3.1 CPU Configuration
CPU Socket-A Configuration Steps:
1. Please find the CPU socket on your motherboard and pull the lever sideways away
from the socket, then raise the lever up to a 90-degree angle.
2. Find Pin-1 in the socket and look for the white dot or cut edge in the CPU. Match
Pin-1 with the white dot/cut edge then insert the CPU.
3. Press the lever down. Then Put the CPU fan on the CPU socket and clasp it with
the socket. When the CPU fan is fixed to the CPU socket, put the fan’s power port
into the CPUFAN. After finishing all these steps, the CPU is ready for use.

CPU Headers Installation
These three headers introduced here are most related to your
CPU installation. They are the power headers to all the cooling
fans on your motherboard. These fans play an important role on
decreasing the temperature of your system.
* The layout is KM266 PRO
We strongly recommend you to install
CPU fanon CPU FAN connector.

HD LED (Hard Drive LED Connector)
This connector can be attached to an LED on the front panel of
a computer case. The LED will flicker during disk activity. This
disk activity only applies to those IDE drives directly attached to
the system board.
RST (Reset Button)
This connector can be attached to a momentary SPST switch.
This switch is usually open and when closed will cause the
motherboard to reset and run the POST (Power On Self Test).
ACPI PWR-LED (ACPI Power LED Connector)
This connector can be attached to an LED on the front panel of
a computer case. The LED will illuminate while the computer is
powered on and it will flashing during power saving mode。
PWR ON (Power Button)
This connector can be attached to a front panel power switch.
The switch must pull the Power Button pin to ground for at least
50 ms to signal the power supply to switch on or off. (The time
required is due to internal debounce circuitry on the system
board). At least two seconds must pass before the power supply
will recognize another on/off signal.

An offboard speaker can be installed on the motherboard as a
manufacturing option. An offboard speaker can be connected to
the motherboard at the front panel connector. The speaker
(onboard or offboard) provides error beep code information
during the Power On Self-Test when the computer cannot use
the video interface. The speaker is not connected to the audio
subsystem and does not receive output from the audio
subsystem.

4.11 Floppy Disk Connector: FDC
The motherboard provides a standard floppy disk connector
(FDC) that supports 360K, 1.2M, 1.44M and 2.88M floppy disk
types. This connector supports the provided floppy drive ribbon
cables.
4.12 Hard Disk Connectors: IDE1/IDE2
This motherboard has a 32-bit Enhanced PCI IDE Controller that
provides PIO Mode 0~4, Bus Master, and Ultra DMA / 33, Ultra
