PCI Bus Master IDE Controller
• Two PCI IDE interfaces support up to four IDE devices
• Supports ATA/33, ATA/66, ATA/100 and ATA/133 hard drives
• UDMA Modes 3, 4, 5 and 6 Enhanced IDE (data transfer rate
up to 133MB/sec.)
• Bus mastering reduces CPU utilization during disk transfer
• Supports ATAPI CD-ROM, LS-120 and ZIP
Serial ATA IDE Interface
• Uses Marvell 88i8030 chip
• Supports one SATA (Serial ATA) interface which is compliant
with SATA 1.0 specification (1.5Gbps interface)
Serial ATA is a storage interface that is compliant with SATA 1.0
specification. With speed of up to 1.5Gbps, it improves hard drive
performance even in data intensive environments such as audio/
video, consumer electronics and entry-level servers.
IEEE 1394a Interface
• Uses VIA VT6306 chip
• Supports three 100/200/400 Mb/sec ports
The VIA VT6306 controller is a complete single chip IEEE 1394a
solution. It is fully compliant with the 1394a OHCI (Open Host
Controller Interface) 1.1 specification. 1394a 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 devices that need to transfer high levels of
data in real-time. 1394a suppor ts both Plug-and-Play and hot
plugging allowing devices to be attached or removed from the
system, even with the power on.
S/PDIF
The system board is equipped with the S/PDIF (Sony/Philips Digital
Interface) digital audio interface. S/PDIF is a standard audio file trans-
fer format that transfers 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.
