Installed the sil3132 drivers (non-raid) off their website and voila, works flawlessly in ML (GM). No KP's, not a single hiccup. When you plug the card it, it will show up without drivers installed. But when attaching esata device such as BlackXduet drive (dual HDD dock with esata) - nothing will show up, no esata devices attached will show up. You must install the drivers from the website then everything works as should. In fact, I have 4HDD's using the 2-blackXduet's connected to the two APIOTEK ports and the port multipliers work flawlessly. The card I have is an APIOTEK eSata II 3000 model express card adapter. Just FYI.
