The board supports up to twelve USB 2.0 ports through two EHCI host controllers on 
the PCH that allow the use of EHCI-compatible drivers.   

The port arrangement is as follows: 
•  Six ports are implemented with stacked back panel connectors 
•  Six front panel ports are implemented with three dual-port internal headers

The board provides four internal SATA connectors (black) and one external SATA 
connector through the PCH, which support one device per connector. 

The PCH provides independent SATA ports with a theoretical maximum transfer rate of 
3 Gb/s per port.  A point-to-point interface is used for host to device connections, 
unlike Parallel ATA (PATA) IDE which supports a master/slave configuration and two 
devices per channel. 

The underlying SATA functionality is transparent to the operating system.  The SATA 
controller can operate in both legacy and native modes.  In legacy mode, standard IDE 
I/O and IRQ resources are assigned (IRQ 14 and 15).  In Native mode, standard PCI 
Conventional bus resource steering is used.  Native mode is the preferred mode for 
configurations using the Windows* XP, Windows Vista*, and Windows 7* operating 
systems.
