Have I bought this card because I wanted to connect my 4-Bay eSATA Fantec housing on my server. Unfortunately, the built-in motherboard ASUS P5E Deluxe supports the SATA port no port multiplier (PM). A RAID system so I have not built up, but the manual is intended for this type of use very well described. However, if you, like me, want all external panels have einzelnt available at one port, requires another controller BIOS. Considering that attention to the packaging of the controller on PM is, unfortunately, lacking any reference to the implementation of the manual. Simply download the manufacturing side (+ "/html/raid.shtml") and the appropriate file. Done.
