CPU Type Configuration

This section shows you how to configure your CPU step by step. Note that you need to check the CPU voltage before installation. This board supports the Intel P54C/P55C/MMX, Cyrix 6x86/6x86L/6x86MX, and AMD 5K86/K5/K6 CPUs. With the MMX technology supported, you should be able to use MMX CPUs and configure these CPUs as normal dual voltage CPUs.

Step 1: Frequency Setting
