ive got a p5b-d, 1 80gb WD caviar se, and 2 250gb seagate 7200.10's. when i go in to the bios and change SATA as IDE to SATA as AHCI, save and exit, windows wont boot.

do i really need to set it as AHCI. does it make any difference, speed wise?

Setting AHCI on shouldn't make much difference, as I understand it all it does is enable NCQ etc through a generic driver. I had all sorts of problems doing the same thing on my machine - turned it on and the machine BSOD'd at boot.

See if these steps help. I was having AHCI problems on a clean install but turned out my F6 install disk I created was corrupt (after the Abit supplied Intel ICH7 disk had nforce drivers on). I considered installing XP under IDE and then following those steps later to activate AHCI, but chose to slipstream the correct drivers on my XP CD instead which worked like a charm.

Hi, you'll need to update the sata driver to ACHI before you change the bios otherwise windows cannot load the correct drivers, that's why it crashes.
