Attach the Retention Mechanism to the Mainboard. Push the Plastic
lock to secure the Retention Mechanism into the mainboard.

Secure the processor by

pulling up the Retention
Insert the processor
Mechanism Processor
like inserting a PCI or
Lock

To release the
processor, push the
Retention Mechanism
Processor lock down

Step 2: Install the Processor.

Insert the Processor like inserting a PCI or an ISA card.

Step 3: Lock the Processor.

Lock the processor by pulling up the Retention Mechanism
processor lock shown above.

2.1-2 CPU Core Speed Derivation Procedure

1. This mainboard can auto-detect the Core/Bus (Fraction) ratio of the CPU

If CPU Clock = 66MHz

Core/Bus ratio = 3.5
then CPU core speed = Host Clock x Core/Bus ratio
= 66MHz x 3.5
= 233MHz

Note: CPU Vcore and Vi/o can be modified through CMOS.

Vcore for CPU.
Vi/o for Northbridge.

2.1-3 Overclocking Jumper: SW2/SW3

Overclocking is a process of operating a CPU/Processor beyond its
specified frequency. SW2/SW3 is used for overclocking.

SW3 SW2

SW2 SW3 Feature

Automatically detect 66MHz,100MHz

CPU Bus Frequency

Virtually set CPU Bus Frequency

into 100MHz

Note If you used this jumper for overclocking, you also need to modify the
CPU Bus ratio thorugh CMOS.

2.1-4 Fan Power Connectors: CPUFAN/PSFAN/SYSFAN

These connectors support system cooling fan with +12V. It supports three
pin head connector. When connecting the wire to the connector, always
take note that the red wire is the positive and should be connected to the
+12V, the black wire is Ground and should be connected to GND. If your
mainboard has System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of this function.

For fans with fan speed sensor, every rotation of the fan will send out 2
pulses. System Hardware Monitor will count and report the fan rotation
speed.
Note: 1. Always consult vendor for proper CPU cooling fan.
2. CPU FAN supports the FAN control, you can install PC Alert
utility, this will automatically set the CPU FAN Speed by CPU
temperature.

There are 5 PCI slots and 2 ISA slots. All PCI slots can be used as master.
But since the 1st and 5th PCI slots share the same bus master signal, only
one of these slots can be used as a master at a time; which means that if a
