Award BIOS Setup Utility
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.
CPU/PCI Clock (MHz)
This field provides several options for selecting the external system
bus clock of the processor. When selecting the external bus clock, the
PCI clock will at the same time appear next to the external bus
clock selected. For example, if you selected “66.8/33.4”, 66.8MHz is
the external bus clock and 33.4MHz is the PCI clock. Regardless of
the type of processor used, the default setting is “Default”. Under
this setting, the system will run according to the processor’s clock
frequency.
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 other than “Default” 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 JP6 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 "CPU/PCI Clock (MHz)" field
to "Default" or an appropriate clock frequency.
Note:
Use a PS/2 or AT (requires a DIN to mini DIN adapter)
keyboard for method 2.
