Award BIOS Setup Utility
OnChip USB
This field is used to enable or disable the onboard USB controller
supported by the chipset. If you are using a USB peripheral device,
make sure to set this field to Enabled.
USB Keyboard Support
By default, USB Keyboard Support is Disabled. However, if you are
using a USB keyboard under DOS, make sure to enable this function.
Spread Spectrum
Leave this field in its default setting. Do not alter this setting unless
advised by an engineer or technician.
Clock By Slight Adjust
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 stepping.
Important:
Selecting an external bus clock other than 66MHz, 100MHz or
133MHz may result to the processor’s or system’s instability
and are not guaranteed to provide better system performance.
If you selected an option and is unable to boot up the system, there
are 2 methods of going back to its default setting.
Method 1: Clear the CMOS data by setting jumper JP7 pins 2 and
3 to On. All fields in the BIOS Setup will automatically
be set to their default settings.
Method 2: Press the <Insert> key and power button simulta-
neously, then release the power button first. Keep-on
pressing the <Insert> key until the power-on screen ap-
pears. 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 "Chipset Fea-
tures Setup" and set the "Clock By Slight Adjust" field to
its default setting or an appropriate clock frequency.
