The 386/32 uses an 80386 microprocessor that runs at a clock speed either 16MHz or 20MHz. In the configuration using 100 nanosecond DRAM the processor runs at near zero wait states. The 386/32 is wait­state selectable for either near zero (.7) or one-wait state and can be software switched between low and high speed modes. By using the extended setup program that is provided with the 386/32 AMI you can select the microprocessor clock speed.
