Well, I have that board - and its a dream.
I am assuming you are trying to install XP on it, but I need more information.
If you are, you need the floppy that came with it for the SATA/SCSI drivers for the mobo. When you start the XP Install CD you have to hit F6, and put the floppy in, and follow the prompts of loading SATA drivers.
And btw, for me it doesn't matter which SATA connector I am using.
