Hardware Setup 2.3.1 CMOS Memory Clearing Header and Backup Battery The time to clear the CMOS memory occurs when (a) the CMOS data becomes corrupted, (b) you forgot the supervisor or user password preset in the BIOS menu, (c) you are unable to boot-up the system because the CPU ratio/clock was incorrectly set in the BIOS menu. This header uses a jumper cap to clear the CMOS memory and have it reconfigured to the default values stored in BIOS. Pins 1 and 2 shorted (default): Normal o

CMOS Backup Battery: An onboard battery saves the CMOS memory to keep the BIOS information stays on even after disconnected your system with power source. Nevertheless, this backup battery exhausts after some five years. Once the error message like “CMOS BATTERY HAS FAILED” or “CMOS checksum error” displays on monitor, this backup battery is no longer functional and has to be renewed. To renew the backup battery: 1. Power off the system and disconnect with AC power source. 2. Re

2.4 Connecting Chassis Components 2.4.1 ATX Power Connectors These connectors provide the connection from an ATX power supply. As the plugs from the power supply fit in only one orientation, find the correct one and push firmly down into these connectors. ATX 24-Pin Power Connector: The power supply with 20-pin or 24-pin cables can both be connected to this 24-pin connector. Connect from pin-1 for either type. However, a 20-pin power supply may cause the system unstable or even un

Hardware Setup 2.4.2 Front Panel Switches & Indicators Headers This header is used for connecting switches and LED indicators on the chassis front panel. Watch the power LED pin position and orientation. The mark “+” align to the pin in the figure below stands for positive polarity for the LED connection. Please pay attention when connecting these headers. A wrong orientation will only cause the LED not lighting, but a wrong connection of the switches could cause system malfunction.

Hardware Setup 2.5.2 DDR2 Memory Slots This motherboard provides four 240-pin DIMM slots for Dual Channel DDR2 800 memory modules with memory expansion size up to 8GB. To reach the performance of Dual Channel DDR2, the following rules must be obeyed: For a 2-DIMM dual-channel installation: Populate DIMM modules of the same type and size on slots [DIMM1]+[DIMM2], or slots [DIMM3]+[DIMM4]. For a 4-DIMM dual-channel installation: Populate 2 DIMM modules of the same type and siz
