BIOS Setup
3.1.7.4 Auto Detect PCI Clk
When enabled, the system will automatically send clock signals to
existing PCI devices.
3.1.7.5 Spread Spectrum
Leave this field in its default setting. Do not alter this setting unless
advised by an engineer or technician.
3.1.7.6 CPU Clock
This field provides several options for selecting the external system
bus clock of the processor. The available options allow you to adjust
the processor’s bus clock by 1MHz increment.
Important:
Selecting an external bus clock other than the default setting
may result to the processor’s or system’s instability and are not
guaranteed to provide better system performance.
If you selected an option other than the default setting and is unable
to boot up the system, there are 2 methods of booting up the
system and going back to its default setting.
Method 1:
Clear the CMOS data by setting JP2 to 2-3 On. All fields in the
BIOS Setup will automatically be set to their default settings.
Method 2:
Press the <Inser t> key and power button simultaneously, then
release the power button first. Keep-on pressing the <Insert> key
until the power-on screen appears. This will allow the system to boot
according to the FSB of the processor. Now press the <Del> key
to enter the main menu of the BIOS. Select “Frequency/Voltage
Control” and set the “CPU Clock Ratio” or “CPU Clock” field to its
default setting or an appropriate frequency ratio or bus clock.
Note:
Use a PS/2 or AT (requires a DIN to mini DIN adapter) key-
board for method 2.
