Using BIOS setup
42
Using BIOS setup
BIOS (Basic Input/Output System) is a layer of software, called
firmware, that translates instructions from other layers of
software into instructions that the Joybook hardware can
understand. The BIOS settings are needed by the Joybook to
identify the types of installed devices and establish special
features.
When and how to use BIOS
setup
You need to use BIOS setup when:
• You see an error message on the screen requesting you to run
BIOS setup.
• You want to restore the factory default settings.
• You want to modify some specific settings according to the
hardware.
• You want to modify some specific settings to optimize system
performance.
To run BIOS setup, press the <F2> key immediately when the
BenQ logo appears on the screen during system startup. The
logo shows up on the screen for only a few seconds, so you must
press the <F2> key at the time.
The BIOS setup screen can be divided into three areas:
• On the top line is the menu bar containing the titles of
available menus. Each menu title contains a specific menu.
• The center left column of the menu contains information
regarding the current settings of the system. If you open a pull-
down menu and select an item that provides multiple options,
the left column will display a submenu where you can make
further selections.
• The right column of the menu provides:
• Help information about the current menu selected.
When a menu item is highlighted, more detailed
information is given.
BIOS settings are specific to your Joybook hardware. Do NOT
change existing BIOS settings unless you are sure they need
to be changed, and are aware of the consequences. Any
incorrect BIOS settings may degrade the performance,
operation and functionality of your Joybook.
