The board includes a discrete Marvell 88E6145 SATA controller that provides two
internal SATA ports (blue) and one eSATA port (red) on the back panel.
The red eSATA connector on the back panel can be used to connect an eSATA drive. It
can also be used for port replication, which allows the aggregation of multiple hard
drives on the eSATA port. Figure 10 on page 42 shows the location of the External
SATA -compatible SATA ports on the back panel.
The Marvell 88E6145 controller uses the PCI Express bus for data transfer with a
theoretical maximum transfer rate of 3 Gb/s per port. These connectors are in
addition to the six SATA connectors of the PCH SATA interface.
To use the eSATA ports you must enable RAID support in the BIOS for the Marvell
discrete controller. The two internal ports can stay in the default IDE mode if RAID is
not required.
The discrete SATA interface supports the following RAID levels:

NOTE
The Marvell 88E6145 controller supports single drive non-RAID configurations as well
as RAID configurations. For RAID configurations, you must install the RAID drivers by
pressing F6 during operating system installation. See your operating system
installation documentation for more information about installing drivers during the
installation process.
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When
the computer is not plugged into a wall socket, the battery has an estimated life of
three years. When the computer is plugged in, the standby current from the power
supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at
25 ºC with 3.3 VSB applied via the power supply 5V STBY rail.
NOTE
If the battery and AC power fail date and time values will be reset and the user will be
notified during POST.
When the voltage drops below a certain level, the BIOS Setup program settings stored
in CMOS RAM (for example, the date and time) might not be accurate. Replace the
battery with an equivalent one. Figure 1 on page 11 shows the location of the battery.
