I'll order up a spare drive & do some testing; I believe that all you need do is select AHCI in the BIOS, and then load the corresponding driver during the install, and that's it. My case has an eSATA port, & I did surgery on the eSATA bracket that was included to slice out the eSATA power port (which is really just a molex w/some mounting screws) to one of my blank drive plates in front, but I haven't yet had the occasion to try it out; I have got all four OSs, so I should be able to test in each. If you didn't install the driver(s) during the OS install, I know that's a problem, but it IS a soluble one - I'll try to do a search later today to find a good, clearly explained procedure for it...
