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.
5. V
CORE
over-voltage (3-pin OVER_VOLT)
When enabled, this jumper allows CPU V
CORE
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 V
CORE
setting range of
+1.5V to +1.7V, and Willamette has 1.75V to 1.85V. You may adjust the
CPU V
CORE
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).
