You need the Intel Matrix Storage Drivers. This is the AHCI driver for Windows.
I bought a floppy drive for my system so I could install from F6 when installing Windows. (XP x64, and Vista). Unfortunately, that's the only way I've done it at boot. With XP you can only install at boot from a floppy. In Vista, it's now possible to redirect the installer to a USB key or other external drive. *see below.
Conversely, you can install Windows first (with AHCI turned off) and then install the drivers afterwards. I've used this guide to enable AHCI after I installed Windows XP x86 before I had a floppy drive, and it worked fine. I used Windows XP, not sure, but I think Vista would be the same, just use the Vista driver from Intel.
*I think you can also use the above method to extract the drivers from the floppy image to a USB key or other device, for use with an F6 install at boot- from another Windows machine of course.
(By the way, the 2nd step in the post-install instructions can be very confusing. Basically, you need to use the command line (start/run/ cmd) navigate to the directory where the file in question is and enter the downloaded filename -a command.)
After installing the driver, you can then turn AHCI back on.
I would recommend keeping AHCI on for the sake of the Mac OS side. I notice much better drive performance in OS X with AHCI. In Windows, there's no real noticeable difference, just it's a PITA to keep switching it on and off when you want to boot into either OS.
