Hardware Configuration Settings
Note:
To determine the correct jumper settings, calculate the
CPU Core/Bus Ratio as follows:
Core/Bus Ratio = processor speed divided by base speed
Base Speeds: Celeron = 66MHz, Pentium III = 100MHz
Example: The Core/Bus Ratio of a 466MHz Celeron processor is
calculated as 466MHz divided by 66MHz = 7.0
