2-1 Installing a CPU Processor for Socket A

The Socket A, designed for AMD® Athlon XP/Athlon/Duron processors, has been
incorporated as a standard motherboard specification. To insert your CPU into Socket A
please do the following:

1. Locate a cut edge on the top surface of the CPU close to one if it’s corners. The same
corner will also be cut off, leaving a noticeable notch in the CPU’s corner. These
markings indicate Pin 1 of the CPU.

2. Pull up the lever of Socket 462 so that it is perpendicular with the surface of the
motherboard. Gently insert the CPU with Pin 1 at the same corner of Socket 462 that
contains the end of the lever. Allow the weight of the CPU to push itself into place. Do
not apply extra pressure as doing so may result in damaging your CPU. Snap the lever
back into place.

installing a motherboard. Before connecting t
make sure it is not connected to the power source.

PW1 (ATX Power Supply Connector)

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 its minimum power state.
The ATX 12V power supply has a new +12V (4-pin) and +5V/3.3V (6-pin) auxiliary
power connector. To enable the delivery of more +12 VDC and +5/3.3V VDC current to
the motherboard.

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. 5)

Blinking LED in Suspend Mode

While in Suspend mode, the LED light on the front panel of your computer will flash.
Suspend mode is entered by pressing the Override Power Button

, pushing the Green
button on your ATX case, or enabling the Power Management and Suspend Mode options
in BIOS's Power Management menu. (See section 3.5)

Poly-fuse Over Current Protection

The poly-fuse protects the system from dangerous voltages that the system might be
exposed to via the keyboard or USB connector. In case of such exposure, the poly-fuse
will immediately be disconnected from the circuit, just like a normal fuse. After being
disconnected for a certain period of time, the poly-fuse will return to its normal state.
Then the keyboard or USB connector can function properly again. Unlike conventional
fuses, the poly-fuse does not have to be replaced, relieving the user wasted time and
inconvenience.

CN1A (Front Panel Connector)

1. PWR-SW (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.

power button rapidly will switch the system to Suspend mode. Any occurrence of
external activities such as pressing a key on the keyboard or moving the mouse will
bring the system back to Full-On. Pushing the button while in Full-On mode for more

two connectors.)

3. G-BTN/G-LED (Green Button Switch/LED Connector)
Some ATX cases provide a Green button switch, which is used to put the system in
Suspend mode. In Suspend mode, the power supply to the system is reduced to a trickle,
the CPU clock is stopped, and the CPU core is in its minimum power state. The system
is woken up whenever the keyboard or mouse is touched. The system resumes in
different ways as defined by Power Management Setup screen in BIOS.

4. RESET (System Reset Switch Connector)
This connector should be connected to the reset switch on the front panel of the system
case. The reset switch allows you to restart the system without turning the power off.
