Be sure to disconnect the power cable from the power source before performing any work on your mainboard, i. e. installing a CPU, memory module, changing a jumper setting, etc. Not doing so may result in electrical shock! 2-1 Introduction to Jumpers Jumpers are used to select between various operating modes. A jumper consists of a row of gold colored pins that protrude from the surface of the mainboard. It is important not to confuse jumpers with connectors or headers. Putting jumper caps on anything that is not a jumper may result in damaging your mainboard. Please refer to Section 1-3, Mainboard Layout, for the location of jumpers on your mainboard. As indicated in Figure 2-1 below, a cap is used to cover the pins of a jumper, resulting in shorting those pins that it covers. If the cap is removed from the top of the pins, the jumper is left "open." The number 1 shown both in the diagram below and in all multiple pin jumper and header diagrams in this manual indicates the pin designated with the number 1. The numbering of the remaining pins follows in sequence. Pins Cap Setting Cap Style 2 1 A 3-pin jumper 1 A cap over pin 1 and pin 2 shorts these pins Figure 2-1 7 7ata0-2.p65 7 2000/3/31, PM 01:11 Chapter 2 2-2 Installing an AMD Athlon Processor in Slot A 1. Insert the AMD Athlon processor into the retention mechanism. Press evenly and gently until the snaps on the upper side of the processor have been inserted into the holes at the top of the retention mechanism. 2. Note that when removing the processor, these snaps should be clicked into a completely vertical position, leaving your hands free to stabilize the board. Pull the processor evenly and gently out of the retention mechanism. 3. Also note that like PCI and ISA slots, Slot 1 has a divider that prevents backwards insertion of the CPU. Installing a heat sink with cooling fan is necessary for proper heat dissipation from your CPU. Failing to install these items may result in overheating and possible burnout of your CPU. 2-3 Plug and Play CPU Configuration This board support plug and play CPU configuration, if you install a CPU on this mainboard, the board will automatically detect and set the CPU system bus frequency speed. It is no longer necessary to make many jumper settings as on conventional mainboards. CPU Host/PCI Clock Timing 1. After installing all your hardware into your PC system, turn on your system's power. Enter the CMOS Setup Utility by pressing the Delete key when your BIOS identification screen appears. 2. Move the cursor to Frequency/Voltage Control Setup menu and press Enter. Select the CPU Host/PCI Clock Setup commands at the left hand side of the BIOS screen. 3. Select the CPU Host/PCI Clock value according to the speed of your CPU processor and PCI bus. (See section 3-8) 4. Press Esc to return to the CMOS Setup Utility, press F10 to Save and Exit Setup and choose to confirm. The system will automatically reboot and during start-up you will see the correct CPU type shown on the screen. You do not need to make frequency ratio and voltage settings because this board will automatically sets your CPU frequency ratio & voltage. 8 7ata0-2.p65 8 2000/3/31, PM 01:11 Hardware Setup JP1, J1, J5 J2, J3, JP4 JP2/3, JP4 FAN1 CN5, CN6, FAN2 JP5, JP7, JP8 Jumper & Connector No. JP1 JP2/JP3 JP4 JP5 JP7 JP8 J1 J2 J3 J4 J5 CN1 CN2 Onboard Audio select Function Page 13 13 13 14 14 14 15 15 15 16 16 16 16 11 11 12 12 12 12 12 17 10 17 Audio line out or speaker out Primary Audio CODEC select Boot BIOS select (Optional) Clear CMOS data jumper Chassis Intrusion Detection CD-ROM audio in connector Audio Mono-in/out connector AUX audio in connector Infrared / Consumer Infrared connector USB 2/3 connector PS/2 mouse and keyboard ports USB 0/1ports Over-ride power button connector Power indicator LED connector Green switch / Green LED connector CN5 System reset switch connector Speaker connector IDE activity LED connector Turbo LED connector CN6 PW1 FAN1/2 WOL(Wake On LAN) connector ATX Power supply connector CPU/ System cooling fan connector 9 7ata0-2.p65 9 2000/3/31, PM 01:12 Chapter 2 2-4 Connector and Jumper Settings Connectors are used to link the system board with other parts of the system, including the power supply, the keyboard, and the various controllers on the front panel of the system case. The power supply connector is the last connection to be made while installing a mainboard. Before connecting the power supply, please make sure it is not connected to the power source. ATX Power Supply Connector (PW1) The power cord leading from the system's power supply to the external power source must be the very last part connected when assembling a system. The ATX power supply provides a single 20-pin connector interface which incorporates standard +/ -5V, +/-12V, optional 3.3V and Soft-power signals. The Soft-power signal, a 5V trickle supply is continuously supplied when AC power is available. When the system is in the Soft-Off mode, this trickle supply maintains the system in it's minimum power state. Software Power-Off Control This mainboard can be powered down using the Windows 95/98 Software Power-Off function. To power down your computer, click the START button on the Windows 95 task bar. Select "Shut Down The Computer" and the system turns off. The message "It is now safe to turn off your computer" will not be shown when using this function. Power-On By Modem While in Soft-off state, if an external modem ring-up signal occurs, the system wakes up and can be remotely accessed. You may enable this function in BIOS's Power Management Setup menu. (See section 3-4) 10 7ata0-2.p65 10 2000/3/31, PM 01:12 Hardware Setup Front Panel Connector Set (CN5) A through G A. Over-ride Power Button Connector The power button on the ATX chassis can be used as a normal power switch as well as a device to activate Advanced Power Management Suspend mode. This mode is used for saving electricity when the computer is not in use for long periods of time. The Soft-OFF by PWR-BTTN function in BIOS's Power Management Setup menu must be set to "Delay 4 Sec." to activate this function. (See section 3-5) When the Soft-OFF by PWR-BTTN function is enabled, pushing the power button rapidly will switch the system to Suspend mode. Any occurrence of external activities such as pres ...
