5.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).

6.VCORE over-voltage (3-pin OVER_VOLT1)

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).
