Serial ATA Devices
The Serial ATA (Advanced Technology Attachment) is the standard interface for
the IDE hard drives, which is designed to overcome the design limitations while
enabling the storage interface to scale with the growing media rate demands of PC
platforms. It provides you a faster transfer rate of 150 MB/s. If you have
installed a Serial ATA hard drive, you can connect the Serial ATA cables to the
Serial ATA hard drive or the connector on the motherboard.
On the motherboard, locate the Serial ATA connectors SATA1-2, which support
new Serial ATA devices for the highest data transfer rates, simpler disk drive
cabling and easier PC assembly.
It eliminates limitations of the current Parallel ATA interface, but maintains
register compatibility and software compatibility with Parallel ATA.
Analog Audio Input Header
If you have installed a CD-ROM drive or DVD-ROM drive, you can connect
the drive audio cable to the onboard sound system.
When you first start up your system, the BIOS should automatically detect your
CD-ROM/DVD drive. If it doesn't, enter the Setup Utility and configure the
CD-ROM/DVD drive that you have installed. On the motherboard, locate the 4-
pin header CD_IN1.
