1.8  USB 
The board supports up to six USB 2.0 ports. The port arrangement is as follows: 
•  Four USB 2.0 ports are implemented with stacked back panel connectors (black) 
•  Two USB 2.0 front panel ports are implemented through one dual-port internal 
header 
All six USB ports are high-speed, full-speed, and low-speed capable.  
 
NOTE 
Computer systems that have an unshielded cable attached to a USB port may not meet 
FCC Class B requirements, even if no device is attached to the cable.  Use a shielded 
cable that meets the requirements for full-speed devices.

1.9  SATA Interfaces 
The board provides four 3 Gb/s SATA connectors, which support one device per 
connector. 
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.
