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 BIOS COM2 COM1 I S A 3 I S A 2 I S A 1 USB KB PS/2 P C I 4 P C I 3 P C I 2 P C I 1 A G P FDC PRINTER JP14 PWR2 CPU SLOT 1 R A I D P O R T HDD LED SB-Link CPU FAN DIMM4 DIMM3 DIMM2 DIMM1 SPWR IDE2 LAN Wakeup IDE1 WKUP PANEL 1 FAN SCSI Wide-SCSI JP23 2-2 Hardware Installation Jumpers: JP14: JP23: Clear CMOS AGP Ratio Connectors: PS2: KB: COM1: COM2: PRINTER: PWR2: USB: FDC: IDE1: IDE2: CPUFAN: FAN: IrDA: HDD LED: PANEL: SPWR: MODEM-WKUP: LAN-WKUP: 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 HDD LED connector Front panel (Multifunction) connector ATX Soft-Power Switch Connector Modem Wake Up Connector LAN Wake Up Connector Creative PCI sound card connector 2-3 Hardware Installation 2.2 Jumpers With the help of Pentium II VID signal and SMbus, this motherboard is jumperless design. 2.2.1 Selecting the CPU Frequency Pentium II VID signal and SMbus clock generator provide CPU voltage autodetection and allow user to set CPU frequency through CMOS setup, no jumper or switch is needed. The correct CPU information is saved into EEPROM, with these technologies, the disadvantages of Pentium base jumper-less design are eliminated. There will be no worry of wrong CPU voltage detection and no need to re-open the housing if CMOS battery loss. The CPU frequency selection is set by going into: BOIS Setup à Chipset Features Setup à CPU Clock Frequency (The possible setting is 66, 68.5, 75, 83.3, 100, 103, 112 and 133.3 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 Celeron 266 Celeron 300 Celeron 300A Celeron 333 CPU Core Frequency 233MHz = 266MHz = 300MHz = 333MHz = 350MHz= 400MHz= 450MHz= 266MHz= 300MHz 300MHz 333MHz Ratio 3.5x 4x 4.5x 5x 3.5x 4x 4.5x 4x 4.5x 4.5x 5x External Bus Clock 66MHz 66MHz 66MHz 66MHz 100MHz 100MHz 100MHz 66MHz 66MHz 66MHz 66MHz 2-4 Hardware Installation Warning: INTEL 440BX chipset supports maximum 100MHz external CPU bus clock, the 103, 112 and 133.3MHz are for internal test only. These settings exceed the specification of BX chipset, which may cause serious system damage. 2.2.2 Setting the CPU Voltage This motherboard supports Pentium II VID function, the CPU core voltage is automatically detected, the range is from 1.3V to 3.5V. 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 procedures listed below: JP14 1 2 3 JP14 1 2 3 Normal Operation (default) 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. Clear CMOS 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 default setting (233MHz). 2-5 Hardware Installation Tip: Except using JP14, you may also press key. By this smart design, it would be more convenient to clear CMOS. For using this function, you just need to press key first and then press Power button at the same time. After doing this, the system will return to the default setting (233MHz). 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, AX6B has implemented this jumper for AGP to synchronize the CPU 100Mhz (or above) external frequency. We recommend you choose a better AGP card for overclocking. Some AGP cards can not take 100MHz bus frequency and may cause overclocking failure. JP23 1 3 5 2 4 6 1 3 5 JP23 2 4 6 1 3 5 JP23 2 4 6 Auto (Default) 2/3 1/1 There is a "66/100" signal pin from CPU for BX 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 item to Enabled may cause serious system damage. 2-7 Hardware Installation 2.3 Connectors 2.3.1 Power Cable The ATX power supply uses 20-pin connector shown below.

IDE1 is also known as primary channel and IDE2 as secondary channel, each channel supports two IDE devices that makes 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 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 IDE cable is maximum 46cm (18 inches), make sure your cable does not excess this length.
