Award BIOS Setup Utility
Open Slight Adjust
The default setting is Disabled - the system will run according to
the FSB of the CPU. If you want to set the external bus clock
manually, select Enabled and enter the desired bus clock in the
Clock By Slight Adjust field.
Important:
If you manually selected the CPUs FSB (using JP9 and JP10)
instead of using its default setting which is Auto, make sure this
field is set to Disabled.
Clock By Slight Adjust
If the Open Slight Adjust field is set to Enabled, you can enter
the desired external bus clock in this field. The feature allows you to
set the external bus clock by 1MHz stepping - ranging between
66MHz and 166MHz.
CPU Clock Ratio
This field is used to select the frequency ratio of the processor.
Important:
The frequency ratio of some processors may have been
locked by the manufacturer. If you are using this kind of
processor, setting an extended ratio for the processor will
have no effect. The system will instead use its factory
default ratio.
The frequency ratio of processors greater than 8x has been
locked by the manufacturer and will no longer have the
flexibility of using extended ratios. Therefore, the system will
use the processors factory default ratio.
If, in the Clock By Slight Adjust or CPU Clock Ratio field, 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 JP5 to 2-3 On. All fields in the
BIOS Setup will automatically be set to their default settings.
