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: MODEM-CN CD-IN VGA PRINTER COM1 USB KB2 PS/2 MS IrDA JP28 I S A 1 P C I 3 P C I 2 P C I 1 A G P JP23 CPUFAN1 DIMM1 DIMM2 FAN1 WOL PWR2 BIOS IDE2 PANEL WOM JP14 IDE1 FDC DIMM3 2-2 Hardware Installation Jumpers: JP14: JP23: JP28: Clear CMOS AGP Ratio Enable/Disable KB/MS Wake Up Connectors: PS2: KB: COM1: COM2: PRINTER: PWR2: USB: FDC: IDE1: IDE2: CPUFAN1: FAN1: IrDA: PANEL: CD-IN: MODEM-CN: WOM: WOL: 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 CD-audio connector Mono in (Pin 1-2) and Mic out (Pin 3-4) Wake On Modem connector Wake On LAN connector 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 Celeron PPGA VID signal and SMbus clock generator provide CPU voltage auto-detection 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 jumperless 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 66.8, 75, 83.3, 100, 103, 112, 124/31, 124/41, 133/33, 133/44, , 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 = CPU Ratio * CPU FSB Intel Pentium II /Pentium III 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 CPU Core Frequency 233MHz = 266MHz = 300MHz = 333MHz = 350MHz= 400MHz= 450MHz= 450MHz = 500MHz = 550MHz = Ratio 3.5x 4x 4.5x 5x 3.5x 4x 4.5x 4.5x 5x 5.5x External Bus Clock 66MHz 66MHz 66MHz 66MHz 100MHz 100MHz 100MHz 100MHz 100MHz 100MHz INTEL Celeron CPU Core Frequency Ratio External Bus Clock 2-4 Hardware Installation INTEL Celeron Celeron 266 Celeron 300 Celeron 300A Celeron 333 Celeron 366 Celeron 400 Celeron 433 Celeron 466 CPU Core Frequency 266MHz = 300MHz = 300MHz = 333MHz = 366MHz = 400MHz = 433MHz = 466MHz = Ratio 4x 4.5x 4.5x 5x 5.5x 6x 6.5x 7x External Bus Clock 66MHz 66MHz 66MHz 66MHz 66MHz 66MHz 66MHz 66MHz Warning: INTEL 440ZX/BX chipset supports a maximum of 100MHz FSB, the higher clock settings are for internal test only. These settings exceed the specification of ZX/BX 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. 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 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. 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 over-clocking, please clear CMOS and the system will go back to the default setting (233MHz or 350MHz). Tip: If your system hangs or fails to boot because of over-clocking, simply use key to restore to the default setting. By this smart design, it would be more convenient to clear CPU frequency setting. For using this function, you just need to press key first and then press Power button at the same time. Note that do not release key until POST screen appearing. 2.2.4 KB/MS Wakeup JP28 1-2 2-3 KB/MS Wakeup Disabled Enabled This jumper is used to enable or disable Keyboard/Mouse Power ON function. If you select Enabled, you may decide the wakeup mode from BIOS Setup. To implement this function, the 5V Stand By current must be greater than 800mA. Note that only PS/2 mouse supports Wake On Mouse function. JP28 123 JP28 123 Disabled Enabled 2-6 Hardware Installation 2.2.5 AGP Ratio JP23 1-2 3-4 5-6 DC/Host Ratio Auto (default) 2/3 1/1 To improve system performance, this motherboard has implemented this jumper for setting the ratio of the display cache and CPU external frequency. 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 ZX/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 has a maximum of 100Mhz clock. 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.
