6. Serial ATA connector (7-pin SATA1)
This next generation connector supports the thin Serial ATA cable for
a Serial ATA hard disk drive. The current Serial ATA interface allows
up to 150 MB/s data transfer rate, faster than the standard parallel
ATA with 133 MB/s (UltraATA133).
Important notes on Serial ATA
7. Serial port connector (10-1 pin COM1)
This connector supports the rear panel serial port.
• The Serial ATA cable is smaller and more flexible, allowing easier
routing inside the chassis. The lower pin count of the Serial ATA
cable eliminates the problem caused by the wide, flat ribbon cables
of the Parallel ATA interface.
• This motherboard does not support hot plug function for Serial ATA
drive and connections.
• Install Windows ® XP™ Service Pack 1 when using Serial ATA.
