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
supports75MHz host bus frequency for Cyrix CPUs. Beware that
75MHz host bus frequency is over the specification of this chipset.
Therefore, you hav to use high quality devices to meet the standard of
these CPUs, i.e., high quality DRAM and VGA cards.
