74 Appendix A: BIOS reference
Introduction
BIOS stands for Basic Input/Output System. It acts as an interface between the
operating system and the hardware. When the computer is turned on, it is the
BIOS that is responsible for booting up the machine, and loading the operating
system that is used to run applications. The computer BIOS image is written on
a 1 Mbyte flash memory chip, installed on Matrox 4Sight-M.
You can change computer BIOS settings by running a utility program called Setup,
which can be accessed soon after turning on your unit

This appendix shows you how to access and change the settings of the BIOS Setup
utility. It also explains the different messages and flash codes displayed by BIOS
during the course of your unit’s operation.

settings if you make additions to your unit.
