Chapter 2 Hardware Installation This chapter gives you a step-by-step procedure on how to install your system. Follow each section accordingly. Caution: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components. Always observe the following precautions before you install a system component. 1. Do not remove a component from its protective packaging until you are ready to install it. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a component. If a wrist strap is not available, maintain contact with the system unit throughout any procedure requiring ESD protection. 2. 2-1 Hardware Installation 2.1 Jumper and Connector Locations The following figure shows the locations of the jumpers and connectors on the system board: IrDA JP14 BIOS COM2 FDC COM1 USB KB PS/2 I S A 2 I S A 1 PRINTER P C I 5 P C I 4 P C I 3 P C I 2 P C I 1 A G P CPU SLOT 1 JP28 CPU FAN S -L k B in DIMM1 DIMM2 DIMM3 Modem-WKUP JP23 FAN IDE2 PANEL PWR2 L N aep AW u k IDE1 2-2 Hardware Installation Jumpers: JP14: JP23: JP28: Clear CMOS AGP Ratio Keyboard/Mouse Wake Up Connectors: PS2: KB: COM1: COM2: PRINTER: PWR2: USB: FDC: IDE1: IDE2: CPUFAN: FAN: IrDA: PANEL: WOM: WOL: SB-LINK: PS/2 mouse connector PS/2 keyboard connector COM1 connector COM2 connector Printer connector ATX power connector USB connector Floppy drive connector IDE1 primary channel IDE2 secondary channel CPU Fan connector Housing Fan connector IrDA (Infrared) connector Front panel (Multifunction) connector Wake On Modem connector Wake On LAN connector Sound Blaster Link connector Warning: This motherboard supports 4 PCI master card, so you can only install PCI slave card on PCI 5, for example, a PCI VGA card. 2-3 Hardware Installation 2.2 Jumpers With the help of Pentium II / Pentium III / Celeron VID signal and SMbus, this motherboard is jumper-less design. 2.2.1 Selecting the CPU Frequency Pentium II / Pentium III / Celeron VID signal and the SMbus clock generator provide CPU voltage auto-detection and allow the user to set CPU frequency through the CMOS setup, no jumpers or switches are needed. The correct CPU information is saved into the EEPROM. With these technologies, the disadvantages of the Pentium based jumper-less design are eliminated. There will be no worry of wrong CPU voltage detection and no need to re-open the housing if the CMOS battery is lost. The CPU frequency selection is set by going into: BOIS Setup à Chipset Features Setup à CPU Clock Frequency (The possible setting is 66.8, 68.5, 75, 83.3, 100, 103, 112, 117, 124, 129, 133.3, 138, 143, 148 and 153 MHz) BOIS Setup à Chipset Features Setup à CPU Clock Ratio (The possible setting is 1.5x, 2x, 2.5x, 3x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x, and 8x) Core frequency = Ratio * External bus clock INTEL Pentium II Pentium II - 233 Pentium II - 266 Pentium II - 300 Pentium II - 333 Pentium II - 350 Pentium II - 400 Pentium II - 450 Pentium III - 450 Pentium III - 500 Pentium III - 550 Celeron 266 Celeron 300 Celeron 300A CPU Core Frequency 233MHz = 266MHz = 300MHz = 333MHz = 350MHz = 400MHz = 450MHz = 450MHz = 500MHz = 550MHz = 266MHz = 300MHz = 300MHz = Ratio 3.5x 4x 4.5x 5x 3.5x 4x 4.5x 4.5x 5x 5.5x 4x 4.5x 4.5x External Bus Clock 66MHz 66MHz 66MHz 66MHz 100MHz 100MHz 100MHz 100MHz 100MHz 100MHz 66MHz 66MHz 66MHz 2-4 Hardware Installation INTEL Pentium II Celeron 333 Celeron 366 Celeron 400 Celeron 433 Celeron 466 CPU Core Frequency 333MHz = 366MHz = 400MHz = 433MHz = 466MHz = Ratio 5x 5.5x 6x 6.5x 7x External Bus Clock 66MHz 66MHz 66MHz 66MHz 66MHz Warning: The INTEL 440ZX chipset supports a maximum of 100MHz FSB clock, the higher clock settings are for internal test only. These settings exceed the specification of the ZX chipset, which may cause serious system damage. 2.2.2 Setting the CPU Voltage This motherboard supports Pentium II / Pentium III / Celeron VID function, the CPU core voltage is automatically detected, the range is from 1.3V to 3.5V. 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. 2. 3. 4. 5. 6. 7. Turn off the system and unplug the AC power. Remove ATX power cable from connector PWR2. Locate JP14 and short pins 2-3 for a few seconds. Return JP14 to its normal setting by shorting pins 1-2. Connect ATX power cable back to connector PWR2. Turn on the system power. 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 overclocking, please clear the CMOS and the system will go back to its default setting (233MHz). Tip: If your system hangs or fails to boot because of overclocking, simply use the key to restore the default setting (233MHz). By this smart design, it would be more convenient to clear CPU frequency setting. For using this function, you just need to press the key first and then press the Power button at the same time. Note: do not release the key until the POST screen appears. 2-6 Hardware Installation 2.2.4 AGP Ratio JP23 1-2 3-4 5-6 AGP Ratio Auto (default) 2/3 1/1 To improve system performance, AX6BC Pro has implemented this jumper for AGP to synchronize the CPU 100Mhz (or above) external frequency. We recommend choosing a better AGP card for overclocking. Some AGP cards can not take 100MHz bus frequency and may cause overclocking failure. JP23 246 JP23 246 JP23 246 135 135 135 Auto (Default) 2/3 1/1 There is a "66/100" signal pin from CPU for ZX chipset to automatically identify AGP clock, this is important for jumperless design. When a 66MHz Pentium II CPU is used, the north bridge will synchronize the CPU external frequency and the AGP bus frequency. Therefore, when you set the CPU external frequency to 100MHz, the AGP bus will also runs at 100MHz. With 100MHz Pentium II CPU, the north bridge automatically set AGP frequency to 2/3 AGP frequency. In other words, the AGP card will still runs at 66MHz while the CPU is running at 100MHz external frequency. Except Auto setting, you may also set this jumper to 2/3 or 1/1. Below is a table for better understanding: CPU Type 66MHz 66MHz 66MHz 100MHz 100MHz 100MHz 100MHz 100MHz 100MHz 66/100 signal Low Low Low High High High High High High Bus clock 66MHz 100MHz 100MHz 100MHz 100MHz 100MHz 133MHz 133MHz 133MHz AGP clock 66MHz 100MHz 66MHz 66MHz 66MHz 100MHz 88.6MHz 88.6MHz 133MHz JP23 1-2 1-2 3-4 1-2 3-4 5-6 1-2 3-4 5-6 Warning: The specification of AGP is maximum 66Mhz clock. If the bus clock is larger than 66MHz, setting this 2-7 Hardware Installation item to Enabled may cause serious system damage. 2.2.5 KB/MS WKUP JP28 1-2 2-3 KB/MS WKUP Disabled Enabled This jumper is used to enable or disable the Keyboard/Mouse Power ON function. 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. Note that only PS/2 mouse supports the Wake On Mouse function.

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. Either one can be the hard disk or the CDROM. 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.
