Installing the Motherboard
SATA1/2: Serial ATA connectors
These connectors are use to support the new Serial ATA devices for the highest date transfer
rates (1.5 Gb/s), 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.
IRDA1: Infrared header
The motherboard supports one Infrared (IRDA1) data port. Infrared port allows the
wireless exchange of information between your computer and similarly equipped devices
such as printers, laptops, Personal Digital Assistants (PDAs), and other computers.
AUX_IN1: Auxiliary In connector (optional)
This connector is an additional line-in audio connector. It allows you to attach a line-in
cable when your rear line-in jack is set as line out port for 4-channel function.
