[. . . ] 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. [. . . ] 1. 0, 1X/2X model support). CAUTION Static electricity can harm delicate components of the motherboard. To prevent damage caused by static electricity, discharge the static electricity from your body before you touch any of the computers electronic components. Technical Reference Booklet 5 Motherboard Layout (Model Code No. - 35C93100XX) The following diagrams show the relative positions of the jumpers, connectors, major components and memory banks on the motherboard. 1 JP1 1 JP5 1 JP 7 1 JP20 CN32 1 1 JP 23 JP 8 1 1 1 JP 5 1 JP 5 2 JP 5 3 JP 5 4 1 1 NOTE 1) 2) Be sure to check the cable orientation in order to match the colored strip to the pin 1 end of the connector. When you start up the system, please wait for 5 seconds after you power on AC. Hardware Configuration 1 1 1 1 1 6 Jumper Settings This chapter explains how to configure the motherboard's hardware. 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 1 1 JP51 JP53 JP52 JP54 2 1 2 1 2 1 2 1 JP29 JP20 JP1 JP5 1 2 1 1 1 1 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, JP5, 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 you use 100MHz Host Bus Speed CPU, DIMM RAM must be PC100 standard. Most PGA370 CPU is frequency multiplier locked, no CPU speed chang will be seen even if the frequency multiplier in CMOS setup is changed .

The feature is enabled in Integrated Peripherals Menu of CMOS setup. (1) Single Key Turn On - if you set a single key password, the system will turn on immediately after you press the password key (440BX/ZX only). (2) Keys Sequence Turn On - if you set a password with more than one character, ie. a combination of keys, the system will turn on after you press the password key sequence and then a <enter>. Please notice that the power button will have no function if the keyboard password power on feature is enabled. Hardware Setup To Install DIMMs 1. Holding the DIMM by the edges, remove it from its antistatic package. Make sure the clips at either end of the socket are pushed away from the socket. 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. Hardware Setup 10 BIOS Setup This chapter discusses Award's Setup Program built into the ROM BIOS. [. . . ] 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. [. . . ]
