As I understand it, this is whats going on. People were getting p!ssed that they needed a floppy to load the SATA drivers while installing windows. What some motherboards do is map the SATA port to an IDE port. This makes the computer see the SATA port as a normal IDE port, and you don't need to load any SATA drivers. My motherboard came with this enabled by default, and I didn't need to mess with SATA drivers. Its up to you if you want to monkey with this.
I left it as an IDE port, and my machine is just fine. I have two IDE drives on the primary, and 2 DVD burners on the secondary. My boot drive is a SATA drive on SATA1, but is mapped to IDE3. (If I remember correctly, I think my bios believes I have 4 IDE ports.)
