The Main BIOS setup screen has two main frames. The left frame displays all the options
that can be configured. Grayed-out options cannot be configured; options in blue can. The
right frame displays the key legend. Above the key legend is an area reserved for a text
message. When an option is selected in the left frame, it is highlighted in white. Often a
text message will accompany it.
System Date
Use this function to change the system date.
Select System Date using the Up and Down <Arrow> keys. Enter the new values through the
keyboard. Press the Left and Right <Arrow> keys to move between fields.
The date setting must be entered in MM/DD/YY format.
System Time

Select System Time using the Up and Down <Arrow> keys. Enter the new values through the
keyboard. Press the Left and Right <Arrow> keys to move between fields.
The time setting is entered in HH:MM:SS format.
Note: The time is in 24-hour format. For example, 5:30 A.M. appears as 05:30:00, and 5:30
P.M. as 17:30:00.
Access Level
Display the access level of the current user in the BIOS.
