Search seems to be down right now, and I can't find where to enable AHCI drivers in Windows XP (lots of solutions for Vista, but none for XP) over the Google.
 
Look down the page at the bottom, Google Search is implemented at the forum until the real search is repaired iirc.

To find the drivers you have to know what controller you've got, which is typically found by reading through the mobo manual, or finding the original drivers either on the CD or the website of the manufacturer. The main ones these days are Intel, Nvidia, SiliconImage still has some out there, SiS, VIA, and maybe a few others, but again you need to know precisely which one you have.

If it's an Intel based chipset, there's a really good chance it's Intel, Nvidia on Nvidia, etc. But until you figure out which controller you've got, you're stuck. There's no such thing as a generic SATA driver (which is where AHCI comes into play) so it's SATA-controller specific.

I'm going to make an assumption that you need the drivers for your mobo, that Asus G33 which is using the Intel G33 chipset. If so, here they are:

The Intel support site is having some issues so, if that's why you created this post in the first place, well... there ya go. :)

EDIT:

After thinking about the OP's statement, I might have misinterpreted it. You enable AHCI support in the BIOS, not in the OS. It's enabled in the BIOS for the SATA controller - some offer AHCI mode, some offer RAID mode, some do AHCI RAID with ATA compatibility, some do SATA and ATA compatibility (the SATA mode works like an IDE controller and without AHCI support), etc.

So if that's the actual case and the question, then that's where you enable AHCI support: in the BIOS using whatever controls and options are available for that SATA controller. After the change is made, you'd boot into XP again and hopefully if you're using the Intel Storage Matrix drivers they'll show you (using the Intel utility on the Start Menu) that AHCI mode is or isn't enabled.
 
The MoBo I'm actually looking for AHCI is actually a 780G running XP that I just built as a HTPC. Does AMD make drivers?
 
Your best bet is to go to the mobo manufacturer's page and find the drivers for your motherboard. For XP, you'll need to get the ones to put on a floppy to load by hitting F6 during the XP setup.
