normal Sata operation does not require a separate driver.
It might also depend on BIOS and on controller itself (part of OS setrup), however in 99 % of cases you must load from floppy SATA drivers first during OS installation.
F8 / F6 / S / Enter and repeat as needed ( " S & "ENTER" to load all the drivers ) !
Yes, I had one installation where the WIN XP SP installed without SATA drivers for nForce 4, but I couldn't use that pc as I wanted.
Try to load Windows 2000, or Windows XP without service pack 2 and come back wih the results and please post them here.
I have performed over 1,111 OS installation and
always needed to load SATA/RAID drivers from the floppy made using MoBo CD.
Please READ the MANUAL!
If SATA / RAID drivers are not loaded OS / BIOS will NOT recognize the SATA drive during windows 2000/XP installation.
This gould change with XP SP 2, but I am not certain at this time, as I am installing drivers religiously based on my past experience.
