To start the BIOS Setup utility:

1.  Turn on or restart your computer.

2.  Wait until the Mitsubishi Electric logo appears on the screen.

3. Press 

the 

F

2 key.

4.  If you have previously defined a Supervisor password, you are

prompted for it before BIOS Setup starts.

BIOS Setup might start on its own for three reasons:

♦ 

The power-on self-test (POST) detects a configuration error or
fault. This may be signalled by one or more POST error
messages. If a persistent fault is indicated, make a note of any
error messages and the current configuration settings before
calling an authorised maintainer.

♦ 

The CMOS battery may be running down. This may cause
spurious POST error messages. If this happens every time you
turn on the computer, you may have to change the battery.

♦ 

The computer’s configuration may have changed, for example
by the addition of more system memory or an expansion card.
In this case you may have to define the new configuration.

Use the keys listed in the legend bar at the bottom of the BIOS
Setup screen to make your selections or exit the current menu.

Sub-menus are marked by a   pointer. To display a sub-menu, use
the arrow keys to move the cursor to the sub-menu you want, then
press 

ENTER
