don't know how both of those things can happen at the same time.  My primary question now is -> what sort of utility program can I run to know exactly if the drive is being controlled under a "SATA" paradigm or an IDE paradigm?  Device manager does not explicitly give that information (it does not say which controller the drive is connected to) but a thought just occurred to me - there are different device-views in device manager and I haven't tried them all yet...

I had this problem with my dual boot netbook that it would boot fine into Windows 8.1 in AHCI mode, but not into XP.

Installing the Intel Application Accelerator fixed it perfectly for me, but I don't know if that was the preferred solution!
