Installing the Motherboard
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 momen-
tary-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
momentary-contact switch that is normally open. The switch should main-
tain contact for at least 50 ms to signal the power supply to switch on or off.
The time requirement is due to internal de-bounce circuitry. After receiving
a power on/off signal, at least two seconds elapses before the power supply
recognizes another on/off signal.
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 making changes to jumpers on the motherboard, or 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.
