1.7
USB
The board supports up to eight USB 2.0 ports.
The port arrangement is as follows:
•
Four USB 2.0 ports are implemented with stacked back panel connectors
•
Four USB 2.0 front panel ports are implemented through two dual-port internal
headers
All eight 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.

1.8
SATA Interfaces
The board provides two 3.0 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 bus
resource steering is used.
Native mode is the preferred mode for configurations using
the Windows* XP, Windows Vista*, and Windows 7 operating systems.
