two points labeled CLRTC, (3) Turn on your computer, (4) Hold down
during bootup and enter BIOS setup to re-enter user preferences.

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 ) 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.
