Jumpers

1. 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).

2. SMB2.0 (two 2-pin SMB20)
These jumpers allow you to enable or disable the SMBus 2.0 feature
supported on the motherboard. By default, these jumpers are shorted
(jumper caps on) to disable the feature. If you wish to install PCI
devices that comply with SMBus 2.0 specification, remove the jumper
caps to enable the SMBus 2.0 feature.
