Switches
The following figure shows the location and default settings of the DIP
switches on the motherboard.
DO NOT change the settings of the Reserved switches.
1.
CPU external frequency selection (SW1 Switches 1-5)
This option tells the clock generator what frequency to send the CPU.
This allows the selection of the CPU’s external frequency (or Bus
Clock). The BUS Clock multiplied by the Frequency Multiple equals the
CPU’s internal frequency (the advertised CPU speed).
To select the CPU external frequency using the DIP switches, ensure
that the JEN jumper is set to jumper mode.
