CN4 and CN5 Serial ATA Connectors

The Olympus III motherboard has two independent Serial ATA ports. Serial ATA has a
theoretical maximum transfer rate of 150 MBs per Serial ATA port. One Serial ATA
device can be installed on each Serial ATA port for a maximum of two Serial ATA
devices.
For compatibility, the underlying Serial ATA functionality is transparent to the operating
system. The Serial ATA controller can operate in both legacy and native Serial ATA
modes. In legacy mode, standard resources are assigned, such as IRQ 14 and IRQ 15. In
Native Serial ATA mode, standard PCI resource steering is used. Native Serial ATA
mode is recommended for use with the Microsoft® Windows XP and Microsoft®
Windows 2000/2003 operating systems.

or power supplies equipped with low-voltage power connectors. See serialata.org
