What is the importance of MAX II CPLD in the Cyclone III FPGA development board?

Is the CPLD device used to store the FPGA configuration for the booting the bitstream dumped into the EPCS flash device? (Switching/control logic stored in the CPLD??) The rotary switches provided...

I'm not sure which Cyclone III dev kit you are referring to but the Cyclone III dev kit is not built with EPCS device. Typically there is a CFI flash device populate on the dev kit. The MAX II device on the dev kit work as the system controller on the board to perform the FPGA configuration, programming flash, clock and power monitoring and others. You can refer those information from the reference manual in the dev kit installation folder.
