Serial ATA, HDD and Floppy Drive Connections

Note the following conditions when connecting the Serial ATA and hard disk drive
cables:
• Be sure to use the correct cable for each connector. Refer to Page 1-1 for cables
that came with your shipment.
• A red mark on a wire indicates the location of pin 1.
• The connector with twisted wires always connects to drive A, and the connector
that does not have twisted wires always connects to drive B.

SATA Connectors

Four Serial ATA (SATA) connectors (I-
SATA 0~3) are located on the mother-
board to provide serial link connections.
Serial Link connections provide faster
data transmission than those of the tra-
ditional Parallel ATA. These four SATA
connectors are supported by the Intel
ICH7 Chip (South Bridge). See the table
on the right for pin definitions.
