Using Computer Setup to Reset CMOS

of the screen, press the
F10 key. Press Enter to bypass the title
screen, if necessary.

If you do not press the F10 key while the message is displayed, you
must turn the computer off, then on again, to access the utility.

and Exit. This resets the soft settings that include boot sequence
order and other factory settings. It will not, however, force hardware
rediscovery.
