I am in the same situation.
I have been using an extra PCI Card before this board, and among the better ones I have used in the past, is my ITE8212 IDE Card. Its a non-bootable one, which is what I want, and it allows me to use anythign in it, while a lot of them only seem to want HDs, this one can play with anything.
SATA I or SATA II
The Orange connections ( There are 4 ) are SATA 1 and the Purple ones are SATA II ( Correct me if Im wrong on that one )
The SATA II ( Purple ones ) can act as IDE or RAID and these are the other 2 that are shared with the normal IDE port
AFAIK you can use SATA 1 or 2 in any of the ports
