3.HARDWARE SETUP

3)CPU Core:BUS Frequency Multiple (DSW-Switches 1-4)

This option sets the frequency multiple between the Internal frequency of the CPU and the CPU’s External frequency. These must be set in conjunction with the CPU Bus Frequency.

NOTE: In JumperFree™ mode, all dip switches (DSW) must be set to OFF.
