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