4. 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 (see section 4.5.1 Power Up Control).

5. DDR voltage (4-pin DDR_OV)
This jumper allows you to select the voltage supplied to the system
memory by changing the jumper setting.
DISABLE = 2.5V
STAGE1 = 2.6V
STAGE2 = 2.7V
It is recommended that you keep the default setting (Disable) for
system stability. Setting to Stage1 and Stage2 does not guarantee
better system performance.
