From what I read on this thread, AHCI is the best setting for sata drives (I have no IDEs). Is there a way to install the AHCI drivers (F6 during XP install) without having a floppy drive?

And Vista already has the AHCI drivers, so there is no need to do anything special when installing Vista...correct?

OK...did some more extensive searching of the thread and found a few things of note...

Someone mentioned that Vista has the AHCI driver built-in, but it must be enabled (KB922976 - which oddly does not seem to exist anymore).

As for XP, does it matter wether or not you install the AHCI drivers during the install (via F6) or after (via device manager)?
