[. . . ] To clear the CMOS, follow the procedures as below: JP14 1 2 3 JP14 1 2 3 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. Tip: If your system hangs or fails to boot because of over-clocking, please clear CMOS and the system will go back to the default setting (233MHz or 350MHz). [. . . ] A higher setting may cause the system damage. 2-7 Hardware Installation 2. 3 Connectors 2. 3. 1 Power Cable The ATX power supply uses 20-pin connector shown below. 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.

PCB COM1 COM2 2. 3. 6 Printer The onboard printer connector is a 25-pin D-type connector marked PRINTER. The view angle of drawing shown here is from back panel of the housing. PRINTER PCB 2-10 Hardware Installation 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. 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 mainboard supports two 40 pin IDE connectors marked as IDE1 and IDE2. IDE1 is also known as primary channel and IDE2 as secondary channel, each channel supports two IDE devices that make total of four devices. In order to work together, the two devices on each channel must be set differently to master and slave mode, either one can be hard disk or CDROM. The setting as master or slave mode depends on the jumper on your IDE device, 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 2-11 Hardware Installation 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 Caution: The specification of IDE cable is maximum 46cm (18 inches), make sure your cable does not excess this length. Caution: For better signal quality, it is recommended to set far end side device to master mode and follow the suggested sequence to install your new device. Please refer to the following figure. IDE1 (Primary Channel) Slave (2nd) Master (1st) IDE2 (Second Channel) Slave (4th) Master (3rd) 2-12 Hardware Installation 2. 3. 10 Panel Connector The Panel (multifunction) connector is a 20-pin connector marked as PANEL on the board. Attach the power LED, keylock, speaker, SPWR, IDE LED and reset switch to the corresponding pins as shown in the figure. If your ATX housing supports ACPI specification, the ACPI & Power LED will keep flashing if you have enabled "suspend mode" item in the BIOS Setup. 1 GND KEYLOCK +5V IDE LED IDE LED +5V +5V GND NC SPEAKER 11 SPWR GND ACPI & POWER LED GND +5V NC NC GND RESET GND 10 20 PANEL 1 Keylock 11 + SPWR + IDE LED + ACPI & + + + Power LED Speaker Reset 10 20 PANEL 2-13 Hardware Installation 2. 3. 11 IrDA Connector The IrDA connector can be configured to support wireless infrared module, with this module and application software such as Laplink or Win95 Direct Cable Connection, the user can transfer files to or from laptops, notebooks, PDA devices and printers. This connector supports HPSIR (115. 2Kbps, 2 meters) and ASK-IR (56Kbps). Install the infrared module onto the IrDA connector and enable the infrared function from the BIOS setup, make sure to have the correct orientation when you plug in the IrDA connector.

[. . . ] 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. [. . . ]
