Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indication that data
is being read from or written to the hard drive. For the LED to function properly, an IDE
drive should be connected to the onboard IDE interface. The LED will also show activity
for devices connected to the SCSI (hard drive activity LED) connector.
Power/Sleep/Message waiting LED
Connecting pins 2 and 4 to a single or dual-color, front panel mounted LED provides power
on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pin 5 and 7 to a momentary-contact
switch that is normally open. When the switch is closed, the board resets and runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a momentarycontact switch that is normally open. The switch should maintain contact for at least 50 ms
to signal the power supply to switch on or off. The time requirement is due to internal debounce circuitry. After receiving a power on/off signal, at least two seconds elapses before
the power supply recognizes another on/off signal.
Installing the Motherboard
Installing Hardware
Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the motherboard or any of the surface-mount
resistors with the clip of the cooling fan. If the clip of the cooling fan
scrapes across the motherboard, you may cause serious damage to the
motherboard or its components.
On most motherboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the clips.
Also, install the cooling fan in a well-lit work area so that you can clearly
see the motherboard and processor socket.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and system bus
frequency for the processor. You may be able to change these settings by changing the
settings in the system Setup Utility. We strongly recommend that you do not over-clock
processors or other components to run faster than their rated speed.
Warning: Over-clocking components can adversely affect the reliability of
the system and introduce errors into your system. Over-clocking can
permanently damage the motherboard by generating excess heat in
components that are run beyond the rated limits.
13
This motherboard has a Socket 939 processor socket. When choosing a processor, consider
the performance requirements of the system. Performance is based on the processor design,
the clock speed and system bus frequency of the processor, and the quantity of internal
cache memory and external cache memory.
Installing the Motherboard
