2. CPU 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 JEN jumper is set to jumper mode.

Frequencies other than the recommended CPU bus frequencies are not guaranteed to be stable. 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).
