Installing the Mainboard
P-Rating
The P-Rating was defined by some manufacturers other than Intel to rate
the performance of their CPU in comparison with Intel Pentium CPUs. For
instance, Cyrix 6x86 P166+ has a higher actual speed compared with Intel
Pentium P166, its internal clock needs only 133MHz versus 166MHz for
Intel' s product. The main reason is that Cyrix has improved the internal
architecture of the 6x86 CPU, which means that with the same internal
clock speed, the actual clock speed will be different.
Having read the related terminology above, please refer to the information in
appendices B, C or D for the type and specifications of your own CPU. We
suggest that you note down these specifications, which will help you when you
install the CPU.
CPU Settings:
To configure the speed and the voltage of the CPU, you must enter to the CPU
