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 A55 Chipset supports RAID 0, RAID 1,
RAID 10, and JBOD. Refer to Chapter 3, "Conguring SATA Hard Drive(s)," for instructions on conguring
a RAID array.

• A RAID 0 or RAID 1 conguration 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 conguration requires four hard drives.
6) BAT (Battery)
The battery provides power to keep the values (such as BIOS congurations, 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
object like a screwdriver to touch the positive and negative terminals of the battery holder,
making them short for 5 seconds.)
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 conguration 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.
• Always turn off your computer and unplug the power cord from the power outlet before clearing the CMOS values.
• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or manually
congure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS congurations).
