Award BIOS Setup Utility
CPU/PCI Clock (MHz)
The options are Default, 66.8/33.4, 75/37.5, 83.3/41.65, 100.3/33.4,
103/34.33, 105/35, 110/36.67, 112/37.33, 115/38.33, 120/40, 124/
31, 124/41.33, 133/33.25, 133/44.33, 140/35 and 150/37.5. When
selecting the external bus clock of your processor, 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 pro-
cessor used, the default setting is "Default". Under this setting, the
system will run according to the processor's clock frequency. 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 following the procedure in
section 2.5 (chapter 2) of this manual. All fields in the
BIOS Setup will automatically be set to its default
settings.
Method 2: Press the <Insert> key and power button simulta-
neously, then release the power button first. You must
keep-on pressing the <Insert> key until the power-on
screen appears. This will allow the system to boot ac-
cording to the FSB of the processor. Now press the
<Del> key to enter the Award BIOS setup utility. Select
"Chipset Features Setup" and set the "CPU/PCI Clock
(MHz)" field to "Default" or an appropriate clock fre-
quency.
Note:
When using a 66MHz FSB processor, the AGP clock and
the CPU's external bus clock are similar. When using a
100MHz FSB processor, the AGP clock is 2/3 of the
CPU's external bus clock.
Spread Spectrum
Leave this field in its default setting - Disabled. Do not alter this setting
unless advised by an engineer or technician.
