2. Keyboard Power Up (KBPWR)
This allows you to disable or enable the keyboard power up function. Set to
Enable if you want to use your keyboard (by pressing <Spacebar>) to power up
your computer. This feature requires an ATX power supply that can supply at
least 300mA on the +5VSB lead and the new ACPI BIOS support. The default is
set to Disable because not all computers have the appropriate ATX power sup-
ply. Your computer will not function if you set this to Enable and if you do not
have the right ATX power supply.
