2. Keyboard Power Up (KBWK)
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. The default is set to Disable because not all
computers have the appropriate ATX power supply. Your computer will not func-
tion if you set this to Enable and if you do not have the right ATX power supply.

3. AGP Frequency Selector (AGPFS)
This option sets the frequency ratio between the AGP bus frequency and the
CPU bus frequency. The default sets the AGP bus frequency to be 2/3 of the
CPU bus frequency.
