1.7.3.2 Serial ATA Interfaces
The ICH5-R’s Serial ATA controller offers two independent Serial ATA ports with a theoretical
maximum transfer rate of 150 MB/s per port. One device can be installed on each port for a
maximum of two Serial ATA devices. A point-to-point interface is used for host to device
connections, unlike Parallel IDE which supports a master/slave configuration and two devices per
channel.

connections, unlike Parallel 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 resource
steering is used. Native mode is the preferred mode for configurations using the Windows XP and
Windows 2000 operating systems.

Many Serial ATA drives use new low-voltage power connectors and require adaptors or power
supplies equipped with low-voltage power connectors.

1.7.3.3 Serial ATA RAID
The ICH5-R supports RAID (Redundant Array of Independent Drives) level 0 on the Serial ATA
ports. RAID 0 provides the ability to support striping. Two physical drives, of identical size, can
be teamed together to create one logical drive. As data is written or retrieved from the logical
drive, both drives operate in parallel, thus increasing the throughput.

The ICH5-R provides support for RAID O and RAID boot in Windows XP only.
1.7.3.4 RAID Boot Configuration Overview
A RAID array can be created by using the existing Serial ATA ports, correctly configuring the
BIOS, and installing drivers. The following steps are required to successfully establish a RAID
configuration.
