2. Processor system bus selection (3-pin PSBSEL1)
In jumper mode, the PSBSEL1 jumper allows selection of either the CPU
or the DSW1 to determine the CPU frequency. When set to pins 1-2, the
CPU frequency depends on the CPU system bus (533MHz or 400MHz).
When set to pins 2-3, the CPU frequency depends on whatever is the
setting of DSW1. Refer to the next item for the DSW1 settings.
When the PSBSEL1 jumper is set to pins 1-2 (CPU), set the DSW1
switches as shown below.
The PSBSEL1 jumper does not work under JumperFree mode.

3. CPU external frequency selection (DSW1 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 JEN1 jumper is set to jumper mode.
