5) SATA2 0/1/2/3 (SATA 3Gb/s Connectors)
The SATA connectors conform to SATA 3Gb/s standard and are compatible with SATA 1.5Gb/s
standard. Each SATA connector supports a single SATA device. The AMD Chipset supports RAID 0,
RAID 1, RAID 10, and JBOD. Refer to Chapter 3, "Configuring SATA Hard Drive(s)," for instructions
on configuring a RAID array.

• A RAID 0 or RAID 1 configuration requires at least two hard drives. If more than two hard drives are to be
used, the total number of hard drives must be an even number.
• A RAID 10 configuration requires four hard drives.
• To enable hot-plugging for the SATA ports, refer to Chapter 2, "BIOS Setup," "Peripherals\SATA Configuration,"
for more information.
6) BAT (Battery)
The battery provides power to keep the values (such as BIOS configurations, date, and time information)
in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low
level, or the CMOS values may not be accurate or may be lost.
You may clear the CMOS values by removing the battery:
1. Turn off your computer and unplug the power cord.
2. Gently remove the battery from the battery holder and wait for one minute. (Or use a metal
3. Replace the battery.
4. Plug in the power cord and restart your computer.
• Always turn off your computer and unplug the power cord before replacing the battery.
• Replace the battery with an equivalent one. Danger of explosion if the battery is replaced with an incorrect model.
• Contact the place of purchase or local dealer if you are not able to replace the battery by yourself or uncertain
about the battery model.
• When installing the battery, note the orientation of the positive side (+) and the negative side (-) of the battery
(the positive side should face up).
• Used batteries must be handled in accordance with local environmental regulations.
7) CLR_CMOS (Clear CMOS Jumper)
Use this jumper to clear the BIOS configuration and reset the CMOS values to factory defaults. To clear
the CMOS values, use a metal object like a screwdriver to touch the two pins for a few seconds.
Open: Normal
Short: Clear CMOS Values
• Always turn off your computer before clearing the CMOS values.
• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or manually
configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS configurations).
