2-9 Serial ATA and HDD 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-SA-
TA 0~3) are located on the motherboard
to provide serial link connections. Se-
rial Link connections provide faster data
transmission than those of the traditional
Parallel ATA. These four SATA connec-
tors are supported by the Intel ICH7R
South Bridge. See the table on the right
for pin denitions.
