Control of System Speed
System speed can be controlled by keyboard and turbo switch. To change the speed by
keyboard, use the minus sign (-) and the plus sign (+). Press <control> + <alt> + <“-”> for
slow speed and <control> + <alt> + <“+”> for fast speed.

Fan voltage
There are two different voltages available for CPU fans; +5 volts and + 12 volts.Select a
proper setting for jumper JP1 before you turn on the computer.
3.10
Fan Connector
This connector allows the CPU fan to draw current directly from the motherboard, without
having to rely on a separate power connector.
A CPU fan is highly recommended for today’s high speed CPUs. Extreme
high CPU temperature are generated during system operations , and may
cause abnormal hardware behaviour if system is not cool down.
3.11
Reset CMOS
If the setting of the system setup is done improperly it may make the system malfunction.
If this happens, turn off the power and set jumper JP19 to 1-2 to reset the internal CMOS
status register. Next, set the jumper JP19 back to 2-3 and turn on the power. The BIOS
will find the CMOS status register is reset and will regard the setup information invalid, so
it will prompt you to correct the information.
