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. VCORE over-voltage (3-pin OVER_VOLT)

When enabled, this jumper allows CPU Vcore ranges of 1.5V to 1.8V
for Pentium 4 Northwood CPU and 1.75V to 1.95V for Pentium 4
Willamette CPU.

When this jumper is disabled, Northwood has a Vcore setting range of
+1.5V to +1.7V, and Willamette has 1.75V to 1.85V. You may adjust the
CPU VCore through the BIOS Setup.

Setting to a very high core voltage may cause permanent damage to
the CPU. It is recommended that you keep the default setting
(Disable).
