You should have gotten a floppy disk with the motherboard, that has the necessary drivers to install Windows using SATA.
If you didn't, check MSI's website. I'm pretty sure they offer those things for download.
I just bought a MSI 865PE Neo3-F motherboard from newegg.
Here's the link http://www.newegg.com/app/ViewProductDesc.asp?description=13-130-481&depa=0
Problem is I can't get Windows XP setup to read the sata drive. I don't know which drivers I need to place on the diskette. I tried using the Intel IH5(R) drivers but it wouldn't pick up the sata drive.
Sata drive is a Samsung 120gb drive, S13C i think, I have the same drive installed on another computer and it works fine.
Someone please help?
