Product Description

1.6.3 USB

The board supports up to 12 USB 2.0 ports, supports UHCI and EHCI, and uses UHCI-

and EHCI-compatible drivers.

The ICH10R provides the USB controller for all ports. The port arrangement is as

follows:

• Six ports are implemented with stacked back panel connectors

• Six ports are routed to three separate front panel USB headers

For information about Refer to

The location of the USB connectors on the back panel Figure 9, page 45

1.6.4 Serial ATA Interfaces

The board provides five Serial ATA (SATA) connectors, which support one device per

connector. The board also provides one red-colored external Serial ATA (eSATA)

connector on the back panel.

1.6.4.1 Serial ATA Support

The board’s Serial ATA controller offers six independent Serial ATA ports with a

theoretical maximum transfer rate of 3 Gbits/sec per port. One device can be installed

on each port for a maximum of six Serial ATA devices. A point-to-point interface is

used for host to device connections, unlike Parallel ATA IDE which supports a

master/slave configuration and two devices per channel.

For compatibility, the underlying Serial ATA functionality is transparent to the

operating system. The Serial ATA 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 and

Windows Vista operating systems.

NOTE

Many Serial ATA drives use new low-voltage power connectors and require adapters or

power supplies equipped with low-voltage power connectors.
