Cpu Type Configuration; Step 1: Frequency Setting; Pentium Ð 90/100 Cpu Settings (1.5 X Clock) - SOYO 82430 TX User's Manual & Technical Reference

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

Note: 1. You must equip the CPU with a fan and heat sink for system
stability.
