2. CPU frequency selection (SW1 Switches 1-5)
This option tells the clock generator what frequency to send the CPU,
and to the AGP and PCI slots. This allows the selection of the CPU
external frequency (or Bus Clock).
To select the CPU external frequency using the DIP switches, ensure
that the J6 jumper is set to jumper mode.

External Frequency Selection
Set the CPU frequency only to the recommended settings.
Frequencies other than the recommended CPU bus frequencies are
not guaranteed to be stable.
3. Keyboard power (3-pin KBPWR)
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.
