Optimising SSD for windows 7?

Solution
1. Yes
2. The relevant port on the motherboard. Your manual will tell you which is which. Almost certainly SATA port 1.
3. Thats a setting in the BIOS
Usually, motherboards have both the default intel chip driving sata ports, but they also add an extra controller so as to add extra sata ports if the intel one doesn't have enough ports. So look in the manual to see which is which.

Look in the BIOS for AHCI, I don't know what mobo your using so that is all I can tell you.
