S2 (System Frequency select) Switches S2-1 through S2-3 set the ratio of CPU Frequency/Bus Frequency.

This is set to 4X for the K6-2/400 MHz processor.

Ratio	S2-1	S2-2	S2-3
K6-2/400 (4X)	Off	On	On

S2 (System Frequency select) Switches S2-4 through S2-10 are set to correspond to the CPU/SDRAM/PCI/AGP frequency.
