[. . . ] 1 Electronic Emission Notices Federal Communications Commission (FCC) Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with instructions contained in this manual, may cause harmful interference to radio and television communications. However, there is no guarantee that interference will not occur in a particular installation. [. . . ] Before using your computer, make sure all jumpers and DRAM modules are set correctly. Refer to this chapter whenever in doubt. 1 1 1 1 2 1 1 JP34 JP33 JP8 JP29 1 JP20 1 JP1 1 CPU Speed Selection When JP7 is installed on this motherboard, jumper is required to be set for different type of CPU installed. The CPU speed is set by JP1, JP2, and JP7, please see JP7- Ratio of Processor Core to System Bus Frequency table. When JP7 is not installed on this motherboard, jumperless feature is implemented such that no jumper is required to be set for different type of CPU installed. The CPU speed is set in "CPU Speed Setting" of CMOS Setup. Be sure to save the CMOS setting when exit the CMOS. When System Bus Frequency is 100MHz, DIMM RAM must be PC100 stanard. When the system is turned on the first time or the CPU is changed, a Pentium II-133 or -200 (depends on the CPU bus speed) will be recognized and a warning message of "CPU has been changed" will appear. Please enter the CMOS setup menu to configure the CPU speed.

Hardware Configuration 8 Keyboard Password Power On This motherboard provides a special security feature of keyboard password power on. The feature is enabled in Integrated Peripherals Menu of CMOS setup. Insert the processor in the retention mechanism. Press down on the processor until it is firmly seated in the Slot 1 connector. Processor Latches Processor Retention Mechanism Retention Mechanism To Install a Processor to ZIF Socket (Applicable to the Motherboard with ZIF Socket Only) To install the processor, follow these steps: 1. If the system microprocessor is already on the motherboard socket, you need to remove it from the motherboard socket. The socket is a Zero Insertion Force (ZIF) socket which has a metal arm at one side. Carefully grasp this arm, move it horizontally away from the socket and lift it up. Eventually you will be able to lift the chip straight up out of the socket. Be careful not to bend any of the pins when removing the microprocessor chip from its socket. The microprocessor chip can be permanently damaged. 2. Carefully align the processor with the correct orientation to the socket on the motherboard. Carefully insert the processor into the socket, and move the metal arm downward to replace it in its original position. Connect the Processor Fan Connector There is a fan attached the processor to prevent the overheating. Connect the processor fan cable to the fan connector that located on the motherboard near the processor and ensure the fan can operate. Otherwise the CPU can overheat and cause damage to both CPU and motherboard. Setting the Processor Speed After you install the processor into the motherboard, set the processor speed by CMOS setup. Technical Reference Booklet 11 BIOS SETUP This chapter discusses Award's Setup Program built into the ROM BIOS. The Setup Program allows users to modify the basic system configuration. [. . . ] The new password will clear the previously entered password from the CMOS memory. You will be asked to confirm the password. Type the password again and press <Enter>. You may also press <Esc> to abort the selection and operate without a password. [. . . ]
