CPU Operating Speed:
This option sets the CPU speed.
In this field, the CPU speed is indicated like this:
CPU speed = External clock * Multiplier factor
Select the CPU speed according the type and the speed of your CPU.
【Note 1】For Intel Pentium II MMX CPUs, you can
following settings:
【Note 4】User define external clock and multiplier
➤ User Define
➤ 83MHz
Normally, we do not recommend that you use the "User Define" option to
setup CPU speed and multiplier factor. This option is for setup of future CPUs
whose specifications are still unknown. The specifications of all present CPUs
are included in the default settings. Unless you are very familiar with all CPU
parameters, it is very easy to make mistakes when you define by yourself the
external clock and the multiplier factor.
