displayed on the diagnostics screen.
Keyboard Commands
The bottom right portion of the Setup screen provides a list of commands that are used to
navigate through the Setup utility. These commands are displayed at all times.
Each Setup menu page contains a number of features. Except those used for informative
purposes, each feature is associated with a value field. This field contains user-selectable
parameters. Depending on the security option chosen and in effect by the password, a
menu feature's value may or may not be changeable. If a value is non-changeable, the fea-
ture's value field is inaccessible and displays as "grayed out."

< Enter >
Select and Execute
Command
The < Enter > key is used to activate sub-menus when the selected
feature is a sub-menu, or to display a pick list if a selected option has
a value field, or to select a sub-field for multi-valued features like time
and date. If a pick list is displayed, the
< Enter > key will select the cur-
rently highlighted item, undo the pick list, and return the focus to the
parent menu.
< Esc > Exit
The < Esc > key provides a mechanism for backing out of any field.
When the < Esc > key is pressed while editing any field or selecting
features of a menu, the parent menu is re-entered.
When the < Esc > key is pressed in any sub-menu, the parent menu is
re-entered. When the < Esc > key is pressed in any major menu, the
exit confirmation window is displayed and the user is asked whether
changes can be discarded. If
No is selected and the < Enter > key is
pressed, or if the < Esc > key is pressed, the user is returned to where
he/she was before < Esc > was pressed, without affecting any existing
any settings. If Yes is selected and the < Enter > key is pressed, setup is
exited and the BIOS returns to the main System Options Menu
screen.
