The onboard Realtek ALC850 which is an AC’97 com-
patible audio codec and the 6 audio jacks at the rear
I/O panel provides 8-channel audio output for advanced
7.1-channel super surround sound audio system.
ALC850 also supports S/PDIF input and output, allow-
ing digital connections with DVD systems or other audio/video mul-
timedia.
S/PDIF is a standard audio file transfer format that trans-
fers digital audio signals to a device without having to be
converted first to an analog format. This prevents the
quality of the audio signal from degrading whenever it is
converted to analog. S/PDIF is usually found on digital audio equip-
ment such as a DAT machine or audio processing device. The S/
PDIF connector on the system board sends surround sound and 3D
audio signal outputs to amplifiers and speakers and to digital re-
cording devices like CD recorders.
Serial ATA is a storage interface that is compliant with
SATA 1.0 specification. The system board supports 2 Serial
ATA ports with speed of up to 1.5Gb/s. Serial ATA im-
proves hard drive performance faster than the standard
parallel ATA whose data transfer rate is 100MB/s.
The Realtek RTL8110SB Gigabit Phy supports up to
1Gbps.
IEEE 1394 is fully compliant with the 1394 OHCI (Open
Host Controller Interface) 1.1 specification. It supports up
to 63 devices that can run simultaneously on a system.
1394 is a fast external bus standard that supports data
transfer rates of up to 400Mbps. In addition to its high speed, it
also supports isochronous data transfer which is ideal for video de-
vices that need to transfer high levels of data in real-time. 1394
supports both Plug-and-Play and hot plugging.
