P4SP Motherboard
SATA1, SATA2: Serial ATA Drive Connectors
There are two Serial ATA connectors on the motherboard. Each connector supports one drive,
which connects to the motherboard with a Serial ATA cable. These two Serial ATA connectors
also support RAID 0 and RAID 1. The motherboard comes with two Serial ATA cables and one
power core for user’s convenience.
Serial ATA Interfaces
The ICH5’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. 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.
NOTE1: Many Serial ATA drives use new low-voltage power connectors and require adaptors or power supplies equipped
with low-voltage power connectors. For more information, see: http://www.serialata.org/
