Connect the hard drives to the connectors
labeled "SATA0" and "SATA1", starting with
SATA0. Connect CD/DVD drives to the connectors labeled
"SATA2","SATA3", or "SATA4", starting with "SATA2".
Serial ATA hard drives and CD/DVD drives are
connected to the connectors labeled "SATA0" to "SATA4" on the system board.
NOTE: It is recommended that you connect the hard
drive to the connector labeled SATA0 on the system board. Connect additional
hard drives to connectors labelled SATA1 and SATA2.
When
you restart your computer, enter system setup (see
System Setup). Then, go to the "Drives" section of the BIOS and under
SATA 0 through 4,
set the SATA port to "ON"
for the hard drive you just installed. This enables the drive.
