[. . . ] For overclocking, the CPU voltage also can be adjusted in the BIOS Setup. The CPU voltage is adjustable by going into: Chipset Features à CPU Voltage Set to However, note that enlarging the core voltage is probably harmful to your CPU. 2. 2. 3 Clearing the CMOS JP14 1-2 2-3 Clear CMOS Normal operation (default) Clear CMOS You need to clear the CMOS if you forget your system password. To clear the CMOS, follow the procedure below: JP14 123 JP14 123 Normal Operation (default) Clear CMOS 2-5 Hardware Installation The procedure to clear CMOS: 1. Press during bootup to enter the BIOS Setup Utility and specify a new password, if needed. [. . . ] If you select Enabled, you may choose the wakeup mode from the BIOS Setup. To implement this function, the 5V Stand By current must be greater than 800mA.

Caution: Make sure that the power supply is off before connecting or disconnecting the power cable. +5V 3. 3V 5V SB 3. 3V +5V PWR2 2. 3. 2 Fan Plug in the fan cable to the 3-pin fan connector onboard. The fan connector is marked CPUFAN1 and FAN1 on the system board. GND +12V SENSE CPUFAN1 FAN1 Note: Attach the fan cable to either the CPU FAN connector or the FAN connector. Both of these two fan connectors can support the hardware monitoring function. However, you can only use the CPU FAN connector to control the fan power ON/OFF. 2-9 Hardware Installation 2. 3. 3 PS/2 Mouse The onboard PS/2 mouse connector is a 6-pin Mini-Din connector marked PS2. The view angle of drawing shown here is from the back panel of the housing. PCB PS/2 Mouse 2. 3. 4 Keyboard The onboard PS/2 keyboard connector is a 6-pin Mini-Din connector marked KB2. The view angle of drawing shown here is from the back panel of the housing. PCB PS/2 KB 2. 3. 5 Serial Devices (COM1/COM2) The onboard serial connectors are 9-pin D-type connectors on the back panel of motherboard. The serial port 1 connector is marked as COM1 and the serial port 2 connector is marked as COM2. PCB COM1 COM2 2-10 Hardware Installation 2. 3. 6 Printer The onboard printer connector is a 25-pin D-type connector marked PRINTER. The view angle of the drawing shown here is from the back panel of the housing. PRINTER PCB 2. 3. 7 USB Device You can attach USB devices to the USB connector. The motherboard contains two USB connectors, which are marked as USB. PCB USB 2-11 Hardware Installation 2. 3. 8 Floppy Drive Connect the 34-pin floppy drive cable to the floppy drive connector marked as FDC on the system board. 2 1 34 33 FDC 2. 3. 9 IDE Hard Disk and CD ROM This motherboard supports two 40 pin IDE connectors marked as IDE1 and IDE2. IDE1 is also known as the primary channel and IDE2 as the secondary channel. Each channel supports two IDE devices that make a total of four devices. In order to work together, the two devices on each channel must be set differently to master and slave mode. The setting as master or slave mode depends on the jumper on your IDE device, so please refer to your hard disk and CDROM manual accordingly. Connect your first IDE hard disk to master mode of the primary channel. If you have second IDE device to install in your system, connect it as slave mode on the same channel, and the third and fourth device can be connected on secondary channel as master and slave mode respectively. 2 1 40 39 IDE2 2 1 40 39 IDE1 2-12 Hardware Installation Caution: The specification of the IDE cable is a maximum of 46cm (18 inches), make sure your cable does not exceed this length. Caution: For better signal quality, it is recommended to set the far end side device to master mode and follow the suggested sequence to install your new device. Please refer to the following figure. IDE2 (Secondary Channel) Slave (4th) Master (3rd) IDE1 (Primary Channel) Slave (2nd) Master (1st) 2. 3. 10 Panel Connector The Panel (multifunction) connector is a 20-pin connector marked as PANEL on the board. [. . . ] Tip: To identify 2-clock and 4-clock SDRAM, you may check if there are traces connected to the golden finger pins 79 and 163 of the SDRAM. If there are traces, the SDRAM is probably 4-clock; Otherwise, it is 2-clock. Parity: This motherboard supports standard 64 bit wide (without parity) DIMM modules. SPD support: The BIOS will automatically detect DIMMs with SPD, and set to the appropriate timing. [. . . ]
