12. Digital Audio connector (4-1 pin SPDIF_OUT1)
In addition to the S/PDIF out port on the rear panel, an S/PDIF Out
connector is available for an S/PDIF audio module. Connect one end
of the S/PDIF audio cable to this connector and the other end to the
S/PDIF module.
11. Serial ATA connectors (7-pin SATA1, SATA2)
These next generation connectors support the thin Serial ATA cables
for primary internal storage devices. The current Serial ATA interface
allows up to 150 MB/s data transfer rate, faster than the standard
parallel ATA with 133 MB/s (Ultra ATA/133).
The S/PDIF out module is purchased separately.
