2. CPU Frequency Selection (DSW1 Switches 1-5)
This option tells the clock generator what frequency to send the CPU.
This permits 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).

3. Keyboard Power (3-pin KBPWR1)
This jumper allows you to enable or disable the keyboard wake-up
feature. Set this jumper to pins 2-3 (+5VSB) if you wish to wake up
the computer when you press a key on the keyboard (the default is
the Space Bar). This feature requires an ATX power supply that can
supply at least 1A on the +5VSB lead, and a corresponding setting in
the BIOS (see section 4.5.1 Power Up Control).

Set the CPU frequency only to the recommended settings.
Frequencies other than the recommended CPU bus frequencies are
not guaranteed to be stable.
To select the CPU external frequency using the DIP switches, ensure
that the JEN jumper is set to jumper mode.
