Using Bios Setup; When And How To Use Bios Setup - BenQ Joybook Lite U121 User Manual

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 Lite hardware can
understand. The BIOS settings are needed by the Joybook Lite to
identify the types of installed devices and establish special
features.
BIOS settings are specific to your Joybook Lite 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 Lite.
