²

Load BIOS Defaults

BIOS defaults are the reference settings that allow your system to work at

a  comparatively  low  performance.  When  you  choose  the  option,  the  following
message is displayed:

Load BIOS Defaults (Y/N)? N

If you want to use BIOS default values, press 

Y

, than <Enter>.

³

Load Setup Defaults

Setup  defaults  are  the  settings  that  allow  your  system  to  operate  at  its

highest  performance.  When  you  choose  this  option,  the  following  message  is
displayed:

Load Setup Defaults (Y/N)? N

If you want to use BIOS Setup default values, press 

Y

, than <Enter> to

complete the loading of the settings for best performance.

You  should  first  load  the  best  settings,  than  enter  the  CPU  Soft  Menu  to

set  up  CPU  parameters,  otherwise  the  BIOS  will  replace  set  parameters  by
default parameters.
