6. Keyboard Wake Up (3 pin KBPWR1)
This allows you to disable or enable the keyboard power up function. Set this
jumper to Enable if you wish to use your keyboard (by pressing <Spacebar>)
to power up your computer. This feature requires an ATX power supply that
can supply at least 300mA on the +5VSB lead. The default is set to Enable.
(The computer will not power ON if you set this to Enable but do not have the
correct ATX power supply. NOTE: This jumper must be set in conjunction
with Wake On PS2 KB/PS2 Mouse/CIR in 4.5.1 Power Up Control.
7. CPU Voltage Setting (3 pin VEN1)
This jumper increases the voltage available to the CPU by 0.2 volts. The
default setting [2-3] only permits normal CPU voltages. Resetting the jumper
to [1-2], enables the extra voltage.
CAUTION! It is advisable not to increase the CPU voltage excessively
to prevent premature failure and/or poor CPU performance.
