1.8 USB
The board supports up to 12 USB 2.0 ports. The Intel B65 Express Chipset provides
the USB controller for the 2.0 ports. The port arrangement is as follows:
• Six USB 2.0 ports are implemented with stacked back panel connectors
• Six USB 2.0 front panel ports implemented through three internal headers
All 12 USB ports are high-speed, full-speed, and low-speed capable.
NOTES
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 six SATA connectors through the PCH, which support one device
per connector:
• One internal SATA 6 Gb/s port (blue)
• Three internal SATA 3 Gb/s ports (black)
• Two internal eSATA 3 Gb/s ports for external connectivity (red)
The PCH provides independent SATA ports with a theoretical maximum transfer rate of
6 Gb/s for one port and 3 Gb/s for five ports. A point-to-point interface is used for
host to device connections.
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.
