CPU Speed, CPU Clock Multiplier, CPU/PCI Clock Select
The motherboard allows users to set the CPU speed through
the BIOS. The parameters in setting the CPU speed include
CPU Clock
Multiplier
and
CPU Clock/PCI Clock
.
In the initial setup, the system automatically detects the bus speed (front
side bus) of the CPU (66MHz or 100MHz). Press the
↑
and
↓
keys to
change the CPU speed or press the PageUp or PageDown key to see the
selections for CPU Clock Multiplier and CPU/PCI Clock Select.

CPU Warning Temperature
This field sets the threshold value for the CPU warning temperature. An
alert is sounded through the system’s speaker when the CPU temperature
exceeds the set value. The function prevents overheating and damage on
the CPU.
