2. Keyboard Power (KBPWR)

This allows you to disable or enable the keyboard wakeup function. Set to Enable if

you want to use your keyboard (by typing <SPACE>) to wake up your computer.

This feature requires an ATX power supply that can supply at least 300mA on the

+5VSB lead and new BIOS support. The default is set to Disable because not all

computers have the appropriate ATX power supply. Your computer will not function

if you set this to Enable and if you do not have the right ATX power supply.
